Now there are issues about this one. It seems that in the windiest places
the fix is to have the pylons closer together. This is done in some
countries, but it seems that in the same way we suffer from no snow
ploughs or whatever we refuse to do the correct engineering thing.#


We do not get ice storms and wind often enough to make it cost effective.
Of course underground also has its problems due to ground movement and the
need for extremely good insulation and thicker conductors as they will
get hotter.


I just think we have a history of not wanting to do things in an over
engineered fashion, but as the climate extremes get worse,


You donít know that.

somebody is, eventually going to have to bite the bullet on all these
things.


Or that either.

Has anyone heard of how many wind turbines were damaged by the storms of
the last few days. We know of course that they cannot be used in high
winds or for very gusty winds with variable direction.

cost of repairing overhead 11KV fault. £2000.

Cost of undergrounding it - £30,000 per kilometer.

Dave, lefty**** that he is, still thinks there is a magic money tree
somewhere that 'capitalists' have 'kept all to themselves'...

Bless.
