Product Details

power cable is used for transmission and distribution of electric energy cable, power cable is often used in urban underground power grid, power station lead-out line, industrial and mining enterprises internal power supply. Power cable is a cable product that transmits and distributes high-power electrical energy in the main line of the power system, including 1-500KV and above various voltage levels and various insulated power cables.

1. product name/applicable voltage

(0.6/1kv): XLPE insulated power cable

main raw materials: copper-aluminum conductor, cross-linked material (XLPE) insulation, PVC sheath

2. product implementation standard

cable design meets the requirements of national standard GB/T12706-2008 and International Electrotechnical Commission recommended standard IEC60502.

3. products use

XLPE insulated cable conductor normal operating temperature is 90 ℃, XLPE cable not only excellent electrical performance, with high working temperature, transmission capacity, but also has the advantages of simple structure, small diameter, light weight, easy installation and use, laying drop without restrictions. Widely used in industrial and mining enterprises and urban power grid.

4. scope of application

power cable scope of application: laying in indoor, outdoor, pipeline, cable trench and loose soil, can withstand a certain laying traction, but can not withstand the mechanical external force of the occasion, single core cable is not allowed to be laid in the magnetic pipe.

5. product use characteristics

1. The ambient temperature during laying is not lower than 0 ℃ (when it is lower than 0 ℃, it should be heated in advance), and the drop of the cable is not limited.
2. The minimum bending radius during laying and installation is specified as follows: unarmored single-core cable: 20D; Unarmored three-core cable: 15D; Armored single-core cable: 15D; Armored three-core cable: 12D;(Where D is the actual outer diameter of the cable)
3. Operating temperature of the cable: PVC sheath shall not exceed 90 ℃;
4. Overload temperature: the maximum overload temperature when the cable is short-circuited is 130 ℃;
5. The maximum rated temperature of the cable conductor is 90 ℃, and the temperature of the conductor when short-circuited (the longest lasting 5s) does not exceed 25 ℃.
