The Exothermic Weld Process4
Exothermic welding is a cost efficient method of making large or small numbers of high quality electrical connections. It is a simple,self-contained system that uses the high temperature reaction of powdered copper oxide and aluminium, within a mould, to form permanent electrical connections.

 

Typical applications include:
1.Earthing for power plants and substations
2.Telecommunications
3.Transmission and power distribution lines
4.Cathodic protection
5.Rail connections

The Exothermic weld system:
1.requires no external power or heat source
2.creates high quality electrical connections
3.is completely portable
4.can be used safely with minimum training
5.is cost effective
6.can be used for over 70 standard connection configurations

 

The Exothermic weld connection5

Exothermic weld connections have several advantages:

1.tolerant to repeated fault currents

2.highly conductive

3.do not loosen

4.excellent corrosion resistance

Most Exothermic weld connections have at least twice the cross-sectional area of the conductors being joined, and an equivalent or greater current carrying capacity. Corrosion resistance is exceptional because of the very high copper content (> 90%) of the alloy.
