DY-800 type cable fault testing device, is used in modern classic DC-flash method, the impact high-voltage inductance sampling method, the impact of high-voltage current sampling method, low voltage pulse, and many other test methods for various types of power cable short-circuit fault, open circuit failure, high- resistance flash failure, high- resistance leakage failure, and other kinds of failure to failure analysis, testing. At the same time the machine can also control cables, coaxial cables and telecommunications cables, the city appears short circuit, open circuit fault for the early detection, can also link cable for proofreading.
