HV copper transmission conductor with hollow inner strands?
HV copper transmission conductor with hollow inner strands?
(OP)
Hi there;
We've got some 1940s era copper phase conductors (500 MCM) up on a 230 line that have solid CU exterior strands but hollow CU internal strands. Nobody really knows anything about it, so I was hoping to see if any Eng Tips users are familiar with this conductor. Maybe have a spec sheet from the original manufacturer?
If it helps, we've got other older copper conductors in different parts of the system including the Anaconda twisted I-beam.
Thanks in advance.

The stuff we have is generally just a stranded copper cable, but the individual interior strands are each hollow. I just found an old brochure that clears up the mystery, though!
The conductor is called "Phelps Dodge Copper Products", or P.D.C.P., Hollow Conductor. I'll try to post it once I get the scan done.
