Case study

Near-invisible overhead lines for Statnett project

Invisible OHL for Norway
    Power networks - Land HV

Project description:

Statnett has energised a 68 km overhead transmission line connecting central Norway to western Norway, in order to reduce the energy deficit in central Norway.

Customer challenges:

  • 8.5 km of the line runs through a protected nature reserve and needed to be ‘invisible’, making it more acceptable to local residents.

Nexans solutions:

  • A unique surface treatment to manufacture the green coloured aluminum wires helps blending the conductors in with the environment. Other colours are feasible.
  • The coating has no adverse effect on the aluminum wire substrate, the conductors remain easy to connect and the colour will not deteriorate over time.
