Actually the the very high lines on the top of the poles are all bares they are all hots......(some of them have weatherproof coating but does not work as a insulators though....) Creepy in some ways huh?
Funny thing is that that copper oxide and copper chloride coating can act as a very good insulator, allowing the lines to twist and touch without tripping.
there is one support near me where the Golf area is at the intersection of Route 29 and Old Columbia road that completely snapped and broke....but the pole has been standing the whole time...and there is a VERY old LARGE black transformer up there...I do not know the best way to report it though.......
