Product Description

Reliable LV Cable Fault Testing and Locator Equipment Sheath Fault Tester Set

The cable outer sheath fault tester is especially suitable for:

High-resistance breakdown points of cables after laying, particularly low-resistance linear high-resistance breakdown points such as cable middle joint failures
Flashover type breakdown points where constant current maintains the arc for stable bridge current
Low resistance defects that haven't broken down but show insulation weaknesses under operating voltage

Key Features

Based on MURRAY bridge principle for locating breakdown points and low insulation resistance defects
High-voltage constant current source with voltage regulator and R-type transformer (5000V no-load, 100mA short-circuit)
Special double-core high-voltage rubber cable with four-terminal resistance measurement for accuracy
Low-potential panel operation with insulating rod controls
Integrated 12806 display with automatic cable length calculation and fault distance measurement
Compact portable design combining high-voltage source and electric bridge (5.5kg)
No blind spots compared to wave reflection method, ideal for short cables and end-point breakdowns
