Product Description

 Pro Underground Cable Fault Pinpointer XHGX507

The XHGX507 Pro Underground Cable Fault Pinpointer is a professional-grade electromagnetic induction detection system engineered for precise underground cable fault location. It excels at pinpointing cable-to-ground insulation faults up to 2MΩ using advanced step voltage detection technology, eliminating the need for high-voltage flashover equipment. Designed for street lighting cables, buried power distribution cables, and communication cable networks.

Key Features

  • Step Voltage A-Frame Fault Detection: Proprietary step voltage detection method pinpoints cable-to-ground insulation faults up to 2MΩ without high-voltage equipment. The A-frame accessory measures potential differences along the cable path to locate the exact fault point with zero potential crossing detection
  • 2MΩ High-Resistance Fault Capability: Uniquely designed to locate high-resistance cable insulation failures that traditional time-domain reflectometry (TDR) and high-voltage surge methods struggle with. Ideal for single-phase metallic ground faults where discharge energy is insufficient for acoustic pinpointing
  • All-Digital LCD Display System: Large backlit LCD screen displays real-time signal strength ladder diagram (0-999), numeric value, gain level (0-100dB), frequency mode, battery status, and depth/current measurements. Voice FM tone prompt reduces operator eye fatigue during extended field work
  • Dual-Frequency Transmitter: Low Frequency (LF) for long-distance tracking up to 15km with minimal adjacent line interference, and Radio Frequency (RF) for high-resistance pipelines and poor grounding conditions with automatic impedance matching (5Ω-3000Ω)
  • Three Signal Application Methods: Direct connection for strongest signal and optimal accuracy; Coupling clamp for live (charged) cable detection without service interruption; Built-in induction antenna for areas where cable access is physically limited
  • Three Receiver Working Modes: Peak method for fast cable tracking, Trough method for precision positioning in low-interference environments, and Step Voltage method with A-frame for fault pinpointing
  • 50Hz Passive Detection: Locate energized power cables by detecting their natural 50Hz frequency emission — no transmitter connection required, ideal for pre-excavation utility surveys
  • Depth and Current Measurement: Direct-reading digital depth display (up to 10m), plus 45-degree and 80% verification methods. Real-time current measurement distinguishes target cable from parallel adjacent pipelines even at different burial depths
  • Built-in Ohmmeter: Automatic loop resistance measurement and continuous auto-output impedance matching ensures optimal signal transmission regardless of soil conditions or cable type
  • Portable Field-Ready Design: Receiver 70cm × 20cm × 11cm (3kg), Transmitter 16cm × 16cm × 39cm (4kg). Both powered by rechargeable 7.4V lithium batteries. LCD backlight for night operation. Operating temperature range -10°C to +55°C

The XHGX507 is a reliable cable testing solution with accurate results and stable performance. It has helped our team locate cable issues faster and improve maintenance efficiency. The only areas that could be improved are the learning curve for new operators and adding more language options for international users. After proper training, the equipment is easy to use and performs very well in field applications

We have been using the XHDD503 for cable fault detection and maintenance work in our distribution network projects. In cities like Bengaluru, where underground cable systems are widely used in commercial and residential areas, quick fault identification is very important for reducing outage time. The XHDD503 has helped our team improve the efficiency of cable testing. The measurement results are accurate, the waveform display is clear, and it helps engineers locate fault points faster during emergency maintenance operations. We also appreciate its portable design and simple operation. Our technicians can carry the equipment easily to different job sites and complete testing work more efficiently. One area that could be improved is that new operators need some training before they can fully understand all testing functions. Also, adding more local language options would be helpful for some technicians. Overall, the XHDD503 is a reliable and cost-effective solution for cable maintena
