New 420 kV Ørskog - Sogndal power transmission link for Central Norway will feature Nexans’ conductors developed to offer a selection of colour optionsto help minimise visual impact
Paris, February 27, 2014 – Statnett, Norway’s state-owned power system operator, is deploying Nexans’ innovative coloured conductors on the new 420 kV Ørskog – Sogndal overhead transmission linkconnecting Mid-Norway to Western Norway. The new conductors will feature a special grey-green surface treatment that enables them to blend into the pine forest background on the most environmentally sensitive parts of the route.
The 297 km Ørskog – Sogndal link, planned for completion in 2016, is a strategic grid project that will provide extra transmission capacity for Mid-Norway, where there is a current energy deficit of some 7 TWh, equivalent to the annual consumption of 400,000 single-family homes. The new link will also facilitate the grid connection of around 100 small hydropower schemes.
Nexans will supply a total of 68 km of its new coloured conductors for installation on selected parts of the route where Statnett due to licensing requirements is aiming to minimise the local visual impact of the overhead lines. The patented treatment process enables any design of conductor – such as round or Aero-Z™ wires - to be produced in virtually any colour.
"Our new coloured conductors are an excellent example of Nexans’ continued commitment to developing innovative overhead line solutions that help customers build grids that minimise environmental impact", says Cyprien Federspiel, Nexans Vice President OHL Business Development. "For Statnett, the key benefit is that the coloured conductors will help the lines blend into their forest scenery. But it is also possible that some customers might want to use colour differentiation to highlight the visibility of their conductors to help make a scheme more acceptable to the local community."
