Why not consolidate all your questions into a single, multi part request for help?

Is this your first power line?

Sounds like you're in deep doo-doo.

Care to expand on "yes"? Maybe someone here could help, but we need to know more.

Oh dear, if you have to ask these questions you are going to have a difficult job. There should be a code that governs your work. Here in the USA, back years ago when I worked on these, it was governed by the National Electrical Safety Code. Perhaps you can get a copy of this code, it looks as though it is still extant.

NESC Standards

Sorry I can't help more, I was delighted to forget all about it when I got back to real structural work.
