Product Description

Cable Fault Detector

Darui Electric recommends

Structural features of mining cable fault detector:
1. The GHKLC mining type consists of a control part (low voltage) and high-voltage rectification, discharge, and inspection parts. Safe spaces are reserved between high and low voltage, and between high/low voltage and the casing.
2. To ensure the safety of equipment and personnel, high voltage initiation must be operated by a designated person with a key.
3. Each fault detection or cable inspection ensures that high voltage starts from zero and ramps up, with high and low voltage limit states. The voltage increase or decrease process is controlled by buttons, with smooth voltage change rates, making operation safe and simple.
4. The DC withstand voltage test time can be automatically controlled by a digital timer (or manually controlled), ensuring accurate and reliable test time.
5. Leakage current can be measured at any time as needed during the withstand voltage test process.
6. The equipment has overcurrent and short-circuit protection, with pre-start warning and overcurrent protection.
7. The control panel is equipped with power switch, high voltage start, high voltage interruption, voltage increase, voltage decrease switches or buttons, and a digital timer relay for withstand voltage test time.
8. The display panel has meters for high voltage, leakage current, and low voltage total current, with indicator lights for power, high voltage, timing, and a window for observing sphere gap discharge.
9. A dedicated high-voltage discharge rod is provided for discharging after each fault detection or test to ensure safety, with a grounding symbol at the bottom of the box.

Product Introduction of Mining Cable Fault Detector:

Mining cable fault detector: Coal mines are major users of cables. This device is based on the partial discharge method that does not damage the original layout of the cable, accurately detects the damaged part of the cable, and also has the function of testing after repair. Therefore, it is a reliable testing instrument for cable repair in coal mines. Coal mines are major users of cables. Due to the harsh underground working conditions, the annual damage of various cables is relatively large. To save costs and reduce production costs, each mine generally has its own cable repair team. However, due to the limitations of testing equipment and processes, fault detection and testing of repaired cables such as fully mechanized mining cables often do not meet expectations, and most use the forced breakdown method that causes significant damage to cable insulation. Based on the advantages of various testing instruments and the requirements for mining cables, our company has specially designed and manufactured a new generation of mining cable tester.
