I. Overview

Our export-type vehicle-mounted intelligent cable fault location system is a high-performance device developed by our company to keep pace with the development trends of the international power industry and meet the dynamics of rapid power development. Designed to meet the needs of power cable operation and maintenance sites, it integrates a complete set of cable fault testing functions. The entire system is designed with an integrated approach, eliminating the need for vehicle transport during export. This allows for flexible vehicle selection and portable installation in the destination country.

The entire system meets the General Technical Conditions for Special Testing Instruments for Power Equipment as specified in the People's Republic of China power industry standards DL/T849.1-2019 ~ DL/T849.3-2019. It is used for testing various faults in power cables, and its functions cover accurate testing of faults in power cables, railway and airport signal control cables, and street light cables.

1.1 Product Features

Through continuous development and innovation, the product possesses the following characteristics: 

 basis for cable installation, maintenance and management .

 Wave velocity verification: By verifying the signal propagation speed in the cable, the accuracy of fault location can be improved.

 Based on the principle of multiple pulses, various power cable main insulation faults can be pre-located.

 Embedded design, Chinese interface, stable operation.

 It adopts distributed control bus technology, which has a high degree of automation, is simple to operate, and is convenient for testing and wiring.

 The output high-voltage pulse frequency is controllable, and the impact energy is large, meeting the requirements for pre-positioning and precise positioning.

 DC high voltage output, continuous high current burn-through, rapid carbonization of high resistance fault points (such as water inlet cables).

 It provides a stable output of 2,048J of high impact energy, making it particularly suitable for internal faults in high-resistance connectors.

 Used for conducting cable withstand voltage tests, efficiently detecting cable insulation performance and potential faults .

 It features a grounding protection safety monitoring system , a test site video monitoring system , and step voltage safety protection and self-testing functions , ensuring the personal safety of operators to the greatest extent possible.

 Optional wireless walkie-talkies can be equipped to enable timely communication between the fault location site and vehicle personnel, and to quickly handle abnormal situations.
