I have come up with what I think will pass for N scale power lines. I took some plastic telephone poles and cut off the bits I didn't want. Added some tiny glass beads for the insulators and have found something I think will pass for wire. The tiny glass beads are for making jewelry and come sold in 3 oz. packages. More than I will ever need. The wire will be made with something called "Beadalon" made for stringing beads together. It comes in 60 foot rolls, is .015 inch and is very strong and smooth. I have not started stinging the wires yet and was just wondering if this will pass for wire and insulators.
