Typical examples of application of helical fittings for attachment and repair of OHL conductors and ground wires

JSC "Electrosetstroyproject" (JSC ESSP) was established in 1991 as a research-and-production enterprise

with the basic line of activity including design and manufacturing of helical fittings for attachment and repair

of OHL conductors and self-carrying optical cables.

In 1992, the JSC “ESSP” mastered production of helical fittings for attachment of self-carrying optical cables

of type ADSS and OPGW on overhead transmission lines.

Since 1995, the JSC “ESSP” produces in industrial scale the helical fittings for attachment and repair of

conductors and ground wires of overhead transmission lines.

Armor rods (ARH), helical suspension clamps (SH), helical dead-end clamps (DH), mid-span tension joints

(TJH), helical non-tension joints (JNJH), helical repair mid-span tension joints (RTJH); multifrequency

vibration dampers (VD); intra-phase spacer-dampers (SD) are widely applied.

Repair the conductor ACSR-400/51 with the mid-span

tension joints TJH. The construction consisted of:

- a connector made of galvanized steel helical rods of 0.9 m

lengthforstrengtheningtheconductorsteelcore;

- 3 current-conducting layers of lengths 1.3, 1.7 and 2.5 m

respectively;

-armorrod-clamp-2.4m.

It enabled to completely restore current-conducting properties

of the conductor and equally its mechanical strength.

2003

Repair the conductors ACSR-300/39 on OHL 500 kV “the

Balakovskaya nuclear power plant – the Substation Trubnaya”

2007 FOCL-OHL “Chelyabinsk-Khabarovsk”During construction of FOCL-OL, ESSP developed and applied new technology of replacing a ground wire to OPGW, in particular on metal support structures of OHL 220 kV on live-line. The technology essence consists in the following. Fixing and traction ropes are moved on the old ground wire by means of traction radioguided device and double fixing rollers. OPGW is then pulled and the old ground wire is removed. For safety of the works on replacement of the ground wire to OPGW, the system of traction and brake complexes, devices, and mechanisms are used. Test installation of OPGW on live-line was presented on a testing area for commission acceptance of PC FSK EES. The acceptance certificate was accordingly approved and signed. Training was delivered for the maintaining and engineering personnel in the educational center. The live-line technology at OPGW installation was successfully applied by construction-mounting team of ESSP on the North Baikal site of the OFCL-OL "Chelyabinsk-Khabarovsk" of about 100 km on the double circuit line 220 kV.

2009 Reconstruction of OHL 220 kV "Afipskaya-Crymskaya" The high temperature conductor GTA CER217/49 J-Power SystemsA conductor replacement on OHL 220 kV "Afipskaya-Crymskaya" has been performed by the ESSP company in the Transmission Electrical Networks of the South. The reconstruction has been done in a difficult mode of daily energizing the line and switching it off for evening and night time.The target of increasing the conductors current caring capacity for more than 20 % was fixed for JSC "ESSP" on the single circuit transmission line 220 kV "Afipskaya-Crymskaya" of about 70 km length, which was put into operation in 1960.Consideringthatfactthatthesupportstructuresweredeterioratedforcertainlevel for years of operation, the JSC "ESSP" prepared the design solution in which the substantial increase of the current caring capacity and reliability of OHL is achieved by replacement of the conductor on the existing support structures with the progressive gap type conductor with the raised capacity and improved mechanical characteristics.The gap type conductor has smaller weight, diameter and at temperature growth with current increase, has a smaller sag, than the traditional conductor ACSR 300. The JSC "ESSP" used the special tools, mounting equipment, and also special methods for installation this unique conductor.

2009Repair of the conductor ACSR-300/39 on OHL 220 kV Thermal Power Station-Vostochnaya with the non-tension joints JNJH -24,0-53.

In case of use of the helical repair mid-span tension joint TJH-D-21 it should be noted that its application for conductor with 100%

aluminium damage is permitted only when the conductor with such damage wasn't yet under current loading, but it was damaged

during emergency (for example support falling). If the conductor with 100% aluminium damage was already under current loading,

mechanical strength of the steel core can appear reduced because of its possible local overheat. Therefore this design can't provide

necessary mechanical strength of a helical repair sleeve. In this case it is recommended to use the helical repair sleeve TJH-D-31,

which enables to restore mechanical strength of the steel core. The design of such helical repair sleeve is similar to the structure of

TJH-D-11 and consists of a connector and one or two conducting layers.

TJH-D-31 if for repair of conductors in case of about 100% damage of aluminium wires and about 20% damage of steel core wires

(no more than 1 wire for 7 wires cores, no more than 3 wires for 19 wires cores, no more than 7 wires for 37 wires cores).

Helical armor rods ARH-D-ХХ for protection of OHL conductors

General The helical armor rods ARH according to theSpecifications3449-007-27560230-06aredesigned for additional protectionofconductors and ground wires from vibration in suspension clamps and mid-span tension joints, multiroller suspension clamps on OHL crossings, and also for additional protection of the aluminum hollow conductors in lugs.Using the helical armor rods at the area of a suspension clamp or a vibration (galloping) damper on a conductor enables to lower essentially the flexural (static and dynamic) deformations in the conductor at the expense of increase of its flexural rigidity and to increase its fatigue durability for long operation.Helical armor rod is a set of separate helices or glued strands, twisted on conductor surface. Helical armor rods can be made of lengthfrom500mmto6300mmforconductorsfrom35mm2to640mm2.LabelingHelical armor rods labeling:ARH –helicalarmorrods;D –conductordiameter,mm;two last figures – purpose and modification of helical armor rods.LabelingHelical armor rods are manufactured in the temperate and cold climate modification of Category I. ModificationsThe following types of helical armor rods are manufactured:ARH-D-03 – for decreasing flexural deformations of conductors caused by vibration and for alignment of squeezing forces from fastenersinthesuspensionclampsSBR-5andSBR-6,andalsounderthevibrationdampers.Lengthofthehelicalarmorroden-ables to place one vibration damper on each side of the suspension clamp.ARH-D-01 (SBL), ARH-D-03 (SBL), ARH-D-21 (SBL) are used to reduce the bending strains in the supporting clamps with limited clamping (SBL) for conductors and ground wires in OHL crossings.ARH-D-11 is used to reduce the bending deformation of cables caused by vibration and high squeezing loads in the areas of vibra-tion and galloping dampers fixation.ARH-D-13 is used to decrease flexural deformations of conductors caused by vibration and high squeezing loads in the areas of aeolian vibration or galloping dampers fixation.ARH-D-21 is used for protection of conductors from deterioration in multiroller suspensions in OHL crossings. Helical armor rods can be used for replacement of the aluminum protective sleeves SP installed in multiroller suspensions and worn out during long operation in overhead transmission lines crossings to such degree that there is a damage of conductor aluminum layers, and also in those cases when replacement is necessary because of condition of the protective sleeves SP.ARH-D-31 is used for protection of the ACSR from flexural deformations caused by vibration at the outlets of mid-span tension joints.ARH-D-43 is used for protection of hollow conductors from flexural deformations occurring at aeolian vibrations, in lugs outlets. The set includes mounting corrosion-proof tape (120 cm) and lock-clampers (3 pieces).

Recommendations about application

The spacer-dampers can be applied both for construction of new OHLs and for repair of existing OHL with conductor bundles. Installation places of the spacer-dampers should be defined so that suppression of the aeolian vibrations of conductors is most effective. For creation of protection schemes for conductor bundles, it is necessary to fulfill special calculations with the follow-ing input data: type of conductor bundle, inter-conductors distance (bundle step) for every support structure, conductor type and model, average operational and maximum admissible tension, span lengths. Using received data, the JSC “Electrosetstroypro-ject” and The JSC “Scientific and Technical Center ‘Elektroseti’” develop recommendations about application of spacer-dampers and schemes of protection from vibrations induced by wind. All recommendations are free of charge.

High temperature conductors

DescriptionThe high temperature conductors TACSR/ACS and TACSR/HACIN are designed for ap-plication on overhead transmission lines. A high temperature conductor has the property to sustain essentially larger temperature than the classical conductors, without change of its properties. Operation temperature of the conductors TACSR/ACS and TACSR/HACIN is150°С.Thehighoperationtemperatureconductorshavehightransmissioncapacity.

•WhenselectingahightemperatureconductorwithequaltransmissioncapacityofanACSR,weightofthehightemperatureconductorcanmakeonly60%oftheACSRweight. It enables to lower essentially conductor sag and to reduce loading on sup-ports;

•ThedesignofthehightemperatureconductorsTACSR/ACSandTACSR/HACINdif-fers from the design of an ACSR by the core made of steel plated by aluminum and by the conducting layers of aluminum alloy with zirconium inclusion. Designing, installation, repair, and protection of high temperature conductors don't differ from those with an ACSR.
