In this study, an epoxy insulation barrier for high voltage GIS was developed using epoxy and a filler with a Young's modulus of 11 GPa. The material was investigated using a simulation of the principal stress, displacement, and safety factors while optimizing the profile shape. The simulation showed that thelarger Young's modulus of the $Al_2O_3$ filler compared to the $SiO_2$ in the epoxy insulation can contribute to an increase in resistance to mechanical fracturing for theoptimized profile barrier in high voltage GIS. In addition, the safety factor was improved by 10%. It can be concluded that the mechanical fracturing properties of the insulation barrier can be enhanced by increasing the content of the elastic filler, $Al_2O_3$, for high voltage GIS applications.
