EPR Insulated AC Medium-voltage Submarine Cable | Offshore Power Transmission Cable

Product Overview

EPR Insulated AC Medium-voltage Submarine Cables are designed for reliable power transmission to offshore islands, oil platforms, and river/lake crossings. Featuring ethylene propylene rubber (EPR) insulation and robust galvanized steel wire armour, these cables deliver exceptional performance in demanding subaqueous environments while complying with major international standards including VDE, IEC, and ICEA.


Applications

  • Power transmission to offshore islands

  • Oil and gas platform power supply

  • River and lake crossings

  • Submarine power distribution networks
