The Communication Cable Fault Tester mainly consists of four key components: the cable fault tester main unit, cable fault locator, cable path tracer, and a special ultra-light high-frequency high-voltage power supply for cable fault testing.The complete set of communication cable fault testers can quickly and accurately locate fault points in various cables when used together. It is suitable for a wide range of applications in industrial and mining enterprises, metallurgy, petrochemical systems, power plants, airports, railways, and power supply departments.
Product Applications
The cable fault tester main unit is used to measure the nature of cable faults, the total length of the tested cable, and the approximate location of the fault point from the testing end. The cable fault locator is used to determine the precise location of the fault point based on the approximate position identified by the main unit. For buried cables with unknown routes, the cable path tracer is used to determine the underground cable path. If the specific route of the underground cable is already known, the cable path tracer may not be necessary. The cable fault tester main unit can be directly connected to a laptop for easy management and operation. The communication cable fault tester is widely used for detecting low resistance, short circuits, open circuits, and various high resistance faults in aluminum-core or copper-core power cables of different cross-sections, high-frequency coaxial cables, and local telephone cables below 35KV. It is an essential device for ensuring safe power supply and a powerful assistant for cable production and maintenance workers.

Cable Fault Locator Performance Introduction
The cable fault locator is equipped with first-class integrated circuits and amplifiers. The filtering device on the sound channel of the cable fault locator instrument maximizes the removal of interfering noise while enhancing the sound generated by the arc. The LCD screen can simultaneously display sound pulses and magnetic pulses, as well as the distance from the fault point to the probe test point. This allows for the joint determination of the fault point by listening to changes in underground sound and displaying the distance.
