摘要： A method for producing an electrical power device from subsequently manufactured parts by an additive manufacturing technique includes determining a target spatial distribution of a physical property of the electrical power device, the physical property being an electrical property and/or a mechanical property; forming a part of the electrical power device; selecting a physical property of a subsequent part of the electrical power device corresponding to the determined spatial distribution of the physical property such as to be different from a corresponding physical property of the part; and by means of the additive manufacturing technique, forming the subsequent part such that it is at least partially in contact with the part.
An electrical power device is obtainable by the method, and the electrical power device may be used as an AC or DC insulator in an HVAC or HVDC apparatus.-

摘要： An insulator for a gas-insulated device is provided, including an injection-molded insulator disc and a conductor, wherein the insulator disc includes a first circumferential surface, a second circumferential surface disposed radially outwards from the first circumferential surface, and a web portion connecting the first circumferential surface and the second circumferential surface, characterized in that the web portion includes a wave structure, the web portion having an inner wave profile at the first circumferential surface and an outer wave profile at the second circumferential surface, and the inner wave profile and the outer wave profile have a radius of curvature of 2 mm or more and 10,000 mm or less.
