II. Product Features:

1. The Cable Fault Detection Tester HZXT-710 is fully functional, and tests faults safely, quickly, and accurately. The instrument uses low-voltage pulse method and high-voltage flashover method to detect various cable faults, especially for cable flashover and high-resistance faults, which can be directly tested without burning through. If equipped with an acoustic pinpointing device, it can accurately determine the exact location of the fault.

2. High test accuracy: The instrument adopts high-speed data sampling technology with an A/D sampling speed of 100MHz, giving the instrument a reading resolution of 1m and a detection blind zone of 1m.

3. High intelligence: Test results are automatically displayed as waveforms and data on a large-screen LCD, making fault judgment intuitive. It also comes with a full Chinese menu display operation function, requiring no special training for operators.

4. It has waveform and parameter storage and recall functions, using non-volatile devices, so waveforms and data are not lost after power-off.

5. It has dual-trace display function, allowing comparison of the fault cable test waveform with the normal waveform, which is helpful for further fault judgment.

6. It has waveform expansion ratio function; changing the waveform ratio can expand the waveform for precise testing.

7. The position of the dual cursors can be changed arbitrarily, directly displaying the direct or relative distance between the fault point and the test point.

8. It has the function of modifying the propagation speed according to the different cable under test.

9. Small portable shape, built-in rechargeable battery power supply, convenient to carry and use.

Cable Identifier

The Cable Identifier is a special instrument used to identify a specific cable from a bundle of cables during power cable installation, migration, maintenance, and fault handling. When identifying a specific cable, it uses both the current direction and the current amplitude as judgment criteria. This dual judgment standard can more reliably and accurately identify cables. The instrument is a miniaturized portable, compact device, packed in an aluminum alloy case, consisting of a generator, a receiver with a clamp, and connecting wires.

Technical parameters

Instrument power supply: The Cable Identifier host is powered by AC 220V, and the receiver is powered by a 9V battery.

The clamp is a current transformer with an inner opening size of 120mm. A voltage is induced in the clamp, the amplitude of which is determined by the current intensity, and its polarity is determined by the current direction.

Remote-Controlled High-Voltage Cable Safety Piercing Device

For many years, cable operation and maintenance departments have performed cable piercing according to the requirements of Article 234 of industry standard DL409-91, using manual piercing. Once the cable identification is wrong, mistakenly piercing a live cable will cause great harm.

Our company has launched the HZ-2015C remote-controlled high-voltage cable safety piercing device, a supporting product of the HZ-2015S cable identifier, which completely solves the problem of safe on-site piercing and eliminates the occurrence of unsafe accidents.
