    Abstract: A method for producing an electrical power device (100, 450) from subsequently manufactured parts by an additive manufacturing technique comprises 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 (50) of the electrical power device; selecting a physical property of a subsequent part (51) 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 (50); and by means of the additive manufacturing technique, forming the subsequent part (51) such that it is at least partially in contact with the part (50). An electrical power device (100) 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.

    IPC: H02G5/06

    Abstract: A supporting insulator (100) has an insulator body (10) and at least one conductor fitting (20) for applying a high voltage thereto. The conductor fitting (20) passes through the insulator in an axial direction (Z) whereby a contact area (C) between the insulator body (10) and the conductor fitting (20) is formed. The insulator body (10) comprises a notch (11A, 11B) abutting on the contact area (C); and the conductor fitting (20) comprises an adjacent notch (21A, 21B) abutting on the contact area (C). The notches (11A, 21A; 11B, 21B) form a pair of stress relief means for alleviating even those stresses stemming from a temperature difference.

    Abstract: An insulation material for a DC electrical component is suggested. The insulation material comprises 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℃ to 120℃, the functional filler component has a bandgap in the range of 2 to 5 eV, 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.
