XZH Portable cable fault location system XHGG502+XHDD503D+XHGX507+XHHV535-4TS
The set of equipment is used to detect the main insulation failure of power cables with voltage levels of 35KV and below accurately and quickly; calibrate the cable length; accurately detect the direction and depth of the cable buried.
★Cable fault pre-location: with the reflectometer XHGG502 based on the low-voltage impulse reflection method(TDR), and high-voltage decay(flashover) method (DECAY), multiple impulse(ARC)arc reflection method.
★cable path tracing, buried depth detection: XHGX507 cable pipe locator is an all-digital locator with clear display and reliable positioning. Graphical operation instructions and sound indication, making it the easiest-to-use pipe locator available today.
Powered by rechargeable battery, it can also display cable depth and current.
507 is a multifunctional cable fault tester, which can be used for cable fault location, identification, comprehensive testing of path and depth.
★Cable fault pinpoint location: XHDD503D uses acoustic-magnetic synchronization method, equipped with 2048 J surge generator and intelligent digital signal receiver.
The portable cable fault location system is configured with the removable ARC cable fault locator with ultra-high brightness, large LCD screen 12.1” display with touch control, making the process of fault pre-location quick, easy and efficient.
High voltage 2048 J surge generator XHHV535-4TS is accompanied by a surge levels switch which allows to achieve the maximum surge impulse energy at 8, 16 and 32 kV.
It has features operator safety assurance systems and provides a reliable and comprehensive technical solution for low- and medium-voltage cables faults.
