INSULATION STRUCTURE MANUFACTURING METHOD, INSULATION STRUCTURE MANUFACTURING DEVICE, AND DYNAMO-ELECTRIC MACHINE

WIPO Patent Application WO/2020/144859

A1

This method for manufacturing an insulation structure that covers the outer surface of an object to be insulated comprises: a taping step (S13) in which a main insulation tape is wound on the outside of the object to be insulated; a nanoparticle adhesion step (S14) in which the object to be insulated on which the main insulation tape is wound is immersed in individual nanoparticles after the taping step (S13); an assessment step (S15) for assessing whether the winding of the main insulation tape has been performed a prescribed number of times; an evacuation step for evacuating the object to be insulated once an assessment has been made in the assessment step (S15) that the winding of the main insulation tape was performed the prescribed number of times; and, after the evacuation step, an impregnation step in which a high molecular weight polymer impregnant is introduced under pressure into the object to be insulated, whereby the object to be insulated is impregnated with said polymer impregnant.
