Submarine Cables

XLPE Insulated AC Medium-voltage Submarine Cable With Fibre Optic Cable

Applications

These submarine cables are used for power transmission to offshore islands, oil platforms or to cross-rivers and lakes. Cable design based on the mayor national or international standards e.g. VDE, IEC and ICEA or according to customers design and standards.
