NKT delivers first order of adaptive power cable joints to Energinet

Denmark-based power cable manufacturer and installation company NKT has supplied its first order of adaptive power cable joints, which can serve as a spare joint for a broad range of HVAC offshore cables, to the Danish transmission system operator (TSO) Energinet.

According to NKT, the Adaptive Rigid Sea Joint offers reduced costs of storage as well as fewer spare parts and inventory for offshore cable owners by being compatible with various power cable types. Its versatility as a straight joint makes it fit for repairing around 350 kilometers of HVAC offshore cables in Energinet’s grid. 

Energinet is poised to benefit from this solution with a transmission grid that features numerous short HVAC power cable connections.

“We are proud to provide this new solution to Energinet, which is a long-standing partner to NKT. By delivering the Adaptive Rigid Sea Joint we are solving a challenge in the market and the contract with Energinet is a testament not only to the strong collaboration between our companies but also to their commitment to jointly optimize performance and sustainability of their activities,” said Rico Bruus, Director, Head of Service Denmark at NKT.  

NKT explains that the Adaptive Rigid Sea Joint’s levels range from 132 kV to 300 kV and accommodate over 10 power cable designs from different manufacturers. Moreover, it can be extended to encompass additional cable designs or transitions between different types.

“We are very satisfied with the ongoing cooperation with NKT. The delivery of the Adaptive Rigid Sea Joints will improve our spare parts strategy resulting in reduced costs and waste while improving the resilience of our offshore grid infrastructure,” said Rene Dogan, Offshore Cable Specialist at Energinet.

“Although we hope we will only need them sparingly, we are happy we can now rely on NKT’s experience and capabilities in the area of repair of offshore cables from different suppliers.”

Recently, NKT formed a strategic partnership with energy company Hydro to decarbonize the power cable supply chain by collaborating on low-carbon aluminum solutions for the production of medium- and high-voltage power cables.
