■ LS cable is among a few companies worldwide that are capable of producing the highest DC voltage cables
■ In 2023, a long-term supply contract worth KRW 2 trillion, was signed with the Transmission System Operator TenneT operating in Germany and the Netherlands


LS Cable & System announced on the 10th that it has begun mass production of 525kV High Voltage Direct Current (HVDC) cables for their first time.

It is the highest voltage product among existing DC cables. Only a few manufacturers have succeeded in commercializing these high-voltage cables worldwide. 

These cables will be used for TenneT's 2 GW grid connection systems BalWin4 & LanWin1. 

LS Cable & System signed a long-term supply contract worth KRW 2 trillion with TenneT in May last year, which was the largest single order ever obtained by any cable company in the world.

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.

LS Cable & System has recently been making efforts to take the advantageous position for the global submarine cable projects, including the construction of a plant in the US, investment in facilities for LS Marine Solutions, and promotion of LS Eco Energy's projects in Europe and Asia.
