The new pot they were hanging on that pole was a 4kv can. Looks like they’re keeping same voltage but just upgraded wire pots and arms. Wish they would let us take a mass outage like that in New York lol. We pull wire in hot parallel everything in and remove everything with line hot.
A lot of your old 4kv was stuff put up back in the early 40s late 30s. Even for a cut over in Baltimore you got a 90% chance your taking a decent outage. Probably why they got guys on hooks. Need every swinging dick in the yard to get it done in the time frame.
With those plastic insulators that are lightweight when compared to the old porcelain/glassware, they make easy work of lifting those new crossarms into place.
Wood poles have become almost, if not more, expensive than steel or concrete. (Due to the pressure treating and strength required.) And, in earthquake prone areas, wood poles won't crack or bend like concrete and steel can.
