Abstract

1. An induction coil, particularly an induction coil which is provided with dry insulation and has no iron core and comprises two or mor individual coils (1, 12, 13), which are concentrically arranged one in the other with intervening gaps and are electrically connected in parallel, wherein the numbers of turns of the individual coils (21, 22, 23) decrease from the inside to the outside, independently of their numbers of turns the windings of the individual coils have approximately the same axial height (H) and the individual coils consist of wound insulated conductors, characterized in that all individual coils (21, 22, 23) consist predominantly of identical conductor bundles (34), which are identical in structure and in conductor cross-section and consist of electrically insulated and twisted individual conductors (341), which have been pressed to have rectangular shapes (24a, 24b, 24c, 34a, 34b, 34c) having different dimensions in the direction of the axis of the coil.
