Those, say for 0000 and bigger, on up to 750 mcm, have always been std bronze stuff unless it was the local power company, whom I gave pure hell after the third burnup on Fisher Hill in 15 years because they were using an ALU sleeve in a Burndy HyPress to join the substation cable, 600 mcm alu, to the copper 750 mcm going into the building weatherhead. Over the life of WDTV on that hill, they had cut the weatherhead cables back to make a clean spot to re-crimp, so close to it that the heat telegraphed into the weatherhead riser the last time and burned it to about 4 feet down in the conduit and we had to replace that 10 feet of 4", the weatherhead, and 4 pieces of 750 mcm about 20 foot long ea to get us back on the air the last time. Pure, unabashed stupidity on the part of the power company crew and I blew up. And got informed they were following orders. And when going after repairs, I have never been offered a thing with any springs in it, just those little tubes of deoxit (sp?) grease to seal the air out. If I ever have to do that again, I'll definitely ask. IMO, the present situation vis-a-vis alu wire and how it is terminated according to the NEC here in the states, should be grounds for criminal proceedings when it causes life or property loss.
