LS Cable & System said on the 25th that its U.S. manufacturing subsidiary LS Greenlink has begun construction of the vertical continuous vulcanization (VCV) tower for the subsea cable factory under construction in Chesapeake, Virginia.

The LS Greenlink plant is the largest subsea cable production base in the United States and aims to be completed in the second half of 2027, with commercial production in the first quarter of 2028.

The VCV tower is a core production facility that creates the cable's insulation layer. By producing cable vertically, the VCV tower minimizes the effect of gravity, improving quality and productivity. At 201 meters tall, it is expected to be the world's largest VCV facility and the tallest structure in Virginia when completed.

The United States is pushing large-scale investment in transmission infrastructure due to the replacement of aging power grids and the spread of AI data centers. LS Cable & System said, "There is currently only one large-scale subsea cable production facility in the United States, so LS Greenlink is expected to become the largest production base in the country when completed."

Koo Bon-kyu, CEO of LS Cable & System, said, "LS Greenlink is a strategic base that can supply not only North America but also the European market," adding, "We will expand the market based on local production capacity and technological competitiveness."
