Underground Cable Pipe Locator | Pipeline Detection System | XHGX507B
The XHGX507B underground cable pipe locator has been used by thousands of users in the power cable testing field and enjoys a high reputation. It was developed with the latest concepts, especially for fast and accurate positioning of cable-to-ground insulation faults, energized path finding, depth positioning and cable identification.
This precision pipeline detection device combines a high-power multi-frequency transmitter with a fully digital receiver to trace buried cables and metal pipelines, measure depth and current, identify cables and locate pipeline ground insulation damage before excavation work begins.
Applications & Target Audience: Engineered for urban power distribution network cable maintenance crews, municipal street lighting management departments, commercial real estate and industrial park facility management teams, and highway bridge and tunnel electrical maintenance units that trace buried cables and metal pipelines, measure depth, identify cables and pinpoint ground insulation faults before excavation.
Product Features
Compass and direction display: visually displays the direction of the pipeline and the left and right directions;
Current direction measurement to eliminate interference from nearby lines (partial frequencies);
Depth and current measurement;
Fully digital high-precision sampling processing: stable and reliable, ultra-high sensitivity, extremely narrow receiving passband, strong anti-interference ability, fully suppressing the power frequency and harmonic interference of adjacent running cables and pipelines;
Running cable detection: high-performance transmitting calipers couple and output signals to the running cable to the greatest extent;
Cable/pipeline identification: the caliper (optional accessory) is convenient and easy to use, and clearly gives the identification result;
Ground fault finding: use the A-frame (optional) to locate the damaged point of the pipeline-to-ground insulation, with the arrow indicating the direction of the fault point;
Multiple detection frequencies: active detection and passive detection;
Multiple signal output modes of the transmitter: direct connection output, clamp coupling and induction;
Transmitter digital amplifier power output, automatic impedance matching and automatic protection;
Built-in large-capacity lithium-ion battery, automatic shutdown under voltage, automatic shutdown (receiver) without operation for a long time;
The casing is beautiful and sturdy, lightweight and portable.

Signal Transmission and Fault Location Methods
The XHGX507B offers flexible signal transmission methods and advanced detection functions to suit different on-site conditions. The transmitter injects a tracing signal into the target pipeline, and the receiver detects the electromagnetic field to trace the route, measure depth and pinpoint faults:
| Method |
Working Principle |
Typical Applications |
| Direct Connection Method |
Connects the transmitter output line directly to the metal pipeline and injects the signal, obtaining the maximum emission current. |
Water pipelines, gas pipelines, communication cables, power cables and cathodic protection test points |
| Caliper Coupling Method |
Couples the output signal onto the target cable with a high-performance transmitting caliper without disconnecting the line. |
Running (energized) cable detection and identification |
| Induction Method |
Transmits the signal without any electrical connection to the pipeline, using the built-in antenna for rapid surveys. |
Quick area exploration and pipelines without accessible access points |
| A-Frame Step Voltage Fault Location |
Uses the A-frame to measure the step voltage around the suspected area; the arrow indicates the direction of the ground insulation fault point. |
Pipeline insulation damage, unarmoured low-voltage cable ground faults and high-voltage cable sheath faults |
This instrument provides field engineers with a reliable, comprehensive solution for underground pipeline and cable management, helping avoid excavation damage and power outages through accurate route tracing, depth measurement and fault pinpointing.
You can select 50Hz or 60Hz power frequency to suit the local power grid.
