Electrical Underground Cable Outer Sheath Fault Location System
HS521 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.
