The COBRA cable is being developed by Dutch transmission system operator TenneT and its Danish counterpart Energinet and is intended to increase the security of supply of both countries.
Prysmian will supply and install a HVDC bipole using single core cables with extruded insulation technology that will operate at a voltage level of ±320 kV with a rating of approximately 700 MW.
It will run along a 325-kilometre route from Eemshaven in The Netherlands to Endrup in Denmark via the German sector of the North Sea.
It will include two onshore lengths of 1 km on the Dutch side and 25 km on the Danish side to link to the onshore converter stations, which are to be provided under a separate contract by Siemens.
All Prysmian’s cables will be manufactured at its facilities in Naples, Italy and Helsinki, Finland and delivery of the cable system is scheduled for the third quarter of 2018.
