Portable digital Underground 35KV Cable Distance Test Cable Fault Locator

ZX-A10 cable fault tester

ZX-A10 CABLE FAULT LOCATOR integrated industrial embedded computer platform, Network Communications Service and USB communication system. The device consists 3 parts: main system, fault locator and cable line tester. It is used for cable fault location, cable line and depth test and daily maintenance of cable data. It can also be used for signal cable fault location for railway station and airport.

Features:

1. Embedded computer system into cable fault locator. Lithium-power supply for convenient field tests.
2. 12.1 inch touch-screen and windows XP system.
3. USB interface. 5 sampling frequency between 6.25 MHz to 100MHz for cable of different length.
4. Auto earch fault point and display the distance, the movement of double cursor can be accurate to 0.15m.

5. The waveform can be compressing or expanding freely.

6. System display two waveforms randomly which is close to standard waveform for your reference.
7. Total 40G waveforms and on-site wiring diagrams for your reference
8. Smart modular sampler to replace the on-site wiring, sampling totally separated with HV to ensure safety.

Application:
1. Test cable fault for different voltage levels, different sections and different medium, including open circuit, short circuit, low resistance, high resistance leakage, high resistance failure flashover.
2. Testing signal cable fault for railway station, airport.
3. Testing wave propagation speed of the cable which length is known.
4. Testing the cable route and depth.
