General – Cable Repair
NKT has finalized the repair of the 285 kV HVDC power cable system Kontiskan 2, connecting the power grids of Sweden and Denmark.
The repair operation was completed in only 12 days due to close collaboration of all parties involved and NKT’s extensive experience in offshore repairs.
NKT was awarded the repair contract after the Kontiskan 2 interconnector – operated by Svenska Kraftnät and Energinet, Denmark, – suffered a fault due to external impact at the end of January 2022.
Roughly eight weeks after the fault occured, the 285 kV mass impregnated (MI) HVDC power cable system was back in full operation, while the actual repair operation took only 12 days.
