Korea’s KEPCO commercialises superconducting power transmission technology

The Korea Electric Power Corporation (KEPCO) has successfully commercialised superconducting power transmission technology for the first time in the world. It has built a 23 kV, 50 MVA power transfer system between the Shingal and Heungdeok substations, in which a 1 km section has been equipped with this technology. The superconducting cables have been laid by Korea-based industrial corporation LS Cable & System. KEPCO plans to commercialise a 154 kV superconducting power transmission system and build a superconducting platform by deploying three-phase superconducting cables of 23 kV.
