KD-216B power cable fault comprehensive tester is a portable intelligent cable fault detection instrument designed and manufactured by our company. The instrument is composed of a highly intelligent industrial touch screen integrated computer, a data collector with USB interface, a high-efficiency polymer battery and a charging adapter and accessories. The instrument is small in size, light in weight, easy to use and easy to carry.

1. It can test various types of copper-aluminum core power cables, coaxial communication cables and local telephone cables with voltage levels below 35KV, such as open circuit faults, short circuit faults, high-resistance flashover faults and high-resistance leakage faults.
2, with a variety of test methods, such as low voltage pulse method, impact high voltage current sampling method, DC high voltage flashover method, multiple pulse method, etc.
3, the instrument uses high-efficiency polymer rechargeable battery power supply, sample interface for USB type direct microcomputer power supply. Coupled with high new current sampling technology, the system can truly isolate operators and testers from high voltage, strong anti-interference ability, and ensure test reliability and man-machine safety.
4, pre-sampling measurement unit adopts high new signal processing technology, Chinese screen display, the test waveform characteristics are clear and easy to distinguish, making the cable fault analysis easier to master.
