Electric band winding has electrical insulation between successive windings provided with greater insulation breakdown resistance adjacent longitudinal edges of winding conductor band

摘要

The electric band winding (1) has at least 2 windings (2,3) formed by an electrical conductor band, which are insulated from one another via an intermediate electrical insulation (5), which has a greater insulation breakdown resistance in the vicinity of the longitudinal edges (6,7,8,9) of the electrical conductor band. The electrical insulation may be provided by a first insulation material (M1) adjacent the longitudinal edges of the electrical conductor band and a second insulation material (M2) between these edges.
