Application Conditions Of Epoxy Resin Insulators In Ac Lines

The material of high voltage standoff insulators is derived from chemically cured synthetic resin, which is made by vacuum casting or molding process to form a dense insulator, which is beneficial for resisting the working requirements of high electric field strength.

The prerequisite for high voltage epoxy to be used in AC transmission lines under certain conditions is that it can exhibit a high dielectric steady state under the action of an electric field and meet the withstand voltage requirements in an AC environment. The epoxy resin insulator material possesses controllable dielectric strength properties and composite characteristics with reinforcing materials such as glass fiber, enabling high voltage epoxy resin to play a stable electrical isolation role in high-voltage scenarios.
