Abstract: A transformer for mounting on a mast of an air-insulated energy distribution network has a core which is protected against corrosion and environmental influences, while at the same time stable retention is provided. The transformer contains a winding block having a solid insulating body, in which at least one upper voltage winding and at least one lower voltage winding are arranged. The winding block delimits a completely peripherally closed central retention opening. Furthermore, a core unit is provided which has at least one magnetizable core and is inductively coupled to each lower voltage winding by each upper voltage winding. The core unit extends through the retention opening via at least one core leg and annularly extends around the winding block on the outside by a ring portion. Retention devices are provided for fastening the ring portion to the mast.

Abstract: A winding unit for connecting to a high-voltage grid or network includes a winding embedded in a solid insulating body and a first main connection terminal connected to a first winding end of the winding and disposed on a first support formed on the insulating body. A second main connection terminal is connected to a second winding end of the winding. The winding has partial windings and taps for adjusting the number of windings of the partial windings connected in series. Outgoing lines extending in the insulating body connect the taps to a tap connection terminal accessible from the outside. The tap connection terminals are formed on the support in order to encapsulate the higher voltage in a resin block over the entire periphery by using a shielding cage.

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: In a cost-effective and qualitatively better method for producing spacers for a winding unit of an electrical high-voltage device, at least two starting components are mixed together in a mixing chamber under vacuum to form a component mixture. The component mixture is transferred to an extrusion housing, likewise under vacuum, of an extruder in which a transport device is arranged and which is equipped with a mouthpiece delimiting an outlet opening. The extrudate exiting from the mouthpiece is cured by the addition of heat in a vacuum in order to obtain the spacers.

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.

Abstract: An electrical winding can be arranged concentrically around a magnet core. A novel transformer includes at least one magnet core and at least one electrical winding, wherein the electrical winding can be arranged concentrically around the magnet core. The electrical windings are connected fixedly to a fixing apparatus, wherein the fixing apparatus can be fixed in a radial plane. As a result, subsequent fixing of the electrical windings in relation to one another and in relation to the magnet core which is to be reinforced mechanically is dispensed with.
