The HZD1401 Intelligent Pipe & Cable Locator is a high-performance underground cable and metallic pipe detection instrument independently developed by Wuhan Hongzhi Gaoce Electrical Technology Co., Ltd. The system consists of a transmitter and a receiver, integrating path tracing, cable identification, and fault pinpointing into one portable solution. It is widely used in power cable route surveying, non‑contact identification of energised cables, metal pipe (gas, water, oil) detection, pre‑excavation utility avoidance, sheath fault location, and low‑resistance/open fault location for low‑voltage cables.

• Path Tracing – Active and passive detection modes with multiple frequencies for precise underground route location.

• Depth Measurement – Supports real‑time depth, averaged depth, compass target method, 80%/70% method, and 45° method for various field conditions.

• Cable Identification – Works with a flexible clamp or stethoscope for positive identification of target cables in dense bundles, ensuring construction safety.

• Ground Fault Pinpointing – Using an A‑frame and a fault‑locating voltage booster, accurately locates insulation damage and sheath faults.

• Low‑Resistance & Open Fault Location – Audio induction method helps locate phase‑to‑phase shorts, sheath faults, and broken conductors.

1. Color Compass Display – Visualises the underground pipe/cable direction for fast and intuitive tracing.

2. High Sensitivity & Anti‑Interference – 2Hz ultra‑narrow bandwidth reception effectively rejects adjacent line and environmental noise.

3. Anti‑Mistracking Indication – Measures current phase (640Hz/1280Hz) and automatically warns when deviating from the target line.

4. Enhanced Passive Detection – Sweeps power and radio frequencies; displays up to three lines simultaneously for area surveys.

5. Multiple Signal Coupling Methods – Direct connection, clamp coupling, and induction – suitable for de‑energised/energised cables and metallic pipes.

6. Flexible Clamp Smart Identification – Compares both current magnitude and phase for reliable one‑cable identification.

7. Step Voltage Fault Location – With an A‑frame, precisely locates insulation breaks and sheath faults.

8. High‑Power Digital Amplifier – 15W adjustable output, automatic impedance matching, overvoltage/overcurrent protection.

9. IP65 Ingress Protection – Ruggedised for outdoor use; built‑in Li‑ion batteries support full‑day operation.

10. Optional GNSS & Data Logging – High‑precision single‑point or RTK (cm‑level) positioning, stores up to 256 records and transfers data via Bluetooth.
