XLPE Insulated AC Medium-Voltage Submarine Cable with Fibre Optic | Offshore Power & Data Transmission

Submarine Cables5
Description

Product Overview

XLPE Insulated AC Medium-voltage Submarine Cables with Integrated Fibre Optic Elements provide dual-functionality for simultaneous power transmission and data communication to offshore islands, oil platforms, and river/lake crossings. These composite cables feature robust construction with XLPE insulation, aluminium-PE laminated sheath, and galvanized steel armour, delivering reliable performance in demanding subsea environments.

Applications

  • Power and data transmission to offshore islands

  • Oil and gas platform power and communication systems

  • River and lake crossings with data connectivity

  • Submarine power distribution with monitoring capability

  • Offshore renewable energy connections with data transmission

  • Integrated power and communication infrastructure
