I'd like to have the copper from a 100 ft of those main conductors
It looks like 3 phase power cable to me. My guess is that it is not run very far.

must be power cable.Quote:

I think it's fake. They had one on Gilligan's Island once, and it looked nothing like this.
I give you an A+ for a wonderful sense of humor.Quote:

Yup. The capacitive losses over any significant distance on that cable would be substantial. If you ran two of them side by side you could have a good upgrade path to HVDC.Quote:

Early Aircraft and old navy stuff used to run at 400hz. Also interesting are the 2 conductors at 11 and 5 O'clock which appear to possibly be some form of Coax although the Braid wire is quite large or even Cu tubing?? Brings a whole new meaning to multi-conductor control and power cable.
