Trumpy,
Didn't mean to leave you hanging there. Local voltages for distribution purposes take 3 basic forms here - 4,160/2,400 Old and phasing out rapidly, 12,500/7,200 More common but still being phased out, or 34,500/19,900 which is the prevalent voltage here.

How much PVC constitutes insulation? In a bucket truck 45kv gloves on, you can grab a line and put the pocket with your keys in it near your partner and shock the living crap out of him (not that we've ever done that on purpose mind you [Linked Image] )

Also bear in mind that there is NOTHING on the market today that does not deteriorate in the sunlight. They're getting better at it, but not there yet.

That's why no PVC insulation, not effective at that voltage, nor environment.

Oh yeah, nearly forgot the extreme weight that adds to the line, BIG problem.
