Prysmian Group, has successfully completed the HVDC test on the submarine interconnector COBRAcable that links The Netherlands and Denmark.

The announcement took place during the COBRAcable link’s official inauguration event, simultaneously held in Eemshaven (NL) and Endrup (DK), in the presence of representatives from the Dutch and Danish ministries, confirming the successful completion of the trial operation performed by the contractor.

Prysmian had secured this project in February 2016 with a contract awarded by TenneT TSO B.V. and Energinet SOV, operators of the Dutch and Danish power transmission grids, respectively.

Prysmian supplied and installed a ±320 kV HVDC bipole system, using single-core cables with extruded insulation technology and running for a total route of around 325 km, from Eemshaven (NL) to Endrup (DK) via the German North Sea sector. The project includes two onshore lengths of 1km on the Dutch side and 25km on the Danish side that will connect the two onshore converter stations, provided under separate contract by Siemens.
