I had occassion to drive a bit round the west midlands last week, and
noticed in quite a few places, where electrickery pylons ran over a
road, then quite considerable scaffolding had been put up either side,
and a net strung over the road.

Anyone know why ? It can't be cheap, so is it a safety thing ? If so,
how come just now ?

Don't they do that when there is work being done on the cables (presumably to
stop a loose end falling onto th highway)?

no idea ... just found it strange that several (3 or 4) in such close
proximity ...

Yes, it's to stop a cable falling onto a road or building, and slicing it in
two like a cheese-wire does to cheese.

There was a petrol station that I used to pass on my way to school, back in
the days when garages didn't have all-over roofs like they do nowadays. A
pylon wire ran immediately above the pumps and there was a permanent net of
wires slung between four metal posts erected over the pumps. When my dad
once asked what it was for as he was buying petrol he was told it was to
prevent the wire falling on the pumps and to earth the 132 kV wire before it
reached the ground since any sparking could ignite the petrol.

They will probably be replacing the conductors along the whole length
(you can probably find details on the National Grid / local company website).

Yes, it is a safety thing. They will also put down access paths and erect
new fences in the fields around the pylons.
