HV Cable AC Resonant Tester

The 44kVA 44KV HV Cable AC Resonant Tester is a high-voltage testing device specially designed for power systems. It is mainly used for the AC withstand voltage tests of cross-linked cables, hydro-generators, main transformers, busbars, GIS (Gas Insulated Switchgear) and other electrical equipment. Operating on the principle of series resonance, the device generates high voltage and large current with minimal input power, making it an ideal choice for high-voltage testing departments at municipal, county and regional levels, as well as power installation and maintenance teams. Its multi-functional design can adapt to the testing requirements of cables of different lengths and various power equipment.
