Surface Mechanical Strength Of Epoxy Resin Insulators

The high mechanical strength of the high voltage standoff insulators surface layer makes the high voltage epoxy surface less susceptible to cracks. The electrical strength of the epoxy resin insulator generally remains constant throughout operation, and the high voltage epoxy resin aging process is much slower than porcelain. Therefore, the high voltage standoff is primarily scrapped due to self-destruction, which occurs within the first year of operation.
