Under the €78m contract, the company will install 420kV XLPE (cross-linked polyethylene) insulated submarine cables as part of a new power link crossing two of Norway’s fjords, namely Hjeltefjorden and Lurefjorden.

Specifically, Nexans is providing a comprehensive turnkey service to BKK for the design, manufacture, supply and installation of a total of 90km of single-core XLPE cable.

Scheduled to be installed in three parallel lengths to create a three-phase AC connection, rated at 420kV, the cables will be protected by outer shells or water jetting from shore to 30m water depth.

The Lurefjorden installation will have a length of 10km per phase and a maximum water depth of 200m, while the Hjeltefjorden section will cover 20km per phase and a depth of 390m.

Nexans Submarine High Voltage vice president Kjetil Hovland said the contract reinforces the company’s position in Norway as a key supplier of cable infrastructure projects.

”It also confirms Nexans as a world leader in 420 kV XLPE submarine cables with proven capability to deliver complete turnkey systems,” Hovland added.

Manufactured at Nexans’ specialized facility in Halden, Norway, the submarine cable will be delivered and installed between 2016 to 2017.
