The fastening bolt 203 is manually rotated to install and test the cable. The middle part of the cable is then placed into the conductive solution. During use, the hole control switch 303 is activated, and the circuit is energized through conductive wire 1 302 and conductive wire 2 304, which illuminates the indicator light 305. The voltage in the conductive solution is continuously detected by the voltmeter 204. If the voltage increases, it indicates that the cable is leaking current, which means that the cable insulation layer is damaged or has a through hole. If no voltage change occurs, it indicates that the insulation performance of the cable insulation layer is good, which facilitates the detection of the cable insulation layer and improves the effectiveness of the detection device.
