Submarine cables are generally available in two voltage classes, high voltage, and medium voltage.

Since higher voltages require thicker conductors, the cross section of undersea cable is larger.

Submarine medium voltage cables are similar to submarine high voltage cables and generally have the following product categories.

XLPE insulated AC medium voltage submarine cables with fiber optic cables
XLPE insulated AC medium voltage submarine cable
EPR insulated AC medium voltage submarine cable

Application：

Medium Voltage submarine cables are used for power transmission to offshore islands, oil platforms, or to cross rivers and lakes.

Cable design is based on the major national or international standards e.g. VDE, IEC, and ICEA, or according to customers' design and standards.
