APPLICATIONS:
It is used for power transmission on power lines of rated voltage 0.6/1kV or lower. It is widely used in petrochemical industry, metallurgy, mines and
high-rise buildings.
STANDARD:
IEC 60502-1
MAIN FEATURES:
1) Cable main conductor has low and even proper (inverse order) and zero order impedance, which benefits quality improvement for power supply.
2) Concentric conductor has the lower zero preface resistance. This benefits the sensitive action of automatic protection devices in short circuit and ensures safe operation of cable and concerned devices.
3) Cable has strong resistant characters against electromagnetic interference and thunder strike.
WORKING CONDITION:
1) The tallest work temperature of the cable conductor:
PVC insulation is 70ºC.
XLPE insulation is 90ºC.
2) Short-circuit time (Continuously time is not over the 5s), The temperature of the conductor do not exceed:
PVC insulation is 160ºC.
XLPE insulation is 250ºC.
3) The minimum bent radius of the cable:
Single core is 20D, Many core 15D.
