That's what I was thinking. A main 275kV pylon is around 50m high, and
visible for miles around. It won't cause a problem on a map because
there is no way anything can be under it. You can see them clearly in
the Yahoo Imagery. This is the only kind of power line I have been
adding. E.g:
http://www.openstreetmap.org/?lat=51.75279&lon=-1.31145&zoom=16&layers=B0FT

A local power line connecting a couple of farmhouses at 240V or 415V is
similar to a telegraph pole, and will typically be next to a farm track
or something. It is likely that as it runs along one side of the track,
it will be draw a line through the track at certain zoom levels.
