• Adjustable voltage output ≥15kV
• Specialized for outer sleeve failure detection
• Precision locating capabilities
• Adjustable output voltage;
• High accuracy and stability;
•  Employs a high-sensitivity amplifier and galvanometer for balance indication;
• Zero-point protection;
• Automatic fault point detection, while retaining manual testing functionality;

The cable outer sheath fault tester is particularly suitable for:

1. High-resistance breakdown points in cables after installation, especially linear high-resistance breakdown points that are difficult to burn into low-resistance conditions, such as linear high-resistance breakdowns at cable joints.

2. Flashover-type breakdown points, where the constant current source can maintain the arc after breakdown, a stable current flows through the bridge, and the bridge has sufficient sensitivity.

3. Defects that have not yet broken down but have low resistance, such as insulation defects where a megohmmeter reveals a low cable resistance value, but the cable does not break down under operating voltage.
