Patent ID: 10931159

Abstract:
A producing method is for an electrical insulating structure covering an outer surface of a to-be-insulated object. The electrical insulating structure producing method comprises: a sheet production step of producing a main insulating sheet in which nanoparticles have been mixed; a cutting step in which the main insulating sheet is cut into main insulation tapes; a taping step of winding each of main insulation tapes on outside of the to-be-insulated object to produce a tape-wound to-be-insulated object in which a main insulated part is formed; a vacuum drawing step of vacuum drawing the tape-wound to-be-insulated object; an impregnation step of injecting a impregnating macromolecular polymer to impregnate the main insulated part in the tape-wound to-be-insulated object, and a solidifying step of raising the temperature of the insulated part to solidify the macromolecular polymer containing the nanoparticles.
