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.

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&#xb0; C. to 120&#xb0; 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.
