I. Product Introduction

HZ - A52 trolley- type cable fault testing system is a product of our company's long-term commitment to power cable fault testing. To meet the rapid development of the power industry, it highly integrates traditional, independent cable fault location measurement, an integrated power frequency high-voltage power supply, a multi-pulse generator, and automatic discharge into a single trolley-type cable fault testing system. The system features a compact and safe high-voltage design with embedded distance measurement units , and strong anti-interference capabilities. This system is used for measuring the distance to various power cable faults . The testing software automatically identifies the fault location and reads the distance, making cable fault testing truly convenient, simple, efficient, and safe, providing ease of rapid testing for power cable faults.
