Concentric conductor power cable

1Concentric conductor power cableScope of Application
This product is suitable for transmitting electrical energy in power lines with a rated voltage of 0.6/1kV and below.
2、 Product Features
1. Having low and uniform forward (reverse) and low sequence impedances is beneficial for improving power supply quality.
2. The reactance value of the concentric layer conductor is much lower than that of the fourth core of a regular four core cable in low sequence operation, which is conducive to the sensitive action of the short-circuit automatic protection device and ensures the operation of cable related equipment.

3. Has strong resistance to electromagnetic interference and lightning strikes.
4. The five core conductor power cable is suitable for three-phase five wire distribution systems.
3、 Model specifications
1. Meaning of letters
-T: Concentric conductor ZR: flame retardant NH: fire-resistant (the rest are the same as ordinary power cables)
4Concentric conductor power cableTerms of Use

1. The long-term allowable working temperature for conductors is 70 ℃ for PVC insulation;
Cross linked polyethylene insulation at 90 ℃.
2. When a cable short circuit occurs (lasting for no more than 5 seconds), the high temperature of the conductor should not exceed:
PVC insulated cable at 160 ℃;
Cross linked polyethylene insulated cable at 250 ℃.
3. The ambient temperature during installation should not be lower than 0 ℃.
4. The allowable bending diameter of the cable is not less than 40 times the outer diameter of the cable for a single core cable;
Multi core cables shall not be less than 30 times the outer diameter of the cable.
5. Flame retardant and fire-resistant cables meet the corresponding requirements for flame retardant and fire-resistant performance.
