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.
