Using Feature:

1. The long-time working temperature of the cable should not be higher than 70℃.
2. When the core is in short-circuit (max 5s) the temperature should not exceed 160℃.
a. For a single no-armored cable, it is not less than 20 times of outer diameter
b. For single-core armored cable, it is not less than 15 times of outer diameter
c. For multicore no-armored cable, it is not less than 15 times of outer diameter
d. For multicore armored cable, it is not less than 12 times of outer diameter

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, a laila.

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. No laila, 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
ʻO ka hoʻokaʻawale: 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, a laila.

Standards and Applications

STANDARDS: IEC 60502, IEC 62067

APPLICATIONS: This applies to a solidly earthed system with a power frequency of 50-60Hz and rated voltage from 1kV to 500kV. Mainly used for high-power electric power transmission between mainland and island, island and island, or mainland and platform; control signal transmission of smart grid and communication signal transmission.
