A METHOD OF MANUFACTURING AN ELECTRICAL COIL OR TRANSFORMER WINDING HAVING AN INSULATION DEVICE

摘要

An insulation device for electrical coils and transformer windings with a substantially rectangular winding cross section comprises an insulation layer (5, 6) made from a foil material which after being formed to a tubular shape corresponding to the outer dimension of the coil or winding (1, 2) is deformed to a cross-sectional profile (7a) corresponding to the cross section of the winding.
