针对传统的甩开或封连使用中电缆芯线进行核对电缆信道所存在的不安全因素,提出了采用500伏兆欧表的检测方法,大大提高了核对线缆的安全系数和工作效率。
In view of the unsafe factors of checking the cable channel by using the traditional cable core in throw-off or sealing connection, a method of detecting 500-volt megohmmeter is proposed, which greatly improves the safety factor and working efficiency of checking the cable.
