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
应用
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)电压,12/20(24)电压, 18/30(36)电压, 等等.
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. 所以, the cables are safe and stable, with strong anti-interference ability and good confidentiality.
