The XHHV535-4TSB cable fault location system is designed to detect main insulation faults in power cables with voltage levels up to 35kV and calibrate cable length. This comprehensive system includes a cable fault tester and high-voltage pulse generator.

The cable fault tester features an intuitive software interface with touch operation, centralized microcontroller control, and a built-in high-capacity lithium-ion battery. Its independent power supply system prevents interference during impact discharge, ensuring stable and reliable operation.

This system is suitable for detecting various faults in power cables, including low-resistance, short-circuit, open-circuit, broken wire, high-resistance leakage, and high-resistance flashover faults across different cable types and materials.
