Product Details

300mm2 XLPE insulated and PVC sheathed power cable

Introduction of XLPE cable:

1. Use of high voltage cable

High-voltage cables are suitable for the fixed laying of power transmission and distribution lines with AC 50HZ and rated voltage 66KV and below for power transmission.

2. Use function

The maximum rated temperature of the cable conductor is 90 ℃

During the short-circuit period (the longest duration does not exceed 5s), the maximum temperature of the cable conductor shall not exceed 250 ℃

The ambient temperature when laying cables shall not be lower than 0 ℃

Features and uses of XLPE insulated power cables:

The cross-linked polyethylene insulated power cable has the characteristics of high mechanical strength, strong environmental stress resistance, excellent electrical performance, and strong current resistance.

Chemical attack. In addition, the lightweight and simple product is easy to use. This product is suitable for transmission and distribution systems with a rated voltage of 0.6/1kv.

It has the main characteristics of fire-resistant cables. The cables are not easy to catch fire or continue to burn only within a certain range. It is suitable for power stations, subways, tunnels, high-rise buildings, and large-scale

Dense distributed cables in industrial and mining enterprises, oil fields, coal mines and other places.

Technical performance of the power cord

1. The maximum temperature rating of the PVC insulated cable conductor is 70°C. When a short circuit occurs (the longest duration does not exceed 5S), the conductor temperature does not exceed 160°C.

2. The maximum rated temperature of the conductor of the XLPE insulated cable is 90℃, short circuit occurs (the longest duration does not exceed 5S), and the conductor temperature does not exceed 250℃.

3. When installing PVC insulated or sheathed cables, the ambient temperature should not be lower than 0℃.

4. Perfect chemical stability, resistance to acids, alkalis, oils and organic solvents, and flame retardants.

Advantages of power cables.

1. It occupies a small area. It is usually buried in the soil or placed indoors. In ditches and tunnels.

The insulation distance between the lines is very small, no tower is used, less land is occupied, and no ground space is basically occupied.

2. High reliability. Affected by weather conditions and surrounding environment, the transmission performance is stable and the reliability is high.

3. It provides more favorable conditions for the development of ultra-high voltage and large capacity such as low temperature and superconducting cables.

4. Large distributed capacitance.

5. Less maintenance workload.
6. The possibility of electric shock is small.
