Cable Hipot Test System

Inquiry Form

The cable hipot test system includes frequency power, exciting transformer, reactors and voltage divider. Reactors are dry resin casting type, suitable for different cable tests. Variable-frequency resonance voltage raising device makes reactor and capacitor achieve resonance by adjusting frequency of power and getting high voltage and big current on tested objects.
The cable hipot test system is portable, special to test cables. Some pieces weight can be 60Kg easily to carry by two people and others 30Kg can be carried by one person.
