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

[ China Instrument Network Instrument Development ] Recently, LS Cable, a leading South Korean cable manufacturer, unveiled the world's thinnest 500 kV transmission cable and several other innovative products at CIGRE in Paris, France. This breakthrough marks a significant step forward in power transmission technology and highlights the company’s commitment to innovation.

Founded in 1962, LS Cable has grown into a global leader in the cable industry, providing high-quality cables and comprehensive solutions for both daily use and industrial applications. The company plays a vital role in building power grids and communication networks across Korea and around the world. With a strong focus on technological innovation, LS Cable delivers specialized cables and materials that support various industries, contributing significantly to global economic growth.

Today, LS Cable supplies 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 pioneer in the field of industrial infrastructure, the company continues to shape the future of energy and communication systems.

Transmission cables are essential for delivering electricity from power generation sites to end users. The increasing demand for renewable energy, reliable power supply, and modernized grid infrastructure has driven growth in the transmission cable market. Additionally, rapid urbanization and industrial expansion have further fueled this development. Among these, the 500 kV cable stands out as the highest voltage underground cable currently available in 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. This reduction in diameter while maintaining or even improving transmission capacity reflects a key trend in the cable industry. Moreover, LS Cable has developed various submarine cable technologies, including long-distance transmission lines that span hundreds of kilometers underwater and specialized solutions for offshore wind farms.

Notably, LS Cable’s high-voltage direct current (HVDC) power 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 systems of Korea, Japan, Russia, and China, this technology has attracted considerable attention.
