1. form the method for self-regeneration electric insulation coating layer on the length of a magnetic wire that in electric equipment, uses, described magnetic wire is shaped and places on the supporting member of described equipment, and have be positioned to relative along another surface of the described length of magnetic wire or with the surperficial facing surfaces of another magnetic wire, described method comprises:

  • Make these surface-coated one deck electrical insulating materials of each magnetic wire, described material consists of the coextensive continuous electric insulating barrier in described surface that forms with described magnetic wire, described insulating material also comprises the utricule of electrical insulator precursor material, described utricule is less than the thickness of described insulating barrier, and have a certain amount of so that in crackle can be formed on the part of insulating barrier subsequently, locate to discharge the electrical insulator precursor material;

    And thereafterBe shaped described magnetic wire to be placed in the described electric equipment, described certain position that is formed in described insulating barrier causes mechanical stress, described utricule consists of to be broken at the stress position place and discharges precursor material, at described stress position place, crackle forms in insulating barrier, thereby reduces the resistance of insulating barrier in these positions.
