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.
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.
@@chaz2020 It is a bit too complicated to explain in a comment section, but you can look up "Delta power connections" and "Wye power connections" and get very detailed explanations as to why there is no neutral in a delta primary (or delta secondary) connected transformer/system. But in a very loose general example, a neutral is a center tap of a single phase transformer and said neutral is usually tied to ground.
@@mxslick50 Another possible configuration in some places would be a 3 wire grounded wye system that doesn't carry out the neutral with the phase conductors. So a (possibly impedance grounded) wye source at the substation but distribution transformer primaries are connected in delta (line-line for single phase).
no, he did mention for this, they had the whole street turned off. If it WAS energized though, you’d see orange rubber placed on the lines, to protect from contact
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.

Bucket work is so fascinating. Is this in Florida? I see a lot of palm trees!

They look like a contracting firm hired by your local power company
Are they in the union?

This actually looks like a 4kv cut over not sure what the primary voltage is they’re cutting over to.

@@linehandibew6205 yeah California is usually the same.

Never seen crossarms hung that way , bucket/lift makes things easier.
4KV that's pretty low by today's standards. Nowadays they use 7.2KV to ground, 12,470 volts phase to phase.
Is that each phase or total?
@@kgeitzel3293 Phase to phase, 3 phase delta (no primary neutral). SCE has a hard-on for delta primary in a large portion of their service territory.
@@mxslick50I don’t get how there can be no neutral

Do you keep the power on when do that

Cheap wooden poles

@mxslick50 only uses steel here
