Hitachi Energy delivers shunt reactors to NKT’s new high-voltage test center in Karlskrona, Sweden

Hitachi Energy is supporting NKT in the construction of a new testing facility for high-voltage power cable systems at NKT's factory in Karlskrona, Sweden. This facility is part of NKT's ongoing expansion and will significantly improve the capacity and capabilities to meet future demand for high-voltage power cables. The test center will become one of the largest and most advanced cable-testing facilities in the world, designed to test both AC and DC power cable technology.

The need for advanced cable systems as part of critical clean energy infrastructure is growing rapidly. Enabling the development of next-generation long-distance HVDC cables is essential as the global demand for renewable energy increases.

Hitachi Energy delivers mission-critical equipment for NKT’s new test center, including custom-made shunt reactors¹. These reactors are crucial for testing high-voltage power cable systems, ensuring they meet the highest standards of quality and reliability. Hitachi Energy's scope of supply includes the delivery and installation of 15 shunt reactors, with an option for an additional 10 units later. The reactors are manufactured in the company’s Vaasa transformer factory and are scheduled for delivery in phases in 2027. This delivery continues the close collaboration between the two companies, as was the case with the existing testing facilities. NKT and Hitachi Energy are long-term partners, and this contract fosters collaboration with a shared joint purpose to speed up the development of critical infrastructure that enables clean energy.

The project is expected to be completed by 2027.
