In the past year and a half, the 22.9kV superconducting cable of LS cable in South Korea has been successfully applied to the actual line system in the suburbs of Seoul, South Korea, achieving accident free operation and obtaining the "Practical Line Application Qualification Certification" granted by South Korean Electric Power Company. At the same time, the relevant equipment and operation work have been successfully transferred to South Korean Electric Power Company. Through this, LS Cable has become the only enterprise in the world that integrates the development of superconducting cables, intermediate junction boxes, terminal junction boxes, and cooling/control systems for the entire superconducting cable system, while also successfully completing installation and operation.

In mid August 2011, LS cable successfully laid a total length of 410 meters of 22.9kV superconducting cable for the Lichuan substation. As the world's longest distribution superconducting cable, it provided power to nearly 1/5 households in Lichuan and surrounding factories and farms.

Superconducting cables use superconductors with a resistivity of "zero", which have no power loss and can transmit more than 5 times the electricity of general cables. They can be more effectively applied to underground cable trenches in gradually saturated urban centers, without the need to build substations for long-distance power transmission. In the long run, superconducting cables can also be referred to as the "dream technology" by the industry as the basic technology for smart grid power transmission between countries and continents.

LS Cable CEO Ju Ziyin said, "LS Cable has always been committed to the development of advanced technologies such as superconducting cables and submarine cables, especially superconducting cables that are preparing for practical line application certification." In March 2013, LS Cable will complete type testing of 154MVA grade products with three times higher transmission capacity than the 22.9kV 50MVA grade products handed over to Korea Electric Power Company.
