Abstract
A method is disclosed for production of a winding block for a coil of a transformer, having at least one winding composed of electrically conductive wire or strip material with a plurality of turns. An insulating layer is composed of electrically insulating fiber material with a specific number of windings of the insulating fiber material. The turns composed of electrical conductive material are fitted independently of the turns of the insulating material and, after a predetermined number of turns of electrically conductive material have been fitted, a smaller number of turns of electrically insulating material are fitted over the same section onto these turns of electrically conductive material, such that electrically insulating material which remains before reaching a number of turns of electrically conductive material is used as edge insulation.
