Product introduction

NALGT cable fault detector is to cater to industrial-grade power industry solutions and IT era of rapid development, the original cable fault tester limitations, using industrial embedded computer platform systems, network services, USB communication technology systematic, very greatly improve the instrument's functions and use value and convenient on-site environmental operations. Especially for the growing number of buried cable provides a unique data management software. The entire system meets national new power industry standard "DL/T849.1 ~ DL/T849.3-2004" special test e electrical e General technical conditions, the system is tested by the system host and the fault locator and meter three-part cable path for all kinds of power cable fault test, cable path, the depth of buried cables and cable testing archives to find the daily maintenance and management, as well as railways, airports and signal control cables, and streetlights accurate cable fault testing

Also called name 

Cable fault tester, high voltage cable fault tester, cable fault tester, pointing device, path analyzer, routing cable fault tester, cable fault Pursuit, portable cable fault location system, flash cable fault tester, cable fault sentinel, cable path analyzer
