• Cable route tracer

Usage: Cable path meter is a special instrument for accurately detecting the position and depth of buried cable in a certain range; path detection is completed by the path signal generator and path signal receiver (cable fault fixed point meter); The cooperation between the two uses the operation to accurately locate the cable path within the approximate cable embedding range.

Main composition

Path detection is mainly composed of path signal generator and receiver

Index parameter

4. High voltage generator

The device integrates a DC high-voltage source, a storage capacitor, a discharge ball device, an automatic discharge device, and a cable fault tester into a cart-type high-end experimental instrument. The device completely solves the problems of convenience, portability, safety and reliability of the traditional experimental device.

The instrument adopts high-precision, high-stability special high-voltage electronic components and high-frequency high-voltage technology to make the whole structure simple. In order to preserve the habit of using the transformer and the operating box to generate DC high voltage, the pulse generator adopts the humanized design operation mode and integrates the micro reliable circuit design. Safe and reliable, visually intuitive. Really impact the impact of not bad, but also has automatic timing impact, manual impact and pressure resistance. It is the most humanized trolley type DC impact high voltage equipment in China. It is the ideal product for our power cable fault detection.
