LS Cable & System and LS Marine Solution are showcasing technologies spanning next-generation power grids and resource recycling at a climate industry exhibition in Busan, as the expansion of renewable energy increases demand for more efficient and sustainable transmission infrastructure.
The two companies are participating in the Carbon Neutrality Expo at the 2026 World Climate Industry Expo, being held at BEXCO in Busan from Sept. 16 to 18.
At the center of their exhibition is what the companies describe as a “one-stop integrated power grid,” connecting renewable energy generation sites with end users. The display includes submarine cables used to transmit electricity from offshore wind farms to land and superconducting cables designed to carry large amounts of power efficiently.
LS Cable & System is presenting its commercialized 500kV high-voltage direct current, or HVDC, cable technology, while LS Marine Solution is highlighting its experience in installing HVDC submarine cables.
The technologies are becoming increasingly relevant as renewable energy projects expand farther from major consumption centers. Offshore wind in particular requires high-capacity transmission infrastructure capable of moving electricity over long distances while maintaining grid stability.
Focus Expands From Power Transmission to Materials and Recycling
The exhibition also reflects a broader shift in the cable industry toward reducing environmental impact throughout a product’s life cycle, from materials and manufacturing to disposal and recycling.
LS Cable & System is displaying cables made with recyclable polypropylene, or PP, insulation. The material is designed to offer a more recyclable alternative to conventional cable insulation materials.
Another technology on display is Cuflake®, a copper material developed for use in copper foil production. The company uses copper scrap as a raw material, reducing processing steps and energy consumption compared with conventional production methods.
The companies are also presenting technology for recycling cross-linked polyethylene, or XLPE, commonly used as cable insulation. Recycling XLPE has traditionally been difficult because of the material’s cross-linked molecular structure.
To demonstrate how recovered materials can be returned to the production cycle, LS Cable & System is displaying craft products made from recycled copper in collaboration with traditional metal artisans in Anseong, south of Seoul.
The approach illustrates how cable makers are moving beyond supplying infrastructure for the energy transition to addressing the environmental footprint of the cables themselves.
ESG Programs Added to Technology Exhibition
Visitors can also participate in programs focused on environmental, social and governance initiatives. One activity allows participants to make keychains using discarded plastic.
The exhibition also features a performance by the BeSol Art Troupe, a vocational arts group for people with disabilities operated by LS Cable & System.
“Energy transition requires not only the expansion of power grids but also environmental considerations throughout the entire process of production, use and recycling,” an LS Cable & System official said. “We will continue strengthening our green power grid technologies and resource recycling capabilities to contribute to building sustainable power infrastructure.”
