I’ve never seen suspension insulators up close before so was a bit confused as to why there’s so much metal in-between the glass (porcelain, ceramic?) discs? Obviously for strength since the high tension wires are heavy and create a lot of stress. Nevertheless, how do these things insulate so well – especially in wet weather?? I’ll research the matter further and try to post an answer here.
This particular video recording in near the Valmont power generating facility in Boulder, Colorado. I believe the lines, in question, supply 230,000 volts but I’ll have to double-check that as well. The insulators were lying on the ground immediately adjacent the Boulder Creek bike path.
