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 sequenceimpedance, which can
1.It has lower and uniform positive (inverted) sequence and zero sequenceimpedance, which can
improve the quality of electricity supplied.
2.Comparing with the fourth core of common 4-core cable, the reactance valueof concentric
conductor is much lower than the working condition of zero sequence, whichcan improve
sensitive action of short-circuit auto-protection device and can ensure cableand relative equipment
for safe operation.
3.It has strong properties of anti-electromagnetic interference andanti-thunder strike.
4.Five-core cable is suitable for power supply of TN-S and TN-C-X system.
