Computer controlled voltage breakdown tester

Computer controlled voltage breakdown tester is mainly suitable for solid insulating materials such as wire bushings, resins and adhesives, impregnated fiber products, mica and its products, plastics, film composite products, ceramics and glass and other media under power frequency voltage or DC voltage breakdown strength and voltage resistance time test, the instrument is controlled by computer. It can collect and process all kinds of data in the test process quickly and accurately, and can access, display and print.
