Problems solved by technology

It is difficult to control the accuracy of the sample with a thickness of 1-2 mm, and the error of the sample produced is very large. Therefore, it is necessary to provide a device for measuring the breakdown field strength of the thermosetting resin to reduce the measured breakdown. The deviation between the field strength data and the real breakdown field strength data
