ASTM D149 Electrical Dielectric Strength Tester , Plastic Testing Equipment

Electrical Dielectric Strength Tester Plastic Testing Equipment

Scope of application:

It is mainly applicable to solid insulating materials, such as plastic, film, resin, mica, ceramics, silica gel, glass, insulating paint, etc., to measure the breakdown strength and voltage withstand time under power frequency (48~62Hz) or corresponding DC voltage in air or liquid medium. It is applicable to the mode of continuous and uniform voltage rise or step by step voltage rise. Apply AC/DC voltage to the sample until breakdown, measure the breakdown voltage value, and calculate the breakdown strength of the sample; The voltage shall be raised to the specified value by using the method of rapid voltage rise, and the sample shall not be broken down for a certain time. At this time, the specified value shall be the withstand voltage value of the sample.
