Product overview: This testing machine is suitable for measuring the breakdown strength and withstand time of solid insulation materials such as plastics, films, resins, mica, ceramics, silicone, glass, insulation paints, etc. in air or liquid media at power frequency (48-62Hz) or corresponding DC voltage.
Scope of application: Suitable for continuous and uniform voltage boosting or step-by-step voltage boosting, apply AC/DC voltage to the sample until breakdown, measure the breakdown voltage value, and calculate the breakdown strength of the sample; Using a rapid voltage boost method, raise the voltage to the specified value and maintain it for a certain period of time until the sample does not break down. Set the specified value at this time as the withstand voltage value of the sample.
