An optimization method of stochiometric value and filler content on cast cycloaliphatic epoxy used for high voltage insulation under tropical condition

The results of previous experiments show that the observed responses (moisture absorption v, dissipation factor tan δ and dielectric constant ε_r) are different for each specimen type. This is due to the variation of stochiometric value (SV) and filler content (FC). In this paper, we demonstrate the interaction between SV and FC factors by applying the statistical F test method. From the experimental results, we plot the curves of responses means, from which one can easily optimize the factor-level combination of SV and FC of the material Cast CEP. In conclusion, we suggest that the sample D4F3 is the most suitable high voltage insulation material for tropical regions
