The JIAHE connection mould is designed to last for an average of 100 connections. This will vary according to the care given the mould during use.
Exothermic Welding Powder: qualified by national authority test department-"WHVRI" with the Inspection report, only in China.

Exothermic Welding Powder:
The capacity of an earthing circuit to protect the safety of personnel depends on the quality of the connections made .
JIAHE exothermic welding is RENTONG ' s patent product in China . And it has the best quality in China as the same product in U.S.A. and U.K . So JIAHE Exothermic welding powder is qualified by national authority test department Wuhan High Pressure Research Institute State Power Corporation of China with the testing reports . JIAHE is the only one who obtains this testing report at the present time .
The principle of the exothermic welding consists of bring together a welding filler material and ignition agent in a suitable graphite mould. The shape of the mould, its dimensions , and the size of the weldmetal , are all dependent on the item to be welded and their size .

 

The Exothermic Welded Connections are made using the high temperature reaction of powdered copper oxide and aluminium. The process is a simple, self-contained method of forming high quality electrical connections which requires no external power or heat source.
 Exothermic Welded technics reaction equation is as follows:
