It probably has to do with being able to lay it out and take it up which they do frequently. They don't worry about skin effect with Stranded wire at 60 Hz.?

Interesting, that still allows fairly large cables. I read somewhere that the people that run power from those large generators used on remote movie locations and stage lighting setups run parallel wires for each power leg, rather than a larger single wire for each. I wonder if that (skin effect) is the reason. Or is it just that larger wire is not available for the high currents they are working with.?
