Thanks again for your contribution, Steven.
I'm hoping to provide as much context and thought process as I can, so that the question and its context will be clear to translators who view this page.

Well if you're going to fight with me I don't see the purpose in doing the research work for you.

Thanks for the suggestion, Steven.
I had thought about polyethylene, but that means the tecnico P.E. is a "polyethylene technician". "Tecnico cavi" would seem more logical if that's what it means. Same for the "armadi e piantane P.E." They could be made of polyethylene, but you wouldn't really call them that, would you?
Additionally, polyethylene is usually pe without the dots, which makes me think that P.E. in this context means something else.
