1.Cu/PVC/PVC flame resistant power cable 2.Used for construction,building 3.Made by ZMS cable
Cu/PVC/PVC flame resistant power cable
Application: This peoduct is used in the environment with high demnd on fire-resisting performance such as high-rise building,Power station,power plant,mine,chemical industry,subway,and so on,also the necessary cable prepared for emergency power,fire-fight pump,and communication system of elevator,in time of being directly fired by flame,it could ensure contnually supplying power andtransmtting signal to keep lighting within certain time for people to retreat safely and also to benefit fighting fire to lower damage.
Voltage: 450/750V
Conductor: CU
Insulation & sheath: PVC (Premature Ventricular Contraction)
Executive standard
1)GB/T12706.1-2002(Equivalent IEC 60502)
Rated voltage 1kv (Um=1.2kv)and power cable
2)GB/T12706.2-2002(Eqquivalent IEC60502-2)Rated voltage6 kvUm=7.2kv and Um=36kv power cable
3)G/BT12706.3(VOLTAGE Grade Overtep IEC 60502-2) Rated Voltage3.5V Um=40.5kv and power cable.
Working consitions:
1) This maximum working temperatuie of thr conductor temperature is +90.
During having a short (lasting less than 5 seconds )the maximum temperature of the cable conductor shall not be above +250
Environment temperture should be no lower than+0 for laying the cable.
2) Bending radius allowance of the cable:
Single core cable:No steel tape cable 20D,steel tape cable 15D
