1) According to the thickness of the paint film, the voltage meter needs to reach the target voltage of 500/700/1000/1200V;
2) The applied voltage is AC voltage, nominal frequency 50Hz, sine wave waveform, the test transformer has a rated power of 500VA, waveform distortion under test conditions;
3) When the current of 5mA or greater than 5mA flows through the high voltage loop, the overcurrent device moves to check whether the sample fails. Test voltage drop <10%;
4) The voltage holding time of the voltage withstand test is 1 second, and the test interval between samples is 5 seconds;
5) 11 samples as a batch, after repeated aging after the voltage test, according to the different wire diameter, the voltage can be adjusted from 0-5000V;
6) Automatic sample conversion, breakdown alarm and indication;
7) Including 1 set of test support.
