132kV Submarine Cable – Cable Manufacturer

А 132kV submarine cable is a high-voltage power transmission cable designed for underwater installation. It is widely used in offshore wind farms, island power supply systems, and cross-sea electrical grid connections. These cables must operate reliably in extreme marine environments where they face challenges such as high water pressure, saltwater corrosion, seabed movement, and mechanical damage from anchors or fishing equipment.

Modern submarine cables typically use XLPE insulation technology, copper or aluminum conductors, metallic water barriers, and strong steel wire armoring. These features ensure high electrical reliability and long service life, usually exceeding 30-40 жил.
