SEOUL – LS Cable & Systems, a leading cable manufacturer in South Korea, has developed a new superconducting coaxial cable which can transmit large amounts of energy, little loss of power during power transmission and generates no electromagnetic wave.

LS C&S worked with KEPRI, a research unit of the South Korean state-owned company Korea Electric Power Corp. (KEPCO), to develop a 23 kilovolt (kV) class superconducting coaxial cable that significantly increased power transmission. Of the three companies that have successfully developed next-generation superconducting cables, LS C&S said its product was the first to receive certification from the International Electrotechnical Commission (IEC).

LS C&S said the new product can improve the structure of superconducting layers to increase power transmission by more than 20% compared to existing products while reducing production costs by more than 10%. The company said its new cable can be applied to KEPCO’s superconducting platform business which will begin in 2022.

The business of superconducting platforms can reduce the size of substations to less than a tenth of existing ones and reduce construction costs by more than 30%, the cable operator said, adding that it would increase its use in city centers where it is difficult to expand electrical installations. .

With its new product, LS C&S aims to expand superconducting cables into domestic and foreign markets. “With the global trend of ESG management, the superconductor industry is expected to expand in North America and Europe. We will make efforts to enter the global market based on our marketing experience in our country,” said CEO Myung Roe-hyun said in a statement on Oct. 13.

LS C&S has participated in many projects abroad. In November 2020, the company entered into a five-year contract for the supply of high voltage cables for offshore wind farms to Orsted, a Danish electricity company. In early October 2021, LS C&S reached an agreement for the supply of submarine cables for an offshore wind farm in Taiwan by 2025.
