very small. what wattage?

Nice find, they don't look much bigger than those halogen floods from the box store.

Thanks, I think they are somewhere between 100 and 175, but they might be 250. @Joseph, yeah they aren't much bigger!

I wonder what the voltage of the powerlines on top are. xD

I'm not sure, I'd guess around 14 kV.

Those are big insulators. I'd guess 24KV or 30KV

It's hard to say, these lines actually go directly into the side of a building!

did you get a pic of that?

My insulators I own (that are about that big) held power lines that were 45 KV. Just that small section of the 45 KV lines were taken down and most of the string is still up. (The 45 KV power lines are in walking distance from my house)

I guess these might be in that range. Not sure. Probably less or more though.

And were there insulators on the side of the building?

Nope, these later connect to regular distribution lines with 14 kV sized insulators, it is likely they use to be higher though. And yes there where insulators on the building, you'd be pretty hard pressed to get away without insulators.

Do you have any street views of these power lines? Like when they connect to regular lines and when they connect to the building.

See here.

What about when they connect to the building?

There is no street view at the building, but they connects to that building way off in the distance.

I do notice on the street view that the first pole the big insulators don't have wires on them. But the ones under it go on the top ones. So I guess those are older power lines that were changed out. and voltage lowered.
