Overview

GAOTek cable fault tester is suitable for measuring the low resistance, short circuit, and Open Circuit Broken Fault of power cables, high-frequency cables, local telephone cables, streetlamp cables, and buried wires with different cross-sections and different materials, and high resistance leakage and high resistance flashover failure. Under the mode of impulse current, it needs to work with high-voltage generator items. Under the multiple impulse mode, it also needs a coupler. After distance locating, the user could use items for fault pinpointing. These products can be combined into a set of high-performance and innovative cable fault testing systems.
