LS Cable & System Expands with Major HVDC Cable Facility
LS Cable & System (LS C&S) completed Asia’s largest high-voltage direct current (HVDC) underwater cable production plant in Donghae, Gangwon Province, South Korea. The new facility, called Submarine Building 4, marks a major milestone for the company’s growing submarine cable business.
Inside the New HVDC Plant
The new Donghae plant features a 172-meter-tall vertical continuous vulcanization (VCV) tower covering 34,816 square meters of floor space. LS C&S invested approximately $141 million in the project, which began construction in July 2021. With this new facility, the company significantly boosts its capacity to produce advanced underwater power cables for global energy projects.
Accelerating Growth in the Energy Transition Era
Since opening South Korea’s first submarine cable plant in 2008, LS C&S has made consistent investments to expand its marine and offshore power cable capabilities. Recently, the company strengthened its market position by acquiring a 43.8% stake in KT Submarine, becoming its largest shareholder. This move enhances LS C&S’s presence in both domestic and international cable markets.
LS C&S CEO Koo Bon-gyu emphasized that the new HVDC plant will accelerate the company’s growth amid the global energy transition. “We will contribute to the advancement of the electric power industry through efficient energy networks and improved national competitiveness,” he said.
Expanding International Reach
In December, LS C&S secured a landmark contract to supply HVDC cables for the Vanguard Wind Power Complex in the United Kingdom, marking Korea’s largest cable deal in Europe to date. This achievement highlights the company’s growing influence in global renewable energy projects.
At the completion ceremony, more than 100 distinguished guests attended, including LS Group Chairman Koo Ja-eun, LS Corp. CEO Myung Roe-hyun, and LS C&S CEO Koo Bon-kyu. Their presence underscored the project’s strategic importance for both LS Group and Korea’s energy sector.
