LS cable develops the world's thinnest 500 kV transmission cable

China Instrument Network Instrument Development Recently, South Korean cable manufacturer LS Cable unveiled the world's thinnest 500 kV transmission cable and other innovative products at CIGRE in Paris, France. This breakthrough marks a significant advancement in power transmission technology.

Founded in 1962, LS Cable has built a long-standing reputation as a leader in the cable industry. The company specializes in developing, manufacturing, and supplying cables and related solutions for both daily use and industrial applications. It plays a crucial role in supporting the development of power grids and communication networks across Korea and globally. Through continuous innovation, LS Cable provides specialized cables and industrial materials that support various sectors and contribute to economic growth.

Today, LS Cable offers advanced products such as submarine cables, superconducting cables, ultra-high voltage cables, and communication cables to major power companies, heavy-duty motor manufacturers, and telecom firms in North and South America, Europe, the Middle East, and Asia. As a global leader in industrial infrastructure, the company continues to shape the future of energy transmission.

Transmission cables are essential for delivering electricity from power generation sources to end users. With the increasing demand for renewable energy, reliable power supply, and modernized grid systems, the transmission cable market is growing rapidly. Urbanization and industrial expansion further drive this trend. Among these, the 500 kV cable stands out as the highest voltage underground cable currently available on the market.

Compared to traditional options, LS Cable’s 500 kV cable is more than 5% thinner, making it easier to produce, transport, and install. Thinner cables with higher transmission capacity represent a key technical goal in the industry. Additionally, LS Cable has introduced advanced submarine cable technologies, including long-distance underwater transmission lines and specialized solutions for offshore wind farms.

Notably, LS Cable’s high-voltage direct current (HVDC) transmission system enables efficient power transfer from low-cost to high-cost regions. As a core component of the Northeast Asian supergrid connecting the power networks of Korea, Japan, Russia, and China, this technology has attracted widespread attention.
