The 525kV High Voltage Direct Current cable is the highest voltage product among the existing DC cables. These cables will be used for the 2 GW grid connection systems of TenneT, a transmission system operator from the Netherlands.

LS Cable & System has begun mass production of 525kV High Voltage Direct Current (HVDC) cables for the first time. It is the highest voltage product among the existing DC cables. Only a few manufacturers have succeeded in commercializing these high-voltage cables worldwide.

LS Cable is one of the few global companies, which are capable of producing the highest DC voltage cables. It signed a long-term supply contract worth USD 1.45 billion with TenneT, a transmission system operator operating in Germany and the Netherlands, in May 2023. This was the largest single order ever obtained by any cable company in the world.

The 525kV HVDC cables will be used for TenneT’s 2 GW grid connection systems BalWin4 & LanWin1.

The use of HVDC is increasing, especially in long-distance transmission networks, because this cable can transmit large amounts of power over long distances with lower losses compared to AC (alternating current). It is primarily used for long distance cables as to connect offshore wind and interconnectors to accelerate especially the grid expansion in Europe. The European Union has recently increased their offshore targets to 60 GW by 2030 and 300 GW by 2050.
