I have seen pieces of power cable for transmission lines that was hollow.



What did they do to keep the stranding from collapsing inward?

The strands were ribbon shaped and the edges were a locking "tongue and
grove" arrangement.
I do not know how it was assembled but the individual strands could
slide, making it fairly
flexible. The piece I saw could be disassembled and re-assembled.

I read of one power company that pulled fiber optic cable inside their
power line. That optic
cable was for communications, not power :-)
