Brazing Copper Earth Tape

Brazing Copper Earth Tape

Brazing Copper Earth Tape

(OP)
The spec is that all copper earth tape joints must be brazed. Fault level is 15kA. Size of tape is 50mm x 6mm (300mm²)
What should the joint overlap measure and what is the best filler material to use to gain optimum strength and conductivity? Would a butted "T" joint be acceptable IE contact surface 300mm².
Comments very much appreciated.

RE: Brazing Copper Earth Tape

How about an exothermic weld? They can be made with full overlap or a butt connection. See http://www.erico.com/catalog/cadweld/
and select "Bus bar to Bus bar". They make molds for 50mm x 6mm bus.

Thanks Alehman, Yes I've used this kind of joint on buried tape joints. They are very good. But if you've got a client etc who wants the joints brazed, well you have to do it. I need to know what is used as the most cost effective method.
Type of gas torch.
Type of flux.
Type of filler.
temperature etc.
Types of joint etc. etc.
