NKT starts construction of new cable extrusion tower for the world’s largest high-voltage offshore cable factory

A constant flow of trucks is now delivering concrete to the construction site in Karlskrona, Sweden, where NKT is building the world’s largest high-voltage offshore power cable factory. NKT has now started the slipforming casting of concrete for a third extrusion tower at the Swedish factory.

Over the coming months, a truck per hour will supply concrete to the tower, ensuring its rapid ascent to 200 meters to stand as a landmark of NKT’s ongoing investments in production capacity and capabilities. The expansion with the new tower is driven by a record high order backlog and increased demand for power cables supporting the transition to renewable energy.

- The beginning of the slipforming is a major milestone in the expansion of the factory in Karlskrona. The tower will significantly strengthen our ability to meet the growing demand for larger and longer high-voltage offshore cables essential for the green transition. The ongoing investments is central to the execution of our large order backlog and prepares us for the positive development, we expect in the high-voltage power cable market. With the capacity expansion, we continue to be a leading power cable provider for the global energy infrastructure, says Darren Fennell, Executive Vice President and Head of HV Solutions Karlskrona in NKT.

The extrusion tower is crucial in adding insulation to the high-voltage power cables produced at theSwedish facility. The construction of the tower is part of a larger investment program in NKT’s high-voltage power cable business, which also includes a second cable-laying vessel set to be operational from 2027 alongside the factory expansion. As part of this growth, NKT plans to recruit over 500 new employees by 2027 and is on track with the hiring process in Karlskrona.
