The very high voltage lines in the electricity transport network
19 February 2008
- A 400,000 volt line
These are the arteries of the transport network.
They are of impressive size. Very high voltage lines are designed to transport large amounts of power safely and to stand up to severe weather. New safety measures have been introduced for these lines since the storms of 1999.
The most visible part of these networks are the cables and supports (pylones and poles). The pylons can be as much as 45m high and 57m wide and each carries one or two circuits consisting of three power cable assemblies and one or two ground wires to protect against lightning.
Special studies are performed so these lines fit into the landscape as well as possible.
