Cable breaking point finding method

The method how to find the cable cut point is a kind of strong technology work. It need to combine various methods and devices to perform operations based on the specific fault type and site conditions. The following is common method how to find cable cut point.

Digital multi-meter method: First connect the cable with the break point to the fire-line, place the pen perpendicular to the wire, press and hold the "Sensing breaking point Test" button to move slowly forward on the wire, the pen will make a sound when it detects a break point.In addition, you can also use a digital multi-meter for measurement. If the multi-meter displays intermittently on and off, this is the breaking point.

Needling test method: Insert the steel needle into the broken cable in sections, use a multi-meter to determine the cable break point by measuring the connection between the steel needle and the cable end. However, this method may damage the insulation layer, so it may cause other problems in later cable use, especially in environments with high humidity.

Pull-out cable test method: use a vise to pull out the broken cable end. If the break point is near the cable end, the insulation is easy to break.This method is used for the breaking point near the end of the cable, such as the drive control button cable.

These are some commonly used cable breaking point search methods. It should be noted that, because the cable fault may be caused by external damage or product quality problems and other reasons, so in the actual operation also need to have enough experience and skills.
