Ah ok, yes that would need to be insulated!  I don't think we have cables 
like that anywhere here (or if we do it's really uncommon), it's all 
underground apart from the high voltage long distance stuff.  I remember 
when I visited Japan they had crazy amounts of cable in the air, with 
transformers at the top of poles etc, I'd never seen anything like it:

I guess once you start putting power and telephone above-ground, things get 
very messy very quickly in heavily populated areas.  Underground I suspect 
you have the same, it's just hidden from sight!
