(OP)
When did other utilities stop installing copper wire as an overhead conductor? I'm guessing it was some time after WWII, but that's just a guess.
I have a similar question about the use of copperweld. I think we stopped installing that after 1945.

Following up David's comment, I visited Hoover Dam a few years ago and obtained few inches of an original transmission line material from the gift shop that looks like what you describe. It has interlocked segments forming a hollow cylinder. Looks very expensive to manufacture.

I have a photo somewhere of copper-clad switchgear at 'Boulder Dam'. I can only imagine this was because of high eddy current losses in steel. Do you know if that is still there - I've never seen anything like it. I'll scan the image and post it when I'm back in the office.

There are some really interesting picutres in that book, although I should probably post them in the Engineering History forum rather than drag this thread any further off course.
