Steel is about 10 times less conductive than copper which is why it is rarely used for cabling. Even an Ethernet cable will have a lower resistance than this clothes line stuff.

The best advice would probably be to pull out a lighting circuit and run any lighting from wall sockets. Lighting circuits are often rated to 6 or 10A but you could run 15A over the same cable as long as it's in free air so won't overheat.

Unless the ethernet cable is made from copper clad steel, which is sometimes used for ethernet cables and very common for consumer grade phone and RF cables.

I've heard of copper clad aluminum but never copper clad steel Ethernet.

It's actually pretty cool - it's very flexible and convenient.

It's difficult to solder and impossible to crimp though (so we use these factory-made), and I would not use PoE with it (the gauge - 32AWG - also means that it is really thin, and as it's steel, the resistance must be terrible. But for data, it works good.)

Well, iirc the classic coax for cable TV is that; they may use solid copper when using it with an LNB to power said LNB.
