Abstract (en)
[origin: EP0167896A1] 1. A disc coil winding for transformers consisting fo one or more wound conductors forming alernately anti-clockwise and clockwise spirals and having radial cooling and insulating channel (46) which are arranged between the individual disc coils (41, 42), characterized in that at least the disc coils (41, 42) in the region of a high voltage input (45) are split into two parts which are identical in respect of winding technique, are arranged axially one above another, and carry the same voltage, and between which an additional insulating channel (47) is arranged which consequently is not subject of electrical loading in the axial direction in normal operation.
