Abstract :
The reliability of the cable depends on production conditions and the insulation material. In this study, an EPR insulator specimen was fabricated for use in experiments. In addition, we selected the Arrhenius model, which is widely used for lifetime prediction, and the Weibull model for statistical analysis. The suitability between the two models was evaluated. The temperature change of material generates variation in the molecular weight and substance. For thermal analysis of EPR was doing an experiment of TGA, OIT, and the activation energy was obtained. The activation energy values was follows: TGA: 1.23[eV], OIT: 1.82[eV]. Because between temperature and life are related to the Arrhenius equation the Weibull distribution, was analyzed using the statistical program MINITAB.
