XHDD503C
The cable fault location instrument uses the acoustic and magnetic synchronization method to determine the power cable fault point. The electronic flashover is generated by the impact discharge generator, picked up and amplified by the corresponding probe, and the precise location of the fault point is determined by auditory and visual judgment. It is a device that completes the precise positioning of the cable fault point within the rough measurement range and collects the acoustic and magnetic time difference. It integrates positioning technology, path-assisted testing and other technologies, providing multiple test modes and rich and diverse prompt information to efficiently and accurately complete cable fault location.
This cable fault pinpointer is suitable for low-resistance, short-circuit, open-circuit and disconnection faults of power cables, high-frequency coaxial cables, street light cables, and buried wires made of various materials with different cross-sections and media, as well as high-resistance leakage and high-resistance flashover.

XHGX507C
XHGX507C is a path detection instrument with strong comprehensive performance.
It has multiple functions such as pipeline path detection, cable identification, fault finding, etc. The instrument consists of a transmitter, a transmitting current clamp,
a receiver, a receiving flexible current clamp, a connecting test line, and an A-frame (optional).
The cable path tester can be used for path detection, pipeline census and depth measurement of metal pipelines and underground cables without excavation. The instrument uses a variety of filtering technologies, has anti-interference capabilities, can accurately locate and measure depth, and is suitable for the detection and patrol of various underground metal pipelines, pipeline management and maintenance, municipal planning and construction, and pipeline detection in power supply and other departments. It is one of the necessary instruments for pipeline maintenance units. This function is achieved by the cooperation of signal transmitters, receivers, signal transmitting clamps and connecting test lines.
Features
1. Multiple detection modes: classic positioning mode, wire cruise mode, signal distortion measurement mode;
2. Classic positioning mode: compass, direction and signal amplitude display, intuitive display of the left and right directions of the pipeline.
