Hello
Question. Are there and overhead sections of DC transmission line in the UK? which would of course only have two conductors instead of the usual 3 phases? I know that there are DC interconnectors between UK-France and Scotland-N Ireland but do these have any overhead sections but are they completly underground? If there are overhead sections it would be intresting to see a pic.

We have a OH UG DC link between the north and south island of New Zealand which has 2 wires.


The product of rotation, excitation and flux produces electricty.

The Scotland-N.I. link is the quite recent Moyle Interconnector.

I seem to recall us having a discussion about it a while ago, although I don't recall whether any of it runs overhead (excepting transitions, as you would expect).

Hello.

If you use this link it will get you to the Transpower site in New Zealand.

Scroll over the little pictures below and a photo of a DC pylon with 2 wires is visible.

Kind regards Ray.

DC voltages used are 270 and 350 kV.

Next month while down South I will get some photo's of the latter.
