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.

Abstract: An insulation material for a DC electrical component. The insulation material includes a thermoset or thermoplastic matrix and a functional filler component. The functional filler component has a non-linear DC conductivity depending on an applied electrical field strength. At least in a temperature range of 0° C. to 120° C., the functional filler component has a bandgap in the range of 2 to 5 eV, and optionally in the range of 2 to 4 eV. Furthermore, a method for producing an insulation material, a use of an insulation material for a high voltage DC electrical component, a DC electrical component comprising the insulation material and the use of a DC electrical component comprising the insulation material in a high voltage DC gas insulated device are suggested.
