阎倩昭4202低压三相之间最低阻值是多少 -
颜朱河19785508737 ______ 电缆的相间绝缘电阻值与电缆的种类、电压等级、电缆绝缘的温度、空气湿度、环境粉尘的性质以及电缆的使用年限有关. 如:聚氯乙烯绝缘聚氯乙烯护套电力电缆,20℃条件下,额定电压1kV,即电压电力电缆,每千米长度的绝缘电阻一般最低值不小于40MΩ.‍

阎倩昭4202低压电线和电缆线与线之间的绝缘电阻值必须大于多少;为什么
颜朱河19785508737 ______ 绝缘电阻必须大于0.5兆欧,绝缘电阻小容易引起漏电,击穿,保护器跳闸.

阎倩昭4202电缆相间阻止最小多少 -
颜朱河19785508737 ______ 是问电缆的相间的绝缘电阻的最小值吗?若是这样: 根据GB50303-2011《建筑电气工程施工质量验收规范》中的18.1.2 条的强制项目: 低压电线和电缆,线间和线对地间的绝缘电阻值必须大于0.5MΩ.

阎倩昭4202低压相间绝缘电阻值一般多少为合格 -
颜朱河19785508737 ______ 0.5 MΩ为合格.

阎倩昭4202YJV22低压电缆0.6/1KV的电缆相间绝缘电阻一般是多少? -
颜朱河19785508737 ______[答案] YJV22低压电缆0.6/1KV的电缆相间绝缘电阻用1000V摇表测试只要大于1MΩ即可.

阎倩昭4202YJV22低压电缆0.6/1KV的电缆相间绝缘电阻一般是多少? -
颜朱河19785508737 ______ YJV22低压电缆0.6/1KV的电缆相间绝缘电阻用1000V摇表测试只要大于1MΩ即可.

阎倩昭4202电缆绝缘合格标准 - 关于测量绝缘!请问用摇表测电缆绝缘时,电阻值>=多少表示电
颜朱河19785508737 ______ 你好! 《电力设备预防性试验规程》规定: 绝缘电阻试验:低压电缆或400V电缆用500-1000V兆欧表;要求:大于2MΩ. 低压电缆不须测量吸收比.

阎倩昭4202低压照明电线线与线之间的绝缘是多少为准
颜朱河19785508737 ______ 低压照明电线线与线之间的绝缘,火线与火线、火线于零线之间必须大于0.5兆欧姆,保护地线与地之间要小于10欧姆.

阎倩昭4202低压电缆破损修复后绝缘阻值的标准?另外低压电缆绝缘最低标准是多少啊? -
颜朱河19785508737 ______ 低压电缆修复后没有高压电缆的8项测试,只需确认电缆的耐压承受电流流量的能力,主要是两相之间的绝缘水平,一般电缆修复后,绝缘水平大大降低,建议如果负载较大,经济条件允许的话,更换一下线路;如果还要用,可在断路处加接绝缘端子进行保护

阎倩昭4202低压电线四芯,24V电压对电线绝缘要求 -
颜朱河19785508737 ______ 一般24大部分直流电,绝缘性要求较低,0.5平以上即可
