Posting some typical north American power infrastructure in response to a discussion earlier today.
This pole is in a downtown area and is mixed transmission, distribution, and communications.
Top lines with largest spacing are transmission, feeding to a substation the next block over. Probably 100+ kV.
The ones on the cross arm are distribution, probably around 10 kV. Both 3 sets are 3 phase.

A few poles down the street the transmission has gone in a different direction and we see typical major street pole layout. This pole has three primary phases at teh top on trh cross arm, with the leftmost phase connected to a single phase side line driving a pole transformer across the street. The three transformers on this pole probably drive three phase loads in the auto repair business I'm in front of. Further down we see a spaghetti of telecom lines.

@azonenberg@ioc.exchange and that is why they teach you to hop away on one foot in case you hit a pole
