2.1Rated voltage U0/U should be 450/750~600/1000V
U0~valid of the voltage between main insulated conductor and earthing (metal shield ,metal sheath of environment dielectric).
U~vaild of voltage between any two phase conductor in multicourse cable or single core cable system.
when AC.System is applied ,the rated voltage of cables should be at least equal to the nominal voltage of the system .When DC.System is applied ;the nominal voltage of this system should not be more than the rated voltage of the system by 1.5 times.
2.2 The permitting long-term operating temperature of cable conductor should be PVC insulation :70℃
