Analysis On The Causes Of Micro-convex Embedded State Of Filling Particles On The Surface Of Epoxy Resin Insulators

As for the state of the presence of aluminum hydroxide and a small amount of other filler particles with particularly large particle size on the surface of high voltage standoff insulators, due to factors such as the heating of the shaping high voltage epoxy mold, the pressurized vulcanization process and the fluidity of the colloidal silicone molecules, it is impossible for the outer edge material surface of the formed epoxy resin insulator to have particle protrusions, and it is most likely that the top of the particle will be parallel to the surface of the silicone rubber material.
