LS Cable & System announced on the 9th that it has successfully commercialized the world's largest transmission capacity of high-voltage direct current (HVDC) cables and will supply it exclusively for the first phase of the Korea Electric Power Corporation "East Coast- metropolitan area" transmission network.
This product is a high-temperature HVDC cable rated at 525 kV, with the conductor's allowable temperature increased from the previous 70℃ to 90℃, enhancing transmission capacity by up to 50%. It is expected to be deployed in the underground section of the "East Coast-metropolitan area" HVDC first phase in September.
The "East Coast-metropolitan area" transmission network project is a national key power grid initiative aimed at efficiently transporting power generated in the East Coast region to the metropolitan area. The first phase covers the section from East Coast to the Singapyeong converter station, while the second phase connecting to the metropolitan area is also in progress.
HVDC has lower transmission losses than conventional alternating current (HVAC) and can deliver up to three times more power over long distances. Currently, only six corporations worldwide have commercialized this technology, and LS Cable & System is the only one in Korea.
Lee In-ho, head of technology development at LS Cable & System, noted, "The competitiveness of the HVDC market depends on securing commercialization technology. We plan to actively participate in major domestic and international projects, including the 'West Coast HVDC energy highway', 'East Coast-metropolitan area' second phase, and the second phase of the German Tennet project."
