SWEDEN — Cable solutions provider NKT has partnered with TenneT and TransnetBW to produce an HVDC underground power cable system for the SuedLink interconnector.
NKT has started production of the 525 kV XLPE HVDC onshore cable system with a route length of approximately 750 km (466 miles) for the German SuedLink corridor. The power cables are being produced at the NKT factory in Karlskrona, Sweden, and will be shipped to Germany for installation when completed, the manufacturer said in a press release.
The SuedLink corridor comprises two power cable systems. NKT is responsible for the 2 GW cable link which will be the world’s longest high HVDC underground power cable and run from Brunsbüttel in Schleswig-Holstein to Leingarten in Baden-Württemberg. The SuedLink line starts in Northern Germany where it connects to power from offshore wind farms and to the NordLink interconnector, which brings hydro power from Norway to Germany via a 525 kV HVDC offshore power cable system also provided by NKT.
The underground power cables are produced with a strong focus on sustainability. “Our two high-voltage production facilities in Karlskrona and Cologne operate on 100% green electricity. This way, we ensure low CO2 emissions in the manufacturing process of the power cable systems,” said Alexander Kara, CEO of NKT.
In addition to the production and delivery for the SuedLink project, NKT is also responsible for the installation of the underground power cables as well as the final high-voltage test of the cable system, NKT said in a press release.
