PVC insulted PVCsheathed electric cable (flame retardant type)
Usage:
Cores number: (1~5) cores　　　Nominal cross-sectional area: (1.5~630mm2)
Standards:
The cable is manufactured according to GB12706-91 or IEC60502. It is suitable to be installed in the four wires system with rated voltage of 0.6/1KV (Uo/U) for transmitting electricity
Operating characteristics:
The maximum operating temperature of cores shall not exceed 70℃when the cable is used for long period. The temperature of cores shall not exceed 160℃at short circuit for 5 seconds .The ambient temperature should not be below 0℃during installation. The minimum-bending radius shall not be less than 10 times of the cable diameter when lying. The single cable should not be laid in magnetic ducts when it is electrified with alternating current.
