voltage is now carried on single wooden poles.

Thanks. Do you know how much current is carried on these high-voltage
wires?

Other installations such as this one

are to link wind farms etc into the network.

Thanks, I did see some of the wooden twin-pole units around there too.
I presume they use them at places where the direction of the lines
changes, and (in this case) where it meets the M6 and presumably needs
a bit more hight to clear the carriageways.

11000 Volt. * Rough guide used to be 2 wires 11000 Volt, 3 wires 33000
Volt but as your first query shows *its not that straight forward
anymore.

Pardon my ignorance, but wouldn't a 3-phase supply need 4 wires - the
3 phases plus a neutral? Or does it not work like that?
