    It looks like 3 phase power cable to me. My guess is that it is not run very far.

    must be power cable.

    Data cables have been fiber optics for decades.

    I think it's fake. They had one on Gilligan's Island once, and it looked nothing like this.

    What do you mean sense of humor? I saw that episode and he’s right!

    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.

    Based on the core insulation I would think they are running in the low to mid-Khz range to be effective for the primary phases. But that is some serious amps...likely a lower voltage. 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.
