Application Of Epoxy Resin Insulators In Medium Voltage Power Grids

In recent years, manufacturers of medium-voltage switchgear and power distribution equipment have increasingly favored high voltage standoff insulators. The power system has an increasing demand for insulation solutions that are compact, electrically stable, and mechanically reliable. As one of the core components, the material ratio and molding process of high voltage epoxy have been optimized multiple times to meet the insulation and support performance requirements of medium-voltage equipment.

epoxy resin insulator is commonly used in busbar supports, bushings, and internal mounting components of circuit breakers in medium-voltage switchgear. The composite structure formed after curing has both high dielectric strength and good mechanical stability, and can adapt to voltage and mechanical stress changes in the substation environment.

Manufacturers use automated pressure gel (APG) or casting processes to precisely control the epoxy resin and fillers, resulting in a dense, bubble-free high voltage epoxy resin surface that meets medium-voltage system standards in terms of mechanical strength and electrical insulation.
