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.

Abstract: The present invention relates to a refill-container for replenishing and/or reconditioning an insulation fluid contained in an insulation space of an electrical apparatus. At least a portion of the interior of the refill-container defines a refill-fluid containment space, in which a refill-fluid comprising an organo-fluorine compound is contained. According to the invention, the refill-container further comprises an opening designed to be brought from a sealed state, in which the refill-fluid is hermetically contained in the refill-containment space, to an open state, in which the refill-fluid is allowed to flow through the opening out of the refill-containment space into the insulation space.
