You could probably hang by one hand from a 20 kV power
line and be OK as long as you didn't complete a current
path to another wire or ground.

You could probably hang by both hands if they were close together. I
would not want to try it, though.

When I worked in broadcast radio years ago, I was always amazed that
service personnal would climb the 10 kw tower hot to change lights.
They stated they could feel potential between their hands as they
climbed.

But the a-c frequency is important here. The voltage gradient between
adjacent hand grips for power in a conductor at AM broadcast station
frequencies (the vertical antenna radiator, in this case) is a lot higher
for the same conducted power than for that same span along a conductor on
the 50/60 Hz a-c power grid.
