Summary:

A cable used for transmission and distribution of electrical energy. Commonly used in urban underground power grids, power generation lines, industrial and mining enterprises internal power supply. In electric power lines, the proportion of cables is increasing. Power cable is a cable product used to transmit and distribute high-power energy in the main line of power system, including 1-500 kV and above various voltage levels. According to the voltage level, it can be divided into medium and low voltage power cables (35 kV and below), high voltage cables (110 kV or above), ultra-high voltage cables (275-800 kV) and ultra-high voltage cables. Cables (1000kV and above)

Medium-voltage power cable

High- and low-voltage crosslinked cable

purpose
The cable are used in power transmission and distribution systems with rated voltages of 0.6/1, 1.8 /3, 3.6/6, 6/10, 8.7/15, 12/20, 18/30, 21/35, and 26/35 kV.
Technical performance

1. The cable laying temperature: ≥0°C; the cable shall be heated in advance at the temperature lower than 0°C.

2. The long-term allowable operating temperature of the cable conductor: ≤90°C.

3. In case of short circuit (the maximum duration not more than 5 seconds), the maximum operating temperature of the cable: 250°C.

4. The allowable bending radius of cable:

Single-core cable: [20 (D+d) + 5%] (mm)

Multi-core cable: [15 (D+d) + 5%] (mm)

D ............... Actual outer diameter of cable (mm)

d ............... Actual outer diameter of cable conductor (mm)

5. Laying drop:。
Cable laying is free from horizontal drop.
