Apparatus for the generation, distribution and/or usage of electrical energy and component for such an apparatus

An apparatus for the generation, transmission, distribution and/or usage of electrical energy, the apparatus comprising:

• a housing enclosing an insulating space and an electrically conductive part arranged in the insulating space, the insulating space containing a dielectric insulation fluid comprising an organofluorine compound, at least one solid component of the apparatus being directly exposed to the insulation fluid, wherein the at least one solid component 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,
• wherein the organofluorine compound is selected from the group consisting of:
• fluoroethers, fluoroketones, fluoroolefins, fluoronitriles, and mixtures thereof, and
• wherein the first material is an insulating material and consists of a material selected from the group consisting of:
• a polymeric material, a ceramic, a composite material, and mixtures or combinations thereof;
• and wherein the second material comprises a polymeric material:
• selected from the group consisting of:
• epoxy resins, polyurethanes and mixtures thereof, or
• selected from the group consisting of:
• polyimide, polypropylene, polystyrene, polycarbonate, polymethyl methacrylate, polysulfone, polyetherimide, polyether ether ketone, aromatic hydrocarbon polymers, fluorinated polymers, silicone, as well as combinations thereof, when the protective layer has a thickness ranging from 1 mm to 10 mm, or
• selected from the group consisting of:
• polyimide, polypropylene, polystyrene, aromatic hydrocarbon polymers, fluorinated polymers, polyamide, an ethylene-monochlorotrifluoroethylene copolymer, as well as combinations thereof, when the protective layer has a thickness ranging from 60 μm to 100 μm.
