Submarine Cables

Submarine Cables

EPR Insulated AC Medium-voltage Submarine 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.

Construction

Submarine Cables

  • Conductor Screening: Extruded semi-conductive compound.
  • Insulation: EPR.
  • Insulation Screening: Extruded semi-conductive compound.
  • Screen: Copper tapes.
  • Fillers: Polypropylene filler.
  • Separator: Binder tapes
  • Bedding Layer: Polypropylene strings.
  • Armour: Galvanized steel wires.
  • Serving: Hessian tapes, bituminous compound, polypropylene strings.
