用于交流额定电压450V 750V及以下控制监控回路及保护线路等场合。
一、产品介绍
KVV 2×0.75- 4×6(铜芯聚氯乙烯绝缘聚氯乙烯护控制电缆)用于交流额定电压450V/750V及以下控制监控回路及保护线路等场合。其中屏蔽型控制电缆,由于具有良好的评比性能得到电厂、电站的大量使用,电缆意义敷设在市内、电缆沟、管道、直埋、竖井等能承受较大机械拉里的固定场合。
二、使用特性
1、电缆导体的长期允许工作温度为70℃。
2 、电缆的敷设温度应不低于0 ℃,推荐的允许弯曲半径:无铠装层的电缆,应不小于电缆外径的6 倍。有铠装或铜带屏蔽结构的电缆,应不小于电缆外径的12倍。有屏蔽层结构的软电缆,应不小于电缆外径的6 倍。
