Epoxy Resin Insulators Do Not Have The Problem Of Aging Oil.

high voltage standoff insulators As a solid insulating component, epoxy resin's material properties differ significantly from traditional oil-immersed insulation systems. Epoxy resin is described as a thermosetting polymer; its three-dimensional cross-linked structure determines that its aging mechanism under long-term operating conditions is primarily influenced by thermo-oxidative aging, damp heat, and environmental stress, rather than chemical degradation caused by oil deterioration. This type of material does not involve the swelling or deterioration issues at the oil-solid interface found in oil-immersed insulation media.

The network structure of high voltage epoxy forms stable molecular chain crosslinks during the curing stage, which makes the decomposition process of the material itself unrelated to the contact with oil. Thermo-oxidative aging is mainly manifested in phenomena such as molecular chain breakage and oxidation product formation. epoxy resin insulator will show changes in surface structure under extreme thermal conditions, but these changes are not caused by oil migration or oil aging.
