Product Introduction

       ND2806 Intelligent Cable Fault Tester is a highly practical device for locating cable faults. The complete set consists of a cable parameter high-voltage generator, a Power Cable Multiple Pulse Fault Ranging Instrument, a Power Cable Fault Pinpointing Instrument, and an Intelligent Cable Path Detector. It is used for testing open circuits, short circuits, grounding, low resistance, high resistance flashover, and high resistance leakage faults in power cables. It can perform wave velocity measurement, verify cable length, and establish cable archives for daily maintenance and management. It can also locate paths and test burial depth for non-operational cables.

       This instrument adopts multiple detection methods, utilizing advanced computer technology and microelectronics, and employs the world's leading multiple pulse method, providing clear and easily identifiable waveforms with high ranging accuracy.
