Resin thermal analysis

摘要

Thermomechanical Analysis Technology was used as a means of establishing a molding cycle for the manufacture of resin insulated bushings. The degree of cure of the resin system used in the molding process was found to be significantly different when heated vs unheated conductors were used. The glass transition temperature (Tg) was used to determine the degree of cure of the resin system and the coefficient of thermal expansion (??) of the resin was used as a guideline for choosing the appropriate molding cycle time best suited for economical production of the molded bushings.
