Electric power, I believe, is distributed to residential areas
as 2200 Volt lines. Before entering the home, this voltage is
stepped down to 220 Volts with a pole-mounted transformer.

Generally the primary side of a residential transformer is
at from 12kv to 25kv. I wouldn't advocate going anywhere
near a 12kv conductor.

Note that many arial primaries are uninsulated. Another reason
to avoid them.
