Method for manufacturing winding wires

The invention provides a method for manufacturing winding wires. The method comprises the following steps: (1) covering a first layer of mica tapes horizontally; (2) covering a second layer of mica tapes horizontally; (3) covering a third layer of mica tapes horizontally; (4) carrying out winding covering; and (5) sintering, cooling and rolling. The winding wires manufactured by the method are smooth in surface, high in mechanical strength, good in manufacturability, strong in overload capacity and good in wet-heat resisting property; compared with glass fibers, the abrasive resistance of the winding wires is improved remarkably; the tiny gaps are generated when lap taping does not exist and the winding wire are easy to penetrate when vacuum pressure is utilized to soak, thus motor insulation realizes non-gap insulation; and the winding wires are applied to manufacturing stator coils of 6kV and 10kV motors.
