Abstract (en)
[origin: WO9512887A1] A winding device (1) is used to wind a closed ring core for high-power transformers and chokes with electrical conductors (8). To this end, the winding device has a guide (3) surrounding the ring-core shank (5) to be wound and a plurality of unwindable winding rollers (4, 4a) movable along said guide through the ring core. The preferably strip winding material, i.e. conductors (8) or intermediate insulation (26), which is wound on the ring core shank (5) from the winding roller (4) during its rotation, is on said winding roller (4, 4a). It is thus possible to wind electrical conductors and insulation in layers in one cycle. The guide (3) is in the form of openable and closable tongs with a separating point (7). The low and upper voltage windings can thereby be applied to the ring core (2) in partial windings.
