All across the globe, only LS C&S and five companies in Europe and Japan possess HVDC cable technology. The company explained that the cables are in the early stage of commercialization, so not many companies possess both the technology and construction capabilities.

LS Cable & System has signed a contract with Korea Electric Power Corporation (KEPCO) to supply KRW 108.6 billion of HVDC (high voltage direct current) cables.

This project is for the stable supply of power to industrial complexes in the metropolitan area by connecting the 35km distance from the power plant in Seohaean Chungnam to Pyeongtaek, Gyeonggi-do.

With a single HVDC line, 3GW of power can be transmitted, which is equal to the power generated from three nuclear power plants. This is the world’s largest power transmission capacity and is 4.5 times more than current HVAC (high voltage alternating current) cable.

This is the fourth project in the domestic HVDC market since European cables were first installed between Haenam and Jeju in 1997. That was before cables were developed in Korea. Since then, LS C&S has obtained the following second, third and fourth projects.

President & CEO Roe-hyun Myung of LS C&S said, “Korea is leading the global next-generation power business with HVDC and hyper-conductive cables, fueled by KEPCO’s energy efficiency business. Based on our technological independence achieved in Korea, we will actively expand our overseas markets.”
