Abstract: A method for producing an electrical power device having an insulator. The method includes, by means of additive manufacturing, applying a polymeric insulating material forming part of the device. The method also includes, in a subsequent consolidation step, subjecting the insulator to elevated temperature and pressure during a predetermined time period to consolidate the insulator.

Abstract: A wound electrical component includes a wound body comprising a plurality of wound layers of an electrically insulating material around a longitudinal axis of the body. The component also includes at least one printed electronics sensor consisting of printed circuits on a flexible substrate. Each sensor is interleaved between two of the wound layers of the wound body.

Abstract: The present disclosure relates to a wound electrical component comprising a wound body comprising a plurality of wound layers of a web of an electrically insulating material around a longitudinal axis of the body. The wound body comprises a plurality of electrically conducting layers of an electrically conducting material, each printed onto a respective separate area of the web in the wound body. An edge zone of at least one of the plurality of electrically conducting layers is connected to a printed high permittivity layer of a high permittivity material along said edge zone such that at least a part of the high permittivity layer extends, printed on the web, beyond the edge zone.
