Concentric Conductor Power Cable
■ Application
The product is suitable for electric power transmission and
distribution network circuit with rated voltage 0.6/1kV and including.
■ Product Characteristic
1. It has lower and uniform positive (inverted) sequence and zero sequence impedance, which can
improve the quality of electricity supplied.
2. Comparing with the fourth core of common 4-core cable, the reactance value of concentric
conductor is much lower than the working condition of zero sequence, which can improve
sensitive action of short-circuit auto-protection device and can ensure cable and relative equipment
for safe operation.
3. It has strong properties of anti-electromagnetic interference and anti-thunder strike.
4. Five-core cable is suitable for power supply of TN-S and TN-C-X system.

■ Technical parameter
1. D.C. resistance of conductor is referenced to the cable with PVC insulation and sheath.
2. The finished cable shall be subjected to A.C. voltage of 50Hz 3500V 5min and result should not be breakdown.
As far as single core is concerned, it should make voltage resistant test after immersing water.
3. DC resistance value at 20℃.
