Introduction
Product Overview
LB4-60A 2-in-1 Smart Bridge and Burnthrough Cable Fault Location
Introducing LB4-60A, a highly accurate high-voltage bridge designed to pre-locate cable faults. It is engineered to help find faults efficiently through smart technology, integrating intelligent diagnosis, bridge measurement, cross-section measurement and burnthrough functions in one compact system.
Accessories & Function
HV output cable
Used for the burn-through function.
Short connection cable
Short-circuits the cable end during distance testing.
Special ground wire
Grounds the equipment housing.
Test box
Supports regular calibration of the bridge fault location function.
Discharge rod
Used to discharge the cable.
Power cable
Supplies power to the device.
Discharge rod grounding wire
Grounding wire for the discharge rod.
Discharge rod hook
Hook attachment for the discharge rod.
Burn-through function
Illustration of the cable burn-through process.
Key Applications
Top Features
One Knob to Easy Operate
With its single rotary knob, all functions can be selected and controlled easily.
Easier Measurement
No need to analyse waveforms or perform complicated calculations. The system displays the distance between you and the fault directly.
Stronger Burning Function
Up to 60kV output voltage makes it easier to burn high-resistive faults into low-resistive faults in a short time.
Smarter Analyze
Intelligent diagnostic technology helps determine the fault type, recommends the test method and guides the operator into burnthrough or ranging mode.
