The road in to Lake Pemaquid Camping near Damariscotta, Maine, features a curving roadway, and a primary distribution circuit that zig-zags across the road at nearly every pole. I think that this is a really good idea. It keeps the majority of the cable above the road, minimizing the amount of tree trimming needed.

Also, the hot conductor is below the static wire, which is used like a messenger to support it. Every few yards there is a spacer which serves to separate the static wire from the hot wire.

This picture shows the static wire on top, and the hot conductor below it. Note the split bolt which grounds the static wire, and the spacers which maintain the separation between the hot wire and the static wire. Looks like the bracket was repurposed from some other use.

Again, the zig-zag of this line from side to side of the road minimizes the amount of tree trimming needed to keep this line out of trouble.
