Question: How much is the price of the cable fault tester? Answer: 1. It can test various faults of copper, aluminum core power cables and local telephone cables of various models and different voltage levels. Common oil-invaded paper cables, cross-linked vinyl cables, non-drip cables and plastic cables: how much is the price of the cable fault tester? Answer: 1. It can test various types of copper, aluminum core power cables and local telephones with different voltage levels Various faults in cables. The electric wave propagation speed of four common power cables, namely oil-infiltrated paper cable, cross-linked vinyl cable, non-drip cable and plastic cable, has been preset in the instrument, and the cable length and fault distance do not need to be manually converted, and are automatically converted and displayed by the instrument fault distance.

2. It can test open circuit and low resistance faults of various types of cables and high resistance flashover faults and high resistance leakage faults of power cables. 3. For simple open-circuit and short-circuit fault waveforms, the instrument can automatically analyze and automatically mark the fault point by double cursors, and display the fault distance without manual intervention. 4. Two waveforms (fault waveform and overall waveform) can be displayed on one screen during alliance, which brings great convenience to the same household to analyze waveforms.

5. The instrument software is completely standardized, and the instrument software can be copied to any PC. 6. The 3.5" floppy drive can be used to copy the field test waveform and send it to remote users through the network. 7. It has the functions of speed measurement (the propagation speed of radio waves in the cable) and time measurement (fault point echo time).

8. There are many test standard waveforms in the instrument memory, and the user can call up the learning reference at any time. 9. A variety of test methods can be used directly without adjusting the instrument itself. Product parameters 1. Test distance Single-ended test distance≤10 km 2. The shortest test distance (blind area): less than V/15 (m) Among them: the propagation speed of V wave in the cable under test 3. Test error Relative error:≤±2% error: the fault point is within a kilometer≤15 meters, the fault point is more than 1000 meters≤20 meters 4. Reading resolution: V/60 meters Among them: the propagation speed of V wave in the cable under test.

like:“Oil-impregnated paper cable”, the radio wave propagation speed is 160m/us, and the minimum resolution of the reading is 2.66 meters, that is, the reading changes by 2.6 meters every time the cursor moves on the screen. 5. Power supply: AC 220V±10% 50HZ6, environmental conditions Temperature: 0℃~50℃ Relative humidity: 80%±5% 7. Host volume: 350×250×200 (mm) 8. Mainframe weight: 5kg Technical indicators of cable line fault tester 1.
