The digital burn-through bridge integrates burn-through and intelligent bridge. The rated voltage of the burn-through mode is 60kV, and the maximum arc current is 400mA, which can quickly burn high-resistance faults into low resistance. The maximum test current of the digital bridge is 750mA, which greatly improves the fault location accuracy. It is
particularly suitable for insulation fault pre-location of high-voltage, large-section, and long-length complex cable systems,such as insulation fault location of complex high-voltage cables with GIS terminals and cross-connections, and can quickly complete the location without removing the GIS switch and short-circuit cross-connection.

* Fully automatic test, one-button operation.
* Automatically diagnose the cable fault type and guide the next operation.
* Automatically detect whether the wiring is correct, and also has protective grounding detection.
* Automatic data storage function, which can easily view historical data.
* Digital power supply control mode, the output voltage and current are more stable.
* Wide range voltage input, and automatic discharge of the test product.
* Adopts a pull-rod chassis with casters, which is light and easy to carry.
* Compared with the wave reflection method, the bridge method has no blind spot, which is particularly suitable for judging short cables and fault points near the end.
* The output voltage is high and the current is large, which is particularly suitable for pre-locatinginsulation faults in high-voltage complex cable systems with long lengths and thick cross-sections.
