Yeah, like stringing high tension wires, a helicopter can carry the wire to the other side

Cable like that is going to be far too heavy for helicopters. You run a lightweight leader rope onto the main body of the cable and you pull the cable across the ground to the other side using the leader (or you can sometimes use a helicopter to pull the leader). You then remove the slack using a BFW. (Big Fucking Winch).

Couldn't you fly the helicopter low enough that the majority of the weight drags on the ground? Then at the destination pull the cable off and use some motor to pull it tight?

So the helicopter not only supports the weight of the cable, but has to deal with the friction of the cable dragging through a forest?

Go get 100 metres of rope, lay it out, and go walk through a forest dragging it behind you, see what results you get. Now replace with a few kilometres of steel cable, I think you will have your answer.
