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.
