Abstract
Gas insulated electrical equipment includes: a metal enclosure having an insulating gas introduced therein; a conductor that is accommodated inside the metal enclosure and to which voltage is applied; and an insulating and supporting member insulating and supporting the conductor relative to the metal enclosure. The conductor is circumferentially covered with a dielectric film, and furthermore, a nonlinear resistance film provided on the dielectric film and having a nonlinear volume resistivity decreasing when the nonlinear resistance film is acted on by an electric field higher than a critical value.
