Analysis Results Of Pre-insulated Bushing Aging Test

The experimental analysis results show that the corona aging of pre insulated sleeve is the result of the combined action of electrical and chemical reactions, rather than thermal effects.
The research team studied the aging problem of all-dielectric self-supporting pre insulated junction sleeve caused by corona, and proposed the aging mechanism of the interaction between the plasma generated by corona discharge and the surface of insulated joint sleeve, rather than thermal effects, combined with chemical analysis.
