Abstract :
Silane epoxy resins are the name of new thermosetting polymeric insulation materials that have been developed, with the materials composition was obtained from the experimental research. Mathematical analysis to study the aging performance of the polymeric insulation materials for high voltage insulator in the tropical climate is the multiple regression model, it is derived from statistical science combined with statistics toolbox from matlab programme. For engineering proposed, it could be applied for silane epoxy resins, for some purpose, namely, 1) to prove aging mathematical model with the data from the natural and acceleration aging, 2) to determine optimal performance the sample in tropical climate, and the result is the sample coded RTV24, 3) to predict the service lifetime of samples, depend on critical electrical field (Vfo/L) and design criteria of insulator, 4) to determine the correlation between natural and acceleration aging test, in the form of acceleration factor, with turned out for ultraviolet radiation, temperature, and humidity are 77, 2, and 2 respectively. Using the results, natural aging test which takes long time and high cost is not necessary to be performed, since accelerated aging performance could predict the performance of natural aging test. The results of multiple regression model, it can be concluded that the silane treatment of the filler with the dose of 40 %, or specimen code of RTV24 gives optimal performance in the tropical climate.
