Solid Dielectric Breakdown Of Epoxy Resin Casing
Date: | Read: 14
The characteristic of epoxy bushing solid dielectric breakdown is that the breakdown field strength is closely related to the time of voltage action. Generally speaking, the breakdown of epoxy resin bushing with an action time t < 1s is electrical breakdown, the breakdown of epoxy resin cast bushing with an action time 1s≤t < several hours is thermal breakdown, and the breakdown of epoxy bushing manufacturer with a thermal breakdown time t≥ epoxy bushing for transformer in several hours is electrochemical breakdown.
