For example, the electrical winding may include multiple windings of a winding conductor wound to form a coil. The coil has been embedded into a solid insulation body. In some embodiments, a coating of an electrically conductive material, comprising a resin matrix and microscale filler, has been applied to at least one surface of the insulation body.

Abstract: The present disclosure relates to electrical windings for a dry transformer which allows construction of a compact dry transformer even in relatively high voltage classes. For this purpose, the electrical winding has multiple windings of a winding conductor wound to form a coil. The coil has been embedded into a solid insulation body. In some embodiments, a coating of an electrically conductive material, comprising a resin matrix with at least 0.05% by weight of nanoscale filler, has been applied to at least one surface of the insulation body.

Abstract: A winding configuration for a transformer or an inductor has a winding formed by a winding conductor, a solid insulation surrounding the winding and a connecting unit embedded in the solid insulation. The aim is to obtain a winding configuration which provides the required dielectric strength even at higher operating voltages. In order to achieve this goal, the connecting unit is a plug lead-through and is configured to allow the connection of a cable connector.

Abstract: A winding assembly has a plurality of winding sections that are arranged one above the other in an axial direction and that are electrically connected together to form a series circuit. Retaining devices retaining the winding sections at a distance from one another. The winding assembly which has a high dielectric strength and the disc windings are connected together with a small spacing. The retaining devices have at least one retaining element which extends into at least two mutually adjacent winding sections and the retaining element is rigidly connected to the winding sections into which the retaining element extends.

Abstract: A winding arrangement has a number of winding sections arranged one above the other in the axial direction. The winding sections are arranged at a distance from each other and are electrically interconnected such that they form a series connection. The winding arrangement allows vertical potting with a winding insulation. At least one foot element is provided, which is connected to a winding section and is configured to carry the entire winding arrangement.

Abstract: A winding arrangement has a foot support for upright potting. The winding arrangement has a number of winding sections that are arranged on top of one another in the vertical direction and at a spacing distance from one another. The winding sections are electrically connected to form a series circuit. Each winding section has winding layers which are wound one on top of the other. The winding layers are insulated from one another and have an electrical conductor. Slipping of the winding sections is avoided by fixedly connecting the winding layers to one another by a layer connecting devices.

Abstract: A winding arrangement includes a plurality of winding sections being mutually spaced apart in axial direction and electrically connected to one another forming a series circuit. Each winding section includes a conductor wound from an inner end to an outer end of the winding section and thus enlarges the winding section in radial direction. At least one winding section is electrically connected at its outer end to the inner end of the following winding section in axial direction, which can be cost effectively produced. The winding sections thereof are disposed at a comparatively small mutual separation. At least one following winding section in axial direction forms a stepped region in which the inner end thereof is disposed in the radial direction at the height of the outer end of the winding section to which it is electrically connected. A transformer and a coil having the winding arrangement are also provided.
