LS Cable & System inked a 200 billion won deal that would connect South Jeolla Province’s Wando to Jeju Island with 90 kilometers of high voltage, direct current (HVDC) submarine cable.
The project is slated for completion by the end of 2023.
LS C&S, the world’s third-largest wire and cable maker by sales, will be undertaking the entire process from design to its completion, in a turnkey format.
It will transmit Jeju-generated renewable energy to the mainland while providing stable electricity to meet Jeju’s increased power demand.
LS C&S is the only Korean company among the five global cable providers capable of building such extensive turnkey projects dealing with submarine cables.
In 2013, LS C&S carried out a similar project when it built a 105-kilometer submarine cable running from Jindo to Jeju Island.
Short of electromagnetic wave emissions, HVDC cables are considered environmentally friendlier than armor-clad cables.
To address the growing global demand for eco-friendly energy, LS C&S is seeking to build an HVDC production facility in Donghae, Gangwon Province next year and steadily expand related investments.
