Abstract: A device or component thereof is provided for generation, transmission, distribution and/or use of electrical energy. In at least one insulation space formed within the device, there is a current-conducting component. The insulation space includes a dielectric insulation medium that surrounds the current-conducting component. This insulation medium includes a) at least one organofluorine compound selected from the group consisting of fluoroketones, fluoronitriles, and mixtures thereof and b) a carrier gas comprising at least one component selected from the group consisting of air, an air component, CO2, or a mixture of these components. The device includes at least one gas seal for sealing of the at least one insulation space from a further space. The gas seal includes butyl rubber as seal material.
