Abstract: The present invention relates to an electrical device comprising a gas-insulated transformer or reactor. The electrical device comprises a housing enclosing an interior space, at least a portion of which defining an insulation space containing a dielectric insulation fluid comprising an organofluorine compound, and an electrical component being arranged in the insulation space and being surrounded by the insulation fluid. The electrical component comprises at least one winding. The electrical device further comprises an electrical connector for bringing the apparatus from non-operational state to operational state by connecting at least one winding to a power grid. The device further comprises an auxiliary power source which is connectable to at least one winding when the apparatus is in the non-operational state.

Abstract: The present invention relates to an electrical apparatus having an insulating space which contains a dielectric insulation fluid comprising an organofluorine compound. At least one solid component of the apparatus that is directly exposed to the insulation fluid contains a basic body made of a first material and a protective layer made of a second material different from the first material, the protective layer being directly or indirectly applied on the basic body and having a thickness of at least 50 μm. The organofluorine compound is selected from the group consisting of: fluoroethers, fluoroketones, fluoroolefins, fluoronitriles, and mixtures thereof, and the first material comprises or consists of a material selected from the group consisting of: a polymeric material, a ceramic, a composite material, and mixtures or combinations thereof.
