Features :
This product not only has the characteristics of ordinary PVC insulated power cable and low voltage crosslinked power cable, but also has the following characteristics:
1. it has low and uniform positive (negative) sequence and zero sequence impedance, which is beneficial to improve the quality of power supply.
2. The reactance of concentric conductor is much lower than that of the fourth core of ordinary four-core cable under zero sequence. It is beneficial to the sensitive action of short circuit automatic protection device. So as to ensure the safe operation of cables and related equipment.
3. It has strong anti-electromagnetic interference performance and lightning strike resistance.
4. Five-core cable is suitable for power supply of TN-S and TN-C-S systems
