Description
Overview
GAOTek underground cable fault locator is cable communication, and electric transport completely relies on the good condition of the cable circuit. Once the circuit breaks down without punctual examination and repair, it will undoubtedly trigger mass economic loss and bad social influence. The electric fault-measuring testing instrument is a very important tool. The intellectual testing instrument uses multiple testing methods. It adopts the most advanced electronic devices and with computer and special electronic technology, combining our company’s successful experience long time exploitation on cable fault measuring testing instruments and is absolutely of high tech, intelligence and abundant functions. Our cable fault detector is a testing device of good integrity. It can test on the High Resistance Flashover Fault, Grounding High and Low Resistance Fault, Short and off Circuit on the Cable Fault Poor contact etc. If it is equipped with a sounding method and locating instrument, it can exactly detect the fault point. Furthermore, it applies to tests for various power and communication cables.
