The correlation of chemical, electrical, and mechanical changes in Cavalite®T during thermal aging in an oil filled transformer environment

Abstract

The chemical changes in Cavalite®T during thermal aging in an oil filled environment have recently been determined. Cavalite®T is a new water based acrylic wire enamel designed for use in transformers. The chemical reactions proposed and the resultant changes in electrical and mechanical behavior can be expected for other acrylonitrile based acrylic polymers although the degree will vary.
