Over the past year and a half, South Korea, LS Cable 22.9kV level superconducting cables in the outskirts of Seoul, Korea successfully applied to the actual line system to achieve accident-free operation, won the Korea Electric Power Corporation awarded the "actual line application qualified certification", while the relevant equipment and operation work successfully handed over to the Korea Electric power Corporation. Whereby, LS cable as the only global development of a set of superconducting cable, indirectly box, terminal block and a cooling / control systems for the integration of the entire superconducting cable system, while the successful completion of the installation, run the business.

In mid-August 2011, LS Cable for the Icheon substation successfully laid a total length of 410 meters 22.9kV class superconducting cable, as the world's longest superconducting cable distribution, nearly one-fifth of Icheon family and the surrounding factories farm implements regional power.

Superconducting cable using resistivity was "zero" superconductors, no power loss, the transmission cable generally charge more than 5 times, can be more effectively applied to the gradual saturation of the city center underground cable channel, while eliminating the need to build long-distance power transmission substation reality . In the long term, the superconducting cable can also be realized as a national, inter-continental smart grid technology based power transmission industry as "the dream of technology."

LS Cable CEO Koo Cha Yin expressed: "LS Cable has been developing superconducting cable and submarine cables and other advanced technologies, in particular superconducting cables are preparing for the actual line application authentication." March 2013, LS Cable the transfer will be completed than to Korea Electric power Corporation's 22.9kV 50MVA class products three times higher feed-in power type tests 154MVA class products.
