Event Summary

Danish cable manufacturer NKT has qualified a 525 kV HVDC extruded XLPE subsea power cable system for continuous operation at conductor temperatures up to 90 degrees Celsius. This qualification, announced on August 24, 2026, enables increased transmission capacity, reduced material consumption, or improved system efficiency depending on project requirements. The upgrade is based on a redesigned insulation system using a new semiconductive material, LE0650DC, developed jointly with Borouge (formerly Borealis (company)). The technology is qualified for both onshore and offshore applications up to 525 kV, including accessories. This advancement strengthens NKT's HVDC portfolio for offshore wind, hybrid interconnectors, and future cross-continent transmission lines. NKT has recently secured major 525 kV HVDC contracts, including around EUR 2 billion with SSE plc — SSEN Transmission for links in United Kingdom — Scotland and over EUR 2.2 billion for the Eastern Green Link 3 between United Kingdom — Scotland and Bret Engemann, though it has not indicated the new 90C configuration will be used on these projects.
