APPLICATION

The core of the submarine power cable is covered with a PE outer sheath. After the single steel armor, the cable is finally completed with an outer sheath. So it is mainly for all marine environmental conditions, such as muddy, dry, wet, or oily conditions meeting the requirements. The range of voltage is 6/10(12)kV,12/20(24)kV, 18/30(36)kV, and so on.

XLPE Insulated DC High-Voltage Submarine Cable

A high-voltage submarine cable is used for high-voltage power transmission. Most of the submarine power cables are on the seabed at a certain depth, and they are not damaging the natural environment, such as wind and waves. Human production activities have interfered with them. Therefore, the cables are safe and stable, with strong anti-interference ability and good confidentiality.

  • Conductor: Copper conductor, water blocked
  • Conductor Screening: Extruded semi-conductive compound
  • Insulation: XLPE
  • Insulation Screening: Extruded semi-conductive compound.
  • Separator: Swelling tape
  • Core Sheath1: Lead Sheath
  • Core Sheath2: PE sheath
  • Bedding: Bedding layer
  • Armour: Galvanized steel wires filled with bitumen compound
  • Serving: Polypropylene yarn

STANDARDS&REFERENCES:IEC 60228, IEC 60502, IEC 60840, IEC 62067

APPLICATION

As a high-voltage power transmission cable, it is major for carrying electric power below the surface of the water. The range of voltage is 127/220(245)kV, 160/275(300)kV, 200/345(362)kV, 230/400(420)kV, and so on.

ZMS Submarine Cable Service

Submarine cables have always been developed with the rapid development of global technologization, nowadays, all countries are competing to be the first to develop submarine cable manufacturing and laying technology so that the earth is clothed in submarine cables map network.ZMS Cable is a global cable manufacturer with a certain scale of submarine cables market in the world. Such as aerial cables, control cables, and armored cables.

When choosing ZMS Cable, we will attach according to the submarine cable specifications provided by the customer and provide a submarine cable laying program.ZMS understands that submarine cable laying consists of three main phases: cable routing surveys and cleanups, submarine cable laying, and burial protection. When laying submarine cables, it is necessary to control the angle of water ingress and increase the tension of laying submarine cables by controlling the sailing speed. All these are the rich experiences ZMS has.

As a professional submarine cable company, we offer high-quality cables in various constructions and voltage ratings. In addition, we also support customized products according to your requirements. We provide you with high-quality and low-price materials. Please feel free to contact us.
