The 5 initiatives will see NKT offering a number of 525 kV XLPE high-voltage direct present (HVDC) onshore and offshore energy cable methods. These embody onshore connections and offshore wind farm export cables SuedOstLink+ (SOL+), Ostwind 4, DC32 (NordOstLink+), LanWin 6, in addition to a hybrid interconnector for the German a part of the Bornholm Vitality Island venture.
NKT’s cable orders for the 5 initiatives cowl some 2,500 kilometres of core cables, the corporate stated.

Below its agreements with 50Hertz, Prysmian can be accountable for the design, manufacture, provide, set up, testing and commissioning of the NOR-11-1 and DC31 initiatives with an general cable size of round 1,000 kilometres.
With an influence transmission capability of two GW, NOR-11-1 is a 525 kV HVDC export cable connection that can utilise a subsea cable and an underground cable alongside the route that’s deliberate to attach the N-11-1 offshore wind farm to the German grid within the Heide/West space. The DC31 venture is a 525 kV HVDC underground cable connection and is deliberate to transmit energy from the Heide/West space to Klein Rogahn.
Prysmian has additionally been awarded as a major provider for a similar lot, which consists of a framework provision permitting 50Hertz to contract future 525 kV offshore and/or onshore initiatives with a cable core size quantity of as much as 2,700 kilometres inside an agreed interval, the corporate stated.
The subsea cables can be produced at Prysmian’s centres of excellence in Pikkala in Finland, Arco Felice in Italy, and Nordenham in Germany, whereas the underground energy cables masking each the DC31 and the underground a part of the NOR-11-1 venture can be produced in France.
Prysmian additionally says it would leverage its fleet of state-of-the-art cable-laying vessels to carry out marine set up operations, together with the laying and burial of offshore cables.
