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 surge arrester and a method for manufacturing the surge arrester are disclosed. The surge arrester includes a preassembled active part extending in a longitudinal direction, and a separately produced flexible housing defining a bore in the longitudinal direction and having an opening at an end surface of the flexible housing. The flexible housing is arranged surrounding the active part via the bore and in contact with the active part. The contact causes a deformation of the flexible housing in a circumferential direction, and the deformation generates a pressure applied on the active part along a radial direction.

Abstract: A method for forming an article of manufacture using additive manufacturing, includes: a processor executing program instructions to: (a) rotate an object continuously about a horizontal axis using a first rotational stage, wherein the object is partially submerged in a bath of energy curable liquid formulation during the rotation; (b) control a rate of rotation of the object to achieve a desired radial thickness of a sub layer of uncured liquid formulation at a desired rotational location on the object; (c) direct an energy source to provide an energy dose onto the object at a desired rotational location, wherein the energy dose is configured to cure and solidify the sub layer; and repeat (a), (b) and (c) until a desired radial thickness of a cured liquid formulation layer is a achieved.
