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

• 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.
