XHDD503 Underground Cable Fault Pinpointer
Description
The XHDD503, a portable underground cable fault detector
independently developed by our company, boasts acoustic-magnetic
synchronization detection technology that has matured over 50 years
and is highly regarded by industry users. This device is small in
size and light in weight, contained in a PVC protective casing for
convenient carrying after use. It is designed with a microammeter
display and adjustable knobs for electrical level, frequency, and
volume. The swing of the microammeter's pointer indicates the
magnetic field strength during flashover discharge at the fault
point. The electrical level knob can be turned to adjust the
reference value of magnetic field strength. During path detection,
the frequency can be adjusted to make the path signal clearer.
While locating faults, the frequency knob can be tuned to avoid
radio interference, and the volume can be adjusted to optimize the
sound signals for better audibility.

Product Features
1. Synchronously receive vibration waves, sound waves and
electromagnetic waves generated during discharge at the fault
point;
2. The acoustic and magnetic channels are designed separately and
powered separately, with stronger anti-interference ability;
3. Super magnification, detection depth is greater than 10 meters;
4. Ultra-low and low-power design, quiescent current is less than
10mA, and continuous operation is more than 20 hours;
5. Analog meter design, signal strength and trend are clear at a
glance;
6. Zero level can be adjusted arbitrarily, suitable for various
strong and weak scenes.
