Termination Systems for Polymeric Insulated Cables up to 72 kV

Application

Raychem’s terminations up to 72 kV are suitable for all climates and environments, even severely polluted areas, and for all installation condi-tions, including top feed installation. The factory-engineered kits contain a proven termination system which saves space, facilitates installation and enhances system reliability. The spe-cial design of the termination, which incorporates pre-coated tracking resistant sealants that melt during the shrinking process, results in a reliable and lasting barrier against moisture and corrosion.

Features

The slim, compound-free Raychem Terminations are suitable for indoor and outdoor use on all polymeric cables for voltages from 42 kV up to 72 kV.

• Easy installation• Non-tracking, heat-shrinkable outer

insulation• Heat-shrinkable stress control

sleeves• Pre-coated track resistant sealant• Water and corrosion resistant• Light-weight components• Isolated base plate for

sectionalisation• High reliability

11

Major Design Elements

Kit content:The kit contains a limited number of light-weight components with unlimited shelf life under normal stor-age conditions. The heat-shrinkable sleeves are extremely versatile, and accommodate a wide range of cable diameters. Four basic kits cover all cable sizes, permitting reduced inven-tories and effi cient stocking policy.The lightweight of the components and limited volume of the kits facili-tate safe and easy transportation and handling. All components are included in a single box. The set of pre-engineered compo-nents requires no special or expensive tools for installation. Installation involves a simple set of standard procedures with no soldering re-quired. Neither does the termination require fi lling with oil or compound. Risk of leakage is avoided, and fi lling and topping-up time on the job site is saved.

High Performance Material:Raychem terminations are made of a specially formulated material with excellent tracking and erosion resist-ance characteristics. Accelerated and natural weathering tests which have been carried out at Raychem facilities and independent test sites around the world have demonstrated that the terminations are UV and water resistant and perform reliably even when exposed to sudden temperature variations. A Tracking and Erosion Test as per ASTM D2303 showed no tracking. IEC 112 was also conducted with no erosion or tracking observed.

Electrical Stress Control:Screened or shielded power cables require electrical stress control in order to reduce the electrical stresses at the end of the screen and at the termination surface to avoid partial discharge and surface corona under all service conditions. Corona or electrical discharge can ultimately destroy the cable insulation, causing premature failure.Raychem’s stress control sleeves have electrical properties that smooth out the electrical fi eld at the end of the cable. This is achieved by the unique resistive and capacitive properties of the heat-shrinkable materials.

A Universal System:The material used in these termina-tions is suitable for all climates and environments. It is not susceptible to damage from transportation or vandalism. The termination has a discreet, low profi le which allows it to blend into landscapes.

Dry Self-Supporting Outdoor Termination OHVT up to 145 kV

Application

The dry self-supporting termination is designed for voltage classes up to 145 kV and operation under severe environmental conditions. It is free from any insulating liquid or gel. Polymeric insulated cables of various designs can be adopted with respect to shielding and metal sheath. The polymeric housing with long creepage length covers extreme pollution levels according to IEC 60071-1 1996, IEC 60071-2 1996 and IEEE-1313.1-1996. Its mechanical performance is similar to conventional oil-fi lled terminations with composite housing.

The termination is easily separable and consists of a plug-in part and an epoxy resin insulator protected with directly moulded silicone shed hous-ing. Due to the short cable cutback dimensions of the plug-in the time required to install the termination is very short and can be further reduced in case of short cable links by pre-in-stalling the plug-in on the shop fl oor.

The plug-in is similar to the plug-in used with Tyco’s dry switchgear/ transformer termination.

Dry Compact Switchgear & Transformer Termination PHVS & PHVTfrom 72 kV up to 145 kV

Application

The dry compact switchgear termina-tion for voltage classes up to 145 kV is designed to be installed in cable entry housings of gas-insulated switchgear (GIS). It complies with IEC 62271-209 standard, which essentially specifi es the interfaces between the termina-tion and the switchgear.Therefore the termination will fi t into all GIS complying with IEC 62271-209.An adapter is available to match the dimensions of wet (oil-fi lled) type terminations, which are also specifi ed in IEC 62271-209.

The termination operates in SF6 but also in insulating liquids like trans-former oil. A corona shield at the top of the termination then provides the necessary shielding of the terminal.The termination is easily separable and consists of a plug-in part and an epoxy resin insulator. The insulatorcan be installed by the GIS or trans-former manufacturer already at the factory saving installation time onsite and reducing the risk of contamina-tion of the cable entry housing. In case of short cable links and due to the short length and light weight of the plug-in part it can be also pre-installed by the cable manufacturer further reducing the time required to install a substation.

The epoxy-resin insulator (4) with embedded multi-contact electrode forms the gas pressure-tight interface between GIS or transformer cable entry and the plug-in part of the termination. It is attached to the cable entry housing with the fi xing ring (7).

The torque-controlled shear-off bolt connector (3) with multi-contacts fi ts the cable conductor. The connector is suitable for stranded aluminium and copper conductors and can be modifi ed to accept solid conductors as well. No special tool is required to install the connector.


A metal spring-loaded compression ring (6) presses the rubber stress cone into the specially shaped interior of the resin housing, ensuring a uni-form contact pressure and electrically sound interface.

A corona shield (1) can be easily attached to the termination for use in insulating liquids. Compared with IEC 60859 wider clearances apply in this application.

The cable outer serving is adapted through a gland system (8), which addresses the individual shielding and armouring. The gland system also secures the cable.

An adapter (2) can be used to match the dimensions of wet type switch-gear and transformer terminations which makes the termination an ideal choice for replacing oil-fi lled termina-tions.

The epoxy-resin insulator (3) with embedded electrode forms the gas pressure-tight interface between GIS or transformer cable entry and the oil-fi lled cable compartment of the termination. It is attached to the cable entry housing with the fi xing ring (6).

To fi t the cable conductor, torque-controlled shear-off bolt connector (2) or crimp-type connectors are available. The connector is suitable for stranded aluminium and copper conductors and can be modifi ed to accept solid conductors as well. No special tool is required to install the mechanical connector. The fl exible double sealing system is installer-friendly and ensures persistent leak tightness of the top assembly. Heat shrinkable polymeric tubing contain-ing oil-resistant sealant encapsulates the connector barrel and the poly-meric insulation transition.


The interface between stress cone, cable insulation and inner GFR housing is fi lled with silicone oil (4) through a fi lling nozzle at the base plate.

The cable outer serving is adapted through a gland system (8), whichaddresses the individual shielding and armouring of the cable. Heat shrink-able tubing is used to seal the cable gland.

No specialists required. A qualifi ed medium-voltage jointer will be trained in one day.

• Pre-engineered wall thickness:All product dimensions are set and checked at the factory before the product is shipped to the fi eld.

• Time savings:Due to short installation time out-ages are kept to a minimum in repair situations.

• High reliability:The combination of long experience and rigorous testing to international standards leads to high joint reli-ability.

Joints for Polymeric Insulated Cables EHVS from 42 kV up to 72 kV

27


Designed for easy jointing:The Raychem joint design comprises of a connector that allows even large cross-sections to be jointed and two dual-wall, heat-shrinkable sleeves. A heavy-walled co-extrusion of two layers of red insulation forms the inner sleeve. The outer sleeve consists of a thick layer of red insulation co-extrud-ed under a black outer conductive layer which acts as the joint screen.

Kit Content:The set of pre-engineered compo-nents and the Raychem connector require no special installation tools. After placing the heat-shrinkable components over the cable end, the connector is installed by tightening the special bolts, which shear off cleanly when the correct contact force is reached. Each sleeve in turn is placed over the connector area and shrunk down. Copper shielding mesh and an adhesive-coated outer sleeve for water sealing then complete the joint.

Controlled-torque Connector:The connector design allows cables to be jointed without special tools, heat treatment as dressing/fi ling after installation. Shear-head bolts ensure a pre-engineered electrical connection. The shear-head bolts break off at a pre-determined level below the outer surface of the connector, at a defi ned torque. This ensures the correct con-tact pressure is reached every time. The stable voltage drop provided by this concept has been demonstrated in fi eld installations which closely follow the predictions of long-term load-cycling tests.Comprehensive qualifi cation proce-dures like IEC 61238-1996 and ANSI 119.4 1993 prove the excellent long-term performance.

28

Electrical Stress Control:A material with stress adjusting characteristics is applied onto the connector and cable screen ends. This heat-shrinkable sleeve incorporates a conductive coating in the connector area which equalizes potential in the manner of a Faraday cage. It extends over the dielectric to accommodate possible insulation shrink-back.

Cross-bonding / shield break:The use of heat-shrinkable sleeves for stress control, insulation, and screen-ing provides a location for the shield break at the end of the joint.

Outer Sealing:The cable oversheath is replaced with a thick-wall heat-shrinkable insulating sleeve, which provides the required dielectric strength and create an effective water seal and corrosion protection.

Elastomeric Technology:Two dual-wall, heatshrinkable elas-tomeric sleeves shrink rapidly and deliver pre-engineered, uniform layers of thick insulation. The outer layer shrink to the pre-determined diam-eter and the elastomeric inner part confi rms tightly to the joint.

The joint consists of connector (1), cable adapters (2) – including stress cones and main joint body (3) – con-taining Faraday cage (7) and outer serving by heat-shrink technology (9,12). The conductors of the cable are connected by a mechanical connec-tor sleeve (1) using torque controlled shear-off bolts. The connector sleeve is suitable for stranded aluminium and copper conductors but can be easily modifi ed to accept solid conductors as well. The Si-rubber cable adapters (2), accommodating the various cable insulation diameters, build up the connection area to an almost constant diameter. This allows to cover dif-ferent cable cross-sections with just one main insulation joint body (3). Therefore cross-section transitions are possible without any extra compo-nents.

No extra tooling is needed to push-on the Si-rubber cable adapters (2) and the Si-rubber joint main body (3) due to its excellent elasticity.

A metal shielding clamp (7) on top of the connector ensures perfect heat transmission and a smooth interface fi t. The fi xing rings (6) keep the cable adapter and the cable dielectric in position.

During the installation the main body is parked on the over sheath of the cable. This keeps the cut back length and cable preparation time as short as possible. Mechanical solderless con-nector technologies (8) are used to connect metal shields – copper wires, metal sheath and CAS. Heat-shrink technologies (9,12) replace the cable serving and the moisture barrier. The joint concept is similar for the shield break joints, despite the shield continuity.Special sealant components make it possible to use double-insulatedground leads, and thereby to utilise the proven heat-shrink technology.

Application:

Add-on kits for HV cables with integrated glass fi bres are available for all Raychem 145 kV terminations and joints. The add-on kits include all required components to reliably seal the cable and the glass fi bre outlet as well as suitable tubes to protect the sensitive steel pipes carrying the glass fi bres. The standard kit can be used for cables with up to two individual steel pipes. Glass fi bre splicing kits may be included in the add-on kits as well. These kits are able to handle up to 12 individual glass fi bres per steel pipe. The commonly used FOSC 500 splicing kit is able to take two steel pipes so up to 24 glass fi bres can be spliced with this splice box. The box is isolated and is therefore suitable for cross bonding joints as well.

The glass fi bre outlet is arranged straight, which means the pipe doesn’t need to be fold back. This saves the pipe from being snapped off because it’s smallest permitted bending radius usually is bigger than the diameter of the power cable.

Installation, Training and Supervision

Tyco Electronics Raychem is an independent supplier of HV cable accessories. We provide our products world wide to– utilities having their own installation

crews– contractors providing installation

services to utilities and industrial customers

– cable manufacturers

We are able to offer following services:– Installations (accessories only)– Trainings (on-site and in-house)– Supervisions

InstallationsTyco Electronics has got well trained and experienced jointers which are able to carry out installation at construction sites. Usually they are supported by local helpers provided by the contractor or the local utility.In case there are no trained jointers available locally ordering installation services from us is the fi rst choice.

TrainingJointers with 5 years or more experi-ence in HV cable preparation may be trained on-site during an installation. Less experience jointers should be fi rst trained in our labs. In both cases well experienced supervisors demon-strate how to install our products in order to ensure the high performance expected to be enjoyed over the whole life time of our products.At the end of the training the jointers will be able to carry out installations without or at least with a minimum of help provided by our supervisors.

SupervisionJointers, which have been trained by Tyco Electronics supervisors prior to an installation but haven’t yet got suf-fi cient on-site experience in installing Tyco Electronics accessories, may need the help of a supervisor on-site. We recommend ordering this service for the fi rst installations. If ensures that all accessories are installed ac-cording to the instructions provided with the accessories.

For the installation of the cable accessories the construction side must be prepared before. The installation requirements for the different products are described on the following pages.

41

Installation Requirements

Cable accessories from Tyco Electron-ics Raychem GmbH are very reliable in service and offer a long maintenance-free life cycle.

In order to assure both the installation has to be carried out as described in our installation instruction.

In addition to the process steps de-scribed in our installation instructions we recommend following commonly accepted installation practice.

General

Joints EHVS

Minimum requirements for the installation

• Access to installation site for motor vehicles / lorries.

• Complete readiness of cable routing.• Joints may be directly buried (i.e. in

a concrete tray) or installed in man holes. The size of the concrete tray or the man hole should be 4 m x 10 m in order to allow the joints to be staggered. In case the joints are to be installed in-plane then size may be reduced to 3 m x 5 m

• Cables to be jointed shall overlap by at least 2 m. Please consult the relevant installation instruction for details.

• Temporary electric lighting at the installation place (spot lights and fl uorescent lamps)

• Free power sockets 230 V, min. 10 A• Ambient temperature at installation

place shall be 15°C min. In case of lower ambient temperature, gas or electric heaters are required.

• Two or more helpers per installation team

• Taking into account the technical complexity of accessories and their installation procedure we strongly recommend installations to be carried out and supervised by well trained and qualifi ed installers only.

EHVS Installation

The sketch besides shows an example for a concrete shelter in which the joints have been staggered. The cable is laid in a cable ducts installed on metal poles of several meters height

Cable laying and jointing in a concrete duct.

Introduction

Tyco Electronics Bowthorpe has been manufacturing surge arresters for over 60 years. Our knowledge and experience we use to develop our surge arrester range today.

Tyco Electronics is well known for their insulation and protection products worldwide. The range of HV surge arresters up to 550 kV and line discharge classes from 2 up to 5 operates in 130 countries in diverse climates from the artic circle to the tropics.

Since 1988 Tyco Electronics have designed the patented series parallel metal oxide surge arrester which is special in construction and provides many advantages over conventional single column and multiple columns porcelain and polymeric housed arresters. They were designed and tested to meet defi ned abnormal service conditions as detailed in Annex A of IEC 60099-4 (1991).

The special construction of this series parallel surge arrester provides electrical and mechanical properties that cannot be obtained with single or multiple column types. In particular the geometry and unitary construc-tion provides inherent voltage grading that does not require additional grading rings or further correction of the maximum continous operating voltage (Uc) required for arresters of conventional construction.

For voltages up to 220 kV Tyco Elec-tronics offers two types of Polymeric Single Column Surge Arrester which also have their benefi ts based on the construction and design.

Application

This range of Silicone Rubber housed surge arresters is applicable for sub-station equipment and transmission lines. Because of their high cantilever strength, they can be used to replace the cable support insulators on HV terminations. This results in simpli-fi ed installation for HV terminations at reduced cost which is aestheti-cally more acceptabIe to the general pubIic.

Benefi ts

• Low residual voltages• High protection margins• High TOV performance• Inbuilt stress grading along the full length• More effective grading per unit length than a single column type• Similar stress distribution like single column type, but without stress grading

ring• Resistant against Radial stress based on the gap free Bowthorpe patented

construction• Safe non-shattering short circuit behavior to higher current levels• High-energy handling• Direct molded housing to prevent moisture ingress• Hydrophobic and tracking and erosion resistant silicone housing• High pollution performance• Excellent cantilever and tensile performance• Excellent mechanical, vibration and impact withstand capability• Extremely strong mechanical strength• Low thermal ageing of varistor insulation• Smaller footprint than equivalent single column SA with grading ring• Modular design for quick installation and commission• Light weight• Capable to withstand seismic condition• Uniform current sharing• Maintenance free• Tested in accordance with IEC60099-4 at independent accredited

laboratories• Quality design and manufacturing, ISO 9001 and 14001 compliant

52

Design Concept

Many 1-column porcelain housed and non-integrated polymeric housed type surge arresters have some limits. A few of them are the control of uniform stress grading and the radial fi eld strength which are the most important issues in these surge arrester design types. The high radial fi eld would lead to discharge in the surge arrester enclosure between the porcelain inside and the metal oxide varistors.

I. Single Modules for Single Column and Series Parallel Surge Arrester

A. Construction

The Tyco Electronics Bowthorpe patented surge arrester construc-tion eliminates the air gap by direct moulding of the silicone rubber hous-ing onto the wrapped ZnO varistor elements and the terminal assembly. The applied ZnO varistors ensure a very good electrical behaviour. The polymeric housing and the shed form (fi gure 1a) shows a good performance in salt-fog tests.

B. Housing material

Housing material is a service proven formulation of Silicone Rubber. The silicone housing was developed using the knowledge accumulated over 35 years of internal Tyco Electron-ics materials science expertise and experience, resulting in an optimum shed profi le and a material with excel-lent tracking and erosion resistance. This range of Silicone Rubber housed surge arresters has been fully tested to meet the very severe pressure- relief tests.

C. Application

The advantages of the construction and the housing material are used for the Tyco Electronics Polymeric Surge Arrester independant if they are build in a single column design or in the series parallel design.

II. The Single Column Design

Tyco Electronics offers two types of single column Surge Arrester.

The construction of the arrester type HSR is manufactured with the above described modules. These arresters are available for voltages up to 132 kV as a class 2 Surge Arrester.

The type named PCA is designed as a class 3 Surge Arrester for voltages from 30 kV up to 220 kV.

III. The Module Series Parallel Design

Especially for higher voltages are some features like voltage distribu-tion, stress grading, thermal ageing, partial discharge and the weight important for the design of the Surge Arrester. Tyco Electronics developed the Module Series Parallel Design to build up the advantages for these higher voltages.

A. Voltage distribution and stress grading

The voltage distribution is largely governed by the surge arrester geometry and intermediate plates. The intermediate connection plates of the series parallel surge arresters provide additional natural grad-ing capacitance. The intermediate connection plates have stray capaci-tances which cascade and shunt to earth. Furthermore, the resistance and capacitance of the non-linear varistors also provide voltage grading.The equivalent cascade capacitance network (Fig. 1c) gives more uniform electric fi eld distribution when com-pared it with standard single column porcelain or non-porcelain house surge arrester with or without grading ring. Intermediate connecting plates assist the reduction in radial stress at extremely high voltage sections.The overall geometry of the modular surge arrester is such that both radial and longitudinal voltage stress was at an acceptable value at an extremely high system operating voltage.

B. Thermal ageing and partial discharge

An exponential longitudinal voltage grading of a surge arrester is undesir-able phenomenon for varistor disks especially for those which are in top of the Surge Arrester. Low energy ionisation of the parallel air gap due to the high electrical stress would lead to ageing and failure of the varistor insulation. It has been established that partial discharge activity in close proximity to metal oxide varistors will lead to rapid ageing and premature failure. Therefore, the conventional single column arrester requires a grading ring for the additional reasons other than uneven fi eld or thermal considerations.

Equivalent circuit network (Fig. 2a) can only handle the varistor element in its linear model either before or after the threshold “turn on” point.

For the former, varistors have high resistance and it’s capacitance that dictates the surge arrester voltage grading. Beyond the turn on point the varistors have low resistance and this dominates the voltage grading. Further more for the former case, although the varistor or varistors are seeing high stress, the equivalent network as shown in fi gure 2a, has high source impedance (Z). Under these conditions the voltage across the varistor will collapse as soon as any signifi cant current commences to fl ow.The high equivalent source imped-ance effectively limited the voltage and current that can be applied to the varistor elements located in top surge arrestor section high stress region. It is in this context that further consideration must be given to actual ageing mechanism.

Thermal ageing of the varistor would be caused by the lack of self limiting under the combination of high stress and low source impedance. The series parallel surge arrester design has eliminated both, thermal and partial discharge ageing to the metal oxide arrester.

The Series Parallel surge arrester has no internal air gaps and therefore requires no grading ring to avoid internal ionisation.Figure 2b shows the coaxial circuit approximation model and fi gure 2c shows typical results obtained and confi rmed the near uniform longitu-dinal voltage stress distribution. The Series Parallel surge arrester does not require external means such as grading rings, to aid the voltage distribution.

C. Comparison between seriesparallel and single column design

There are differences and similarities between the fi eld plot to a standard single column porcelain house surge arrester and the Series Parallel design. They are summarized as follows:• The Series Parallel arrester has more

effective grading per unit length than the single column type

• Specially a Series Parallel 4P type exhibits similar stress distribution to the IEC example calculations, but without use the oversize diameter voltage grading rings

• Radial stress is an issue for many por celain housed design due to the inbuilt air gap between the varistor and the housing inner wall but not for the gap free (integrated housing) Tyco Electronics patented construction

D. Series Parallel surge arrester electrical tests

The following standard IEC routine testing for every series parallel surge arrester units:– Reference voltage measurement– Partial discharge measurement– Leakage current measurement– Residual voltage measurement

In addition, a proprietary internal procedure was introduced to check the current sharing of parallel columns within a series parallel surge arrester. A proprietary process ensures that between parallel columns the lowest practical differences in characteristics can be employed in one complete se-ries parallel surge arrester. Therefore, residual voltages, energy absorption and heat dissipation are shared among the parallel units.

E. Installation and maintenance ad-vantages of the series parallel design

• Good stress grading without the need of oversize grading ring

• Light weight – no heavy lifting equipment is required for installation

• Light weight – no heavy duty foundation is required for the surge arrester

• Modular design – quick installation and commission

• Lattice structure – exceptional strong mechanical strength

• Non shatter of the surge arrester housing – transportation easiness

• Non shatter of the surge arrester housing – no damage to personal and nearby expensive equipments

• Good pollution performance – maintenance free

• Environmental acceptable material – maintenance free

The series parallel design is capable to withstand seismic condition set in the current international standards which warrants reliable maintenance in all regions.

Transmission Line Surge Arresters – TLA

Lightning is responsible for approximately 65% of all of the non-scheduled out-ages occurring on transmission lines.Power supply utilities have verifi ed the load losses due to voltage sags in their systems from transitory outages caused by lightning activity and in some regions they have found serious permanent damages on important lines.

The effect of transitory disturbances on transmission lines can also be more critical in areas with high ground resistivity when associated with high lightning activity.

Although a fault time is shorter than 1 minute, in many cases this is still unac-ceptable. This loss of supply is critical for all modern industries, electronical equipment and especially production processes.

In most cases line arresters (TLA), electrically connected in parallel with the insulating string, have been considered as the most effective method currently applied to improve transmission line performance, especially when associated with improvements of the grounding system and usually presents the best benefi t versus cost relationship in reducing fl ashovers of the insulator string due to excessive voltages.

Features & Benefi ts

• HV arrester suspended from a transmission line giving enhanced transmission line performance

• Increasing system line voltage on standard insulated transmission lines

• Minimising circuit breaker opera-tion with possible system outage resulting from back fl ashover on the transmission line

• Switching overvoltages are ab-sorbed over the length of the line reducing the severity of surge at the substation

• Transmission systems can be oper-ated even where sub-soil gives poor tower footing resistance

• Eliminating interrupted power sup-ply for sensitive industrial processes

• Installing TLA on a standard 3 phase voltage system along the line, at cal-culated intervals, allows for optimum performance of the TLA, to give an increased system line voltage. Therefore eliminating the need to increase the standard insulation level required on conventional system upgrade.

Surge Counters – Type SC 12 & SC 13

The Tyco Electronics Bowthorpe EMP range of Surge Arrester monitoring in-struments are fully tested for use with any manufacturers surge arrester. The SC 12 is a Surge Counter only, whilst the SC 13 provides the additional measurement of total leakage current. The analogue instrument provides a means of monitoring the current through the arrester and the leak-age current over the surface of the arrester housing. Signifi cant changes after installation may indicate a deterioration in the arrester or a build up of surface contamination.

These instruments, which require no auxiliary supply, are designed for installation in the earth connections of a single surge arrester or alternatively the SC 12 may be used with the com-mon earth of a three phase set.

Fully weatherproofed and sealed for life they are housed in a one piece gravity die cast aluminium case coat-ed to enhance its already high degree of resistance to surface corrosion. The glass viewing window is sealed in place, using a silicon rubber adhesive, and a desiccator is enclosed to ensure any residual moisture trapped during sealing is absorbed for the service life of the counter. Mounting is effected by means of an integrally cast lug at the rear of the case providing a single clearance hole for the galvanized steel M 12 bolt supplied.

The SC 12 and SC 13 are service proven and require no special mainte-nance or servicing apart from general cleaning of the glass viewing window and the moulded epoxy resin line bushing.

Introduction

Construction

Tyco Electronics Tension Insulators were built as composite insulators. They are based on Raychem’s 30 years experience in the fi eld of crosslinked polymers for medium and high voltage applications. They consist of a polymeric housing of ethylene vinyl acetate (EVA) over pultruded fi berglass rod to which galvanized steel or aluminium end fi ttings are attached. By molding directly over the end fi tting, or by using a track resistant polyurethane, moisture ingress to the fi berglass rod is prevented.

Composite Insulators are available for applications up to system voltages of 72 kV. They provide a reliable solution for power utilities and railway com-panies with installations in severely polluted environments all over the world.

The core of a composite insulator is a pultruted fi ber glass rod which provides a high mechanical strength. In a direct injection molding process a non-tracking, erosion and UV resistant polymeric housing is molded directly onto the fi berglass rod. A corrosion resistant metal fi tting is crimped onto each end to the rod to provide a high mechanical strength. A new developed crimping control technol-ogy monitors the assembly process of the metal fi ttings and ensures that crimping forces cause no damage to the fi berglass rod while achieving a crimp that will withstand extremely high mechanical loads. Sealed with a tracking and erosion resistant poly-urethane barrier, the core is protected from deterioration due to moisture ingress.

Application

Composite insulators are available as tension (suspension), line post and station post insulators. For railway applications, tension and strut composite insulators are available in a large variety of confi gurations.

The maintenance free characteristics of Raychem’s EVA material have been demonstrated during service expe-rience of more than 30 years.

The Tension insulators are qualifi ed to the requirements of the IEC 61109.

New products up to 230 kV

A range of High Voltage silicone ten-sion insulators from 69 kV to 230 kV will be available shortly. These insula-tors will cover normal, high and extra pollution levels. They will be available with a variety of end fi tting options, ball, socket, eye, clevis, tongue and Y-Clevis. They will also available with corona rings where required.

Vibration Dampers

General RecommendationsVibration dampers are designed to eliminate conductor fatigue damage and line maintenance costs by ef-fectively diminishing aeolian vibra-tion, thereby allowing increased line tensions.

All Tyco Electronics damping devices are designed for the single purpose of reducing vibration. This unitary func-tion is entirely different from that of protecting against: (1) stress concen-trations, (2) fretting of abrasion and (3) arc-over burning.

Stockbridge Vibration Dampers Dogbone Vibration Dampers Spiral Vibration Dampers

The Stockbridge vibration dampers are constructed with a 7 strand mes-senger cable to improve the damping. Damper weight and length will be optimized for maximum effi ciency.

The Dogbone vibration dampers are constructed with a 19 strand mes-senger cable to improve damping and fatigue performance. The design of the zinc weights eliminates water entrapment. The messenger cable has improved energy dissipation at low amplitude of fl exure.

Spiral Vibration Dampers are ex-ceptionally effective against high frequency aeolian vibration of EHS or Alumoweld shield wires.

Spacer Dampers

2 Bundle Posilok Spacer Damper

Spacer Dampers are recommended for multi-conductor bundles with industry standard spacing. The Spacer Damper is designed to withstand the forces and movements caused by transient conditions such as short circuit, differential icing, and wind loading without either causing dam-age themselves.

3 Bundle Posilok Spacer Damper

The design accommodates both longitudinal movement of the subcon-ductors, vertical sag differences, as well as compressive and tensile forces.

The Spacer Damper can constitute a system which replaces conventional spacers and vibration dampers.

4 Bundle Bolted Spacer Damper

Spacer Dampers will control both Aeolian vibration and subconductor oscillation to levels recognized as acceptable within the industry and to the customers expressed needs. Tyco Electronics will tailor the recom-mendations to terrain and design parameters.

Posilok Spacer

Posilok spacers are designed to main-tain specifi ed subconductor spacing. Furthermore, they are designed to withstand the forces and movements caused by transient conditions such as short circuit differential icing and wind loading without either causing damage to the subconductors or sustaining damage themselves.

The Posilok spacer is fl exible enough to allow some longitudinal movement between subconductors and yet rigid enough to restrain the subconductors under adverse conditions. They pro-vide a smooth, unitized construction which minimizes corona and presents a low level of RIV.

95

Suspension Clamps

Heliformed Suspension Unit Forged / Cast Bolted Suspension Clamp

Suspension clamps are designed to reduce the static stresses at the sup-port point, as well as insure that the conductor is cushioned against the dynamic stresses of aeolian vibration. They also protect the conductor in the support area against impulse and power fl ashover.

Dead Ends

Wegde Tension Clamp Bolted Tension Clamp

Dead Ends are designed to fi x the transmission line at the pole. There are two possibilities to fi x the cable into the Clamp: the wedge and the bolted solution.

Compression Fittings

Full Tension Fittings

Full Tension Fittings are designed to hold a minimum of 95% of the specifi c conductor breaking load.

Non-Tension Fittings

Non-Tension Fittings are designed to hold nominally 10% of the conductor breaking load.

Spacers

Spacers are designed to maintain conductor separation.

The neck diameters and groove height dimensions appear in ANSI Standard for low and medium voltage pin type insulators and also at the beginning of each listing.Ties are recommended as an improve-ment over Armor Rods secured with hand tie wire.

Ties are available as:– Longspan Ties– Distribution Ties– Double Support Ties– Side Ties– Double Support Ties– Spool Ties– Quick Spool Ties

Splices

Splices are designed for joining ACSR or repairing ACSR when damage to the core is suspected. Full Tension Splice will hold the full rated breaking strength and restore conductivity.

Conductor Splices are designed as a single component outer layer as-sembly for sub-EHV conductor. All conductors, new or weathered, must be thoroughly scratch brushed until bright and clean and an inhibitor ap-plied immediately prior to installation of the splice.

Armor Rods

Armor Rods are intended to protect the conductor on which they are being applied against bending and compression stresses, abrasion, and arc-over. The degree of protection needed on a specifi c line depends upon a number of factors such as line design, temperature, tension, exposure to wind fl ow, and vibration history on similar construction in the same area.

Armor Rods should be considered as minimum protection for clamp style supports of bolted suspension arrangements.

Armor Rods do not act as vibra-tion dampers. They are designed to provide an extra degree of protection to the conductor at support points.

Line Guards

Line Guards are intended to protect the conductor against abrasion and arc-over and to provide repair. The degree of protection needed on a specifi c line depends upon a number of factors such as line design, tem-perature, tension, exposure to wind fl ow, and vibration history on similar construction in the same area.

Line Guards are recommended as minimum for use with hand-tied spans of less than 300 feet in urban construction having no experience of vibration. Line Guards alone are not recommended for use in areas of suspected vibration. They are designed to provide an extra degree of protection to the conductor at support points.

Heliformed Suspension Unit

Heliformed suspension is intended for use on aluminium based conduc-tors, alumoweld and galvanized steel strands. They are designed to reduce the static stresses at the support point, as well as insure that the conductor is cushioned against the dynamic stresses of aeolian vibration. They also protect the conductor in the support area against impulse and power fl ashover.

Although Heliformed suspension pro-vides improved protection over armor clamp or bare clamp attachments, in the case of known vibration, vibration dampers will be necessary. Consult Tyco Electronics for recommenda-tions concerning Dogbone vibration dampers.

Fiber Optic Dead EndFor ADSS cable

Fiber Optic dead ends may be installed once as a temporary (less than 30 days) pulling device prior to its fi nal installation; as long as it is not stressed over 50% of its rated strength.

The dead ends are sold as an assem-bly including reinforced rods, a dead end, clevis thimble, extension link and oval eye nut.

Fiber Optic Dead EndFor OPGW cable

The fi ber optic dead end may be installed once as a temporary (less than 30 days) pulling device prior to its fi nal installation; as long as it is not stressed over 50% of its rated strength. A ground clamp may be ordered with the dead end. Clamping over the OPDE or the OPRR assem-blies is not permitted.

Maximum Rated Holding Strength is 95% of the OPGW RTS.

Optical Tension Device (OTD)For OPGW Fiber Cable

Tyco Electronics’ new Optical Tension-ing Device is designed for pulling OPGW fi ber cable to fi nal sag tension. Once the fi nal sag has been achieved, a permanent type dead end device should be installed promptly, followed by the removal of the tensioning device.

This device should not be subjected to sag tension for an extended time period and it should never be utilized as permanent dead end device.

Fiber Optic Suspension Units

The fi ber optic fi xed suspension unit is a low cost assembly for installing ADSS cable. The aluminium housing is joined with stainless steel roll pins, which ensure positive alignment. The housing is cushioned on the inside with an EPDM liner which is specially sized to provide excellent slip strength ability and yet not impart any undue clamping stresses on the cable.

A grounding lug, consisting of a 10 mm aluminium bolt tapped in the housing, is available as an option.
