Description
Overview
GAOTek Power Cable Fault Detectors are a new generation of portable cable designed and manufactured by our company according to user requirements and considered from the field. They adhere to our consistent high-tech, high-precision, high-quality purposes, to raise the level of cable testing to a new level. The whole cable fault tester consists of three parts: flashing, tracing and locator. They can be used to detect various types of electricity: the low resistance, high resistance, short circuit, open circuit, leakage fault and flashover fault of the cable can accurately detect the fault location and power of the underground cable. They have the characteristics of accurate test, high intelligence, wide adaptability, stable performance, light weight and portability.
