Nexans’ XLPE Cables to Increase Security of Power Supply in Denmark

Nexans will manufacture and supply XLPE submarine and underground cables to connect Danish substations

Denmark’s electricity grid is to be reinforced with more than 290 km of Nexans’ XLPE cables as part of ENERGINET.DK’s JFK & Storstrømmen project. Nexans will supply two submarine cable systems and two underground cable systems in Denmark in a contract worth approximately €25 million.

Nexans will provide a 150 kV single core cross-linked polyethylene (XLPE) underground
3-phase cable system to connect the substations from Ryttergård over Graderup to Fynsværket. The second cable system will connect the Abildskov substation to the Sønderborg substation. In addition to the two underground cable systems, Nexans will also deliver accompanying accessories and carry out the cable laying supervision and installation.

Nexans’ 3-core 150 kV XLPE submarine cables will run from Jutland in central Denmark to the island of Funen in the east and on to the island of Als in the south. Further a 132 kV submarine cable will connect the substation at Rosenfeldt on the island of Zeeland to the Orehoved substation on Falster island. The cables will be used to increase the security of supply in the region.

The JFK & Storstrømmen project is part of a Danish national initiative to move the majority of power cables underground by 2030. The Cable Action Plan will see 2,900 km of new power lines installed as underground cables and replacement of 3,200 km of existing 132 kV and 150 kV overhead lines.

Nexans and ENERGINET.DK previously collaborated on the Køge Bugt project, also part of the Cable Action Plan, and will start working to connect Kriegers Flak offshore wind farm to the Danish Grid thereafter.

The cables will be manufactured at Nexans’ plants in Hanover, Germany and Halden, Norway. Delivery will start in March 2016.
