聚氯乙烯绝缘聚氯乙烯护套控制电缆

本电缆参照采用IEC502-1983标准生产,电缆固定敷设在额定电压0.6/1kv及以下的输配电线中。电缆导体长期最高工作温度不超过70℃。
短路时(最长持续时间不超过5秒)电缆导体的最高温度就不超过160℃。敷设电缆时的环境温度应不低于0℃,其最小弯曲半径不小于电缆外径的10倍,电缆落差不受限制。

PVC insulated and sheathed Power Cables are manufactured in accordance with the Standard IEC502-1983.These cables are used for the power transmission and distribution circuits rated voltage up to and including 0.6/1kv for fixed installation.
The maximum permissible continous operating temperature of the conductor shall not exceed 160℃.
The maximum rated conductor temperature at short-circuit (5 S maximum duration )installation temperature,Ambient temperature shall not lower than 0℃.
Bending radius of cable shall mot smaller than 10 times of its external diamerter.
It is not restricted by the differece of level along the route during installation.
