The automatic testing method of cable fault is characterized by that the pulse signal transmitted and received by pulse reflection test circuit can be directly superposed on the output end of d.

电缆故障的自动测试方法，其特征在于是将脉冲反射测试电路发射与接收的脉冲信号直接叠加到直流高压测量电路的输出端，直流高压测量电路的输出端与被测电缆端口连接。

It can test the corresponding ports rapidly, identifying each conductor in the cable. At the same time, it can find the faults of cable, such as short-circuit, broken-circuit and so on.

这个工具可以快速地对施工中的多芯电缆两端相对应的端口进行测试，并进行识别，同时也能够发现电缆中芯线的短路，断路情况。

Yielding strength test: Cable shall not cause circuit breakdown, and cause short circuit between the conductor after tested by 15000 times return movement i. e. 30000 times of single route movement.

曲挠试验：在试验期间经15000次往复运动，即30000次单程运动后不发生电流断路，也不发生导体之间的短路。
