Surface Material Structure Distribution Of Epoxy Resin Insulators

The outer insulation surface high voltage standoff insulators is formed by placing the mixed outer insulation material into the fixed-shape mold cavity high voltage epoxy and then vulcanizing it by heating and pressurizing. The surface material structure distribution epoxy resin insulator is different from the internal material structure distribution. If the surface layer high voltage epoxy resin is randomly distributed with silica reinforcing agent particles, due to the intermediate effect of the hydroxyl groups on the outer surface of the silica reinforcing agent and the anti-structuring agent hydroxyl silicone oil, a considerable thickness of siloxane molecules will exist on the surface of the silica reinforcing agent particles. The outer surface high voltage standoff has normal conformation of siloxane molecular active chain segments and a large number of free ends of siloxane molecules capped by organic groups.
