Abstract

See full text

An insulating polymer material composition is obtained by adequately adding a curing agent, a curing accelerator or the like to an epoxidized vegetable oil (such as an epoxidizable vegetable oil and fat which is an ester of glycerin and a fatty acid having a double bond portion therein), and heating and three-dimensionally crosslinking the resulting. As the curing agent, the curing accelerator or the like, those used for petroleum-derived polymer materials such as epoxy resins can be used. This polymer material composition is applied to, for example, insulating structures for high-voltage devices including a switching device such as a circuit breaker or disconnector in the casing.
