If it helps, the typical utility pole for 12.47/7.2KV Wye primary service (which is what this appears to be) is 45 feet with about 6 feet of that buried in the ground. This would make the primary conductors about 40 feet AGL.
Thanks for that.
That is higher than my rough estimate based on the height of the engineers in the pic I posted, and the height of a semi trailer passing a pole on a Google streetview pic on a road nearby.
I made the poles about 25 feet tall with the cables at about 20 feet.
