Power Line Cable Wire

Might be the wrong spot to ask this question but since I spend the majority of my time here I thougt I would ask anyway. A customer that I mow for has a newly built home. I noticed some powerlines down. Upon inspecting there is approximately 200-250 feet of very thick wire wrapped around trees and still tied to poles. The cables are very light and looks to be AL (I did a scratch test as well, not copper). Any idea about how much weight in that much wire? Any dangers involved?

Illegal to take it. If it is attached to the pole it belongs to electric company.

You don't want that wire anyway. Unless it has copper it will take a heck of a lot of it to make good cash.

Theres probably a single steel wire inside it anyway.
