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.

Abstract: A composite insulator includes an insulating elongated core, a protective layer surrounding the elongated core, the protective layer including an outer surface with a shed profile and an adhesive primer layer disposed between the elongated core and the protective layer for adhering the protective layer to the elongated core, the adhesive primer layer including a coupling agent and particles of a low resistivity material. The method for producing a composite insulator includes preparing a first solution including a solvent, a coupling agent and particles of a low resistivity material, applying the first solution on at least a part of an envelope surface of an insulating elongated core and thus forming one or more first adhesive primer layers and applying a protective layer onto the first adhesive primer layer on the elongated core, wherein the protective layer includes an outer surface with a shed profile.

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.
