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
