Concentric Power Cable
Concentric power cables are used for power transmission on lines with rated voltage 0.6/1kV or lower. They are widely used in the petrochemical industry, metallurgy, mines, and high-rise buildings.
The concentric cable is built as per company standard.
Main features
1. Cable main conductor has even negative and zero sequence impedance, which is a significant improvement in power supply.
2. Concentric conductor has the lower zero sequence impedance. This benefits the sensitive action of automatic protection devices in short circuit and ensures safe operation of cable and concerned devices.
3. Coaxial cable has strong resistant characters against electromagnetic interference and thunder strike.
The usage characteristic of the cable
1) The maximum working temperature of the cable conductor:
PVC insulation is 70℃.
XLPE insulation is 90℃.
2) In case of a short (lasting less than 5 seconds) the maximum temperature will not exceed:
PVC insulation 160℃.
XLPE insulation 250℃.
3) The minimum bent radius of the cable:
Single core is 20D, Many core 15D.
