Abstract

In this study, we evaluated the dependence of thickness and temperature in the breakdown strength of MDPE and effect of semiconductor. As the result, breakdown strength trend to decrease according to the increase of thickness and temperature. We obtained the result that the breakdown strength was a little lower in the structure of Semi/MDPE than Semi/MDPE/Semi, but breakdown strength of MDPE was greater both of all. The dependency of permittivity, tan ${\delta}$ and conductance on frequency and temperature were investigated. Both of the specimans showed the trend of decreased in permittivity as the temperature increased but increase as the frequency increased.
