WHY IS LIGHTNING PROTECTION IMPORTANT?

Lightning is a natural flow of static electricity between the sky and the ground. It strikes buildings, structures, trees, livestock and persons in all parts of the world. Although it rarely occurs in some areas, it is a severely destructive hazard whose destructive force is beyond human scale.The damage from lightning comes from electrocution, human burns, burning buildings, explosions, melted or damaged electrical equipment and stresses on electrical equipment that are responsible for failures.An effective earthing system is a fundamental requirement of any modern structure or system for operational and/or safety reasons. Without such a system, the safety of a structure, the equipment contained within it and its occupants is compromised.In order to preserve resources and human lives a reliable lightning protection system must be set in place and must be taken into account during the planning stage of any project.A reliable lightning protection system intercepts lightning strikes and attempts to guide the static electic flow down a chosen path, slightly away from the people, structures and electrical equipment. It provides means to carry electric currents into the earth under normal and fault conditions without exceeding any operating and equipment limits or adversely affecting continuity of service and assure that a person in the vicinity of grounded facilities is not exposed to the danger of critical electric shock.

SEICO EARTHING AND LIGHTNING PROTECTION SYSTEM

The SEICO Earthing and Lightning System provide a dependable structure to protect resources from such hazards. We offer a products made from highly conductive materials and with high resistance to corrosion to achieve a sustainable “connection” to earth.

We provide the entirety of the devices needed in installing an effective and reliable Earthing and Lightning Protection System on or in the structure to be protected. Enabling clients to install an economical system that will intercept and discharge static electric flow into the earthing system.

Our system is composed of:

a) Interception Devices (Air Termination System)• A system designed to capture lightning strikes to a specified and selected attachment point.

b) Down Conductors• Electrically conductive connection between the interception device and the earth system directing the discharge current safely to ground with minimal risk from “sideflashing”.

c) Earth System• An essential part of the lightning protection system, the low impedance ground dissipates the energy into the ground. Minimizing the ground voltage potential rise therefore lessening the risk of injury to the occupants and damage to equipment.

d) Exothermic Welding System• Creates a permanent bond that is capable of withstanding repeated fault currents and abnormal heating due to a high fault current.

Whether you need a full Earthing and Lightning Protection System for a major construction project or you need your annual system maintenance replacement, your job will be handled with the same care and attention we give to all our work.

EXOTHERMICSEICOWELD SYSTEM

MOULD SPECIFICATION

Grounding Connection Specifications

All grounding connections of copper-copper or copper-stell conductors 10mm2 and larger size shall be

connected with exothermic welding and this is considered as a continuous conductor, as stated in the

note accompanying NEC 250-81, 250-91, 250-113, 250-115 and IEEE Standard 80-1986.

The SEICOWELD Process

The SEICOWELD exothermic welding process is a simple, self contained method of forming high

quality electrical connections. The compact process requires no external power or heat source,

making it completely portable.

SEICOWELD connections are made inside a semi-permanent graphite mould using the high temperature

or powdered copper oxide and aluminum.

The majority of SEICOWELD connections have at least twice the cross sectional area of the conductors

being joined, and an equivalent or greater current carrying capacity. Because the connection is a fu-

sion of high conductivity (high copper contect alloy) it will withstand repeated fault currents, and will not

losen in the way that mechanical connectors can. Due to the alloys very high copper content

(in excess of 90%) is corrosion resistance too.

MOULD INSPECTION & INSTALLATION GUIDELINES

The SEICOWELD connection mould is designed to last for an average of 100 connections. This will very

according to the care given to the mould during use. To determine if a mould should be replaced,

regularly inspect the following checkpoints.

CABLE OPENING•The Cable should be fit for the hole. A loose fit will cause leakage of weld powder.•The opening should not be crack or worn out.

WELD CAVITY•The cavity should be well defined.•There should be no chips or gouges.

TAP HOLE•The tap hole should be well defined.

DISK SEAT•The seat should not be worn or cracked.• The disk must seat properly.

MOULD PARTING FACE•The parting face should be cleaned by shop towel or newspaper.•Wire brush should not be used in cleaning the mould, this will cause defectand might destroy the mould.

WELD CONNECTION

MAKING OF SEICOWELD CONNECTION

When making a copper wire connection of ground rod or other material connection, put the SEICOW-

ELD powder into the graphit mould. Just ignite to start the welding process. The result will be clean and

smooth connection surface, which has been field proven. It is also applied for other metal, such as : Iron,

Steel, Railway track, Wrought and Cast Iron, Bronze, Nichrome and Bronze.

SEICOWELD exothermic welding can be used in various applications to have certainly goodsconnections in work. Many projects trust in SEICOWELD such as: •Lightning and Surge Protection•Grounding in Electrical Works•Railway Construction•Cathodic Construction•Another High Capacity of Current Supply

SEICOWELD offers different types of mould. There are “One Time Mould” and “Graphite Mould” with different shapes to suit different welding works.

“ONE TIME MOULD” is made of ceramic suitable for “One off” welding work.

“GRAPHITE MOULD” is made of high quality graphite suitable for high quality welding work and can be used for several times and which has the following advantages:• A smooth metal connection that will not loosen or corrode.• It is not affected by high current surge or over current.• No need for external welding machine.• Use only lightweight and cheap equipment.• Virtually maintenance free.

SEICOWELD ACCESSORIES

This is made of graphite block, a

heat resistance material which

normally welds an average of

70 to 100 connections under

normal size.

For safety and quick

ignition of the starting

powder. Standard flint

replacement are suitable.

(IL)

For easy cleaing of the

conductor before welding.

(CCB)

For cleaning safely the

inner part of the mould.

(MB)

For removing easily the

stages which accumu-

lated the crucible. (MS)

This is used for opening and clos-

ing the mould. The handle clamp

(HC) are of two types depending on

the mould size

(HC-M & HC-L).

For welding cables on steel pipes,

the handle clamp SHC-1 is

especially designed to fit solid

moulds.

WELDING INSTRUCTION

Step1: When using insulated cables, remove first 150mm of the isolation of the conductor and all the dust and oxydes is to cleaned properly by mould brush, and/or cardcloth brush.

Step4: Close the mould with the handle clamp and put the STEEL DISC on the taphole, the conical side of the disc should be at the bottom.

Step7: Ignite the flint ignitor from aside the ignition powder. Pull away the flint ignitor once it ignited to avoid damage.

Step2: Preheat the welding mould with a welding torch or ignite a box of weld powder in order to remove the mois-ture before starting the first weld.

Step5: Pour the weld powder, which is on the upper portion of the powder box, into the crucible.

Step8: After one minute, separate the two arms of the handle clamp to open completely the mould in order for the welded parts tube to be removed. Extra care should be taken so as not to dam-age the mould.

Step3: Connect the handle clamp to the hole and separate the two arms to open the mould, then fit the conduc-tors and leave 5-6mm gap on the other conductor.

Step6: On the bottom of the powder canister, you can see the ignition pow-der, put it on the lip of the crucible and on the top of the weld powder for easy ignition.

Step9: Clean completely the mould by using mould scraper and by mould brush,m you can continue welding as long as the mould is still warm.
