Underground High-Voltage Cable Fault Locator

Product features:

This product adopts a professional-grade signal emission system, which can stably transmit detection signals through high-voltage cable insulation layers, even for high-resistance grounding faults that are difficult to detect by ordinary testers. The ±1m positioning accuracy ensures that maintenance personnel can accurately find fault points without large-scale excavation. The IP65 dust and water protection rating makes it suitable for outdoor long-term operation in various weather conditions. It supports 4G and WiFi wireless data transmission, allowing on-site test data to be uploaded to the backend management system in real time for team collaboration and remote expert guidance. The matched inductive detector can accurately track the signal path of the cable, helping to lock the exact location of the fault point quickly.

Product specifications:

The locator has a detection range of 0-50km, with a positioning accuracy of ±1m. It supports detection of high-resistance grounding, broken cable and flashover fault types. The host is equipped with a 7-inch high-definition LCD screen with a resolution of 1024*768, displaying fault distance, signal strength and analysis results in real time. The host dimensions are 320*240*180mm, with a weight of 5.8kg. It supports two power supply modes: AC 220V mains power and DC 12V external battery, meeting the needs of different on-site power supply conditions. The protection rating is IP65, and the operating humidity is ≤90%RH without condensation. It supports 4G and WiFi wireless data transmission, and can export test data via USB interface. The matched inductive signal detector has a detection sensitivity of 0.1mV, suitable for tracking weak cable signals.

Product application:

This underground high-voltage cable fault locator is mainly used for fault detection of urban power grid high-voltage buried cables, suburban power transmission lines, railway signal cables and other underground high-voltage cable systems. It is suitable for professional power grid maintenance teams, public utility construction companies, railway maintenance departments and other professional institutions. By accurately locating fault points without destructive excavation, it reduces maintenance costs and shortens power outage time, ensuring the stable operation of urban and industrial power supply systems.
