LS Cable has successfully commercialized a high-voltage direct current (HVDC) submarine cable with the highest transmission capacity.
On July 9, LS Cable announced that it has passed the international certification process known as Pre-Qualification (PQ) for its 525kV·80℃ HVDC submarine cable, becoming the first in South Korea to do so. This certification establishes a supply foundation for products that can be immediately applied to the West Coast Energy Highway project.
In future contracts, the company will only need to undergo a simplified type test before supplying products.
The newly developed submarine cable has increased the allowable temperature of the conductor from 70 degrees to 80 degrees, significantly boosting transmission capacity by up to 25%. It is recognized as a next-generation power grid technology optimized for long-distance and large-capacity transmission, requiring advanced high-voltage insulation technology and long-term reliability.
LS Cable's major subsidiaries are also accelerating their competitiveness in line with the expansion of the power infrastructure market. LS Eco Energy has completed PQ testing for a 400kV high-voltage cable aimed at the North American market, while Gaon Cable has finished developing high-voltage cables that meet Korea Electric Power Corporation standards and plans to begin full-scale supply next year.
An LS Cable official stated, "Passing this PQ test is a significant milestone for securing a foothold in the next-generation national power grid market," adding, "We will solidify our strategy to target both the domestic energy highway and the global HVDC market by combining our manufacturing and construction turnkey capabilities with LS Marine Solutions."
