聚氯乙烯绝缘和护套控制电缆
聚氯乙烯绝缘聚氯乙烯护套控制电缆，适用于凉额定电压450/750v及以下控制、监控回路及保护线路等场合使用。电缆线芯的长期允许工作温度为+70℃。
电缆的敷设温度不低于0℃，推荐的允许弯曲半径为不小于电缆外径的6倍。
The PVC insulated and sheathed control cables are
used for the controlling,monitoring and protecting circuit system
rated voltages up to and including 450/750v.The max permissible
continuous poerating temperature of the conductor shall be +70℃.
During installation the min ambient temperature shall be above 0℃
and the bending radius of cable shall not less than 6 times of its
external diameter.
