The XHHV535-4TSB cable fault location system is used to detect the main insulation fault of power cables with voltage levels of 35kV and below and calibrate the cable length. This system consists of two parts: a cable fault tester and a high-voltage pulse generator.
The cable fault tester adopts a simple operating software interface, centralized control by a single-chip microcomputer,touch-type operation, and a built-in large capacity lithiumion battery. It is stable, reliable, and easy to use. An independent power supply and power supply system are used to prevent power supply interference during impact discharge.
This cable fault test system is suitable for low-resistance, short-circuit, open-circuit and broken wire faults of power cables,high-frequency coaxial cables, street light cables, and underground wires of various materials with different cross-sections and different media, as well as high-resistance leakage and high-resistance flashover faults.
