In 2025, the global production volume of 525kV MI HVDC Subsea Cable reached 180 kilometers, with an average selling price of US$1,050 per meter, production capacity of 320 kilometers, and a gross margin of 22.0%.
525kV MI HVDC Subsea Cable refers to a high-voltage direct-current submarine power cable rated at ±525kV and insulated with mass-impregnated paper. The cable generally consists of a copper or aluminum conductor, semiconductive paper layers, mass-impregnated paper insulation, a metallic sheath, corrosion-protection layers, armoring, and an outer serving. It provides high electrical stability, resistance to hydrostatic pressure, and suitability for deep-water installation and is mainly used for cross-border or cross-sea grid interconnections, long-distance submarine power transmission, and large-scale renewable-energy export systems. Nexans has applied 525kV MI HVDC technology in major interconnector projects such as NordLink and has also completed deep-water testing of 525kV MI subsea cable systems, demonstrating the technology’s suitability for long-distance and deep-sea transmission.
The upstream industry chain primarily includes electrical copper, aluminum rod, insulating paper, impregnation compounds, lead or aluminum sheath materials, galvanized steel armor wire, optical-fiber units, polyethylene sheath materials, and accessories for high-voltage joints and terminations. It also involves specialized equipment for conductor stranding, paper lapping, vacuum impregnation, metallic-sheath extrusion, and wire armoring. Midstream participants are manufacturers with capabilities in extra-high-voltage subsea cable design, production, testing, jointing, and deep-water installation. Key processes include electrical and thermal design, continuous long-length manufacturing, factory-joint production, type testing, vessel loading, transportation, and offshore installation. Downstream customers mainly include national grid operators, transmission system operators, and major energy-project developers. Applications include international grid interconnection, island grid connection, long-distance submarine transmission, and power export from large offshore energy bases, supported by converter stations, cable-laying vessels, seabed surveys, burial and protection systems, and operational monitoring equipment.
