LS Cable & Systemย has successfully completed a high-voltage direct current (HVDC) submarine cable project connecting Wando and Jeju Island, South Korea. The $160 millionย Wando-Jeju HVDC projectย covers approximately 90 kilometers under the sea, linkingย Wando, Jeollanam-do, toย Jeju Islandโsย power grid. This milestone marks the companyโs largest submarine cable project since the Jeju 2-linked contract in 2009.
This project represents South Koreaโs first use ofย voltage-type HVDC technology, a groundbreaking system that enablesย real-time controlย of electricity flow andย fast restorationย of power during failures. The new submarine cables enhance the stability of Jejuโs energy supply by increasing the amount of electricity transmitted between the island and the mainland.
LS Cable & Systemย emphasized that only a few companies in Europe and Japan have commercialized HVDC submarine cable systems, while LS Cable remains theย sole provider in South Korea. The project showcases the strength of national collaboration, with domestic partners such asย LS Marine Solution, major construction firms, andย KEPCOย (Korea Electric Power Corporation).
Kim Hyung-won, head of LS Cable & Systemโs Energy and Construction Division, highlighted the project as a โTeam Koreaโ success, achieved through seamless cooperation between leading Korean companies. This accomplishment reinforces South Koreaโs position as a leader in next-generation power transmission and undersea cable innovation.
