Structural Analysis Of High-performance Epoxy Resin Insulators For Aging Resistance

The thermosetting polymer system used in high voltage standoff insulators forms a robust structure through a three-dimensional cross-linked network. This network structure enables high voltage epoxy to maintain its dielectric properties in a high electric field environment and is not prone to sudden damage under various external stresses. The degree of cross-linking between resin molecular chains determines the reaction pathway of the material under thermal and electrical loads. The cross-linked network exhibits a small deformation tendency when subjected to temperature changes, which slows down the microscopic degradation process affecting the overall insulation performance of epoxy resin insulator.
