Abstract: A flange fitted around a round cylindrical condenser core of a bushing is described. The flange comprises an annular lower flange part arranged to fit around a radial shoulder of the condenser core such that a lower shoulder chamfer of the shoulder rests against lower flange chamfer of the lower flange part around the circumference of the condenser core; and an annular upper flange part fastened to the lower flange part and fits around the condenser core above an upper shoulder chamfer of the shoulder. An upper flange chamfer of the upper flange part is between an upper sealing element and a lower sealing element, forming an annular chamfer space is formed between the upper flange chamfer and the upper shoulder chamfer between the upper and lower sealing elements. The flange comprises an injection through hole for a filler material to be injected there through to fill the chamfer space.

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 socket, connectable to a plug-in device, wherein the plug-in device is a bushing and/or a plug-in cable termination, is described. The socket includes a current conduction path and a field control unit. The field control unit includes a layer arrangement with at least three conductive layers arranged around the current conduction path and separated by an insulating material
