XHHG521 is designed for cable sheath fault locating, high-voltage bridge cable fault tester is designed based on the principle of MURRAY bridge. It can be used to locate the breakdown points of various wire and cable after laying and the defect points with no breakdown but low insulation resistance. Of course, it can also be used to locate the defective points of various cables in the cable factory.

The high-resistance breakdown point of the cable after laying, especially the linear high-impedance breakdown point that is difficult to fire into low resistance, such as the linear high-resistance breakdown of the middle connector of the cable.

Flashover type breakdown point, after the breakdown, the constant current source can maintain the arc, there is a stable current through the bridge, the bridge has sufficient sensitivity.

Has not broken down, but the defect point of low resistance, such as the use of megohmmeter found low cable resistance, but the operating voltage does not break down the insulation defect point.

No-load voltage ≥7500V
Short circuit current ≥40mA
Positioning accuracy ± (0.2% · L ± 1) meters
Weight 11kg

Dimensions:
Working power supply: AC 220V+/-10% 50Hz
