摘要：

This paper measured the dielectric properties of the kraft paper and three polymer materials before and after electro-thermal aging, the examined dielectric parameters are ac electric breakdown strength, dielectric constant and dissipation factor. Preliminary results show that under the same aging time, as the aging temperature rises, the dielectric strengths of kraft paper, PPS, PC and PET are not always lower; and under the same aging temperature, as the aging time rises, the dielectric strengths of kraft paper, PPS, PC and PET are not always lower; For kraft paper and polymer materials under different aging time and temperature, the dielectric constant and dissipation factor of kraft paper is much larger than the other three polymer materials under different temperatures and frequency.
