1600kV Lightning & Switching Impulse Generator

This equipment is a high-voltage impulse test system primarily used for standard lightning impulse full-wave, operating-wave, and truncated-wave impulse voltage tests on test specimens such as air gaps, suspension glass insulators, composite insulators, and bushings. The equipment features an 8-level H-type four-column tower structure (based on German HighVolt technology), with a rated voltage of ±1600 kV and a rated energy of 160 kJ. It is suitable for indoor use and complies with numerous national and international standards, including GB, DL, and IEC.
