The bare wire is cold-rolled, drawn, annealed and softened, and then painted on a mold and baked. With the development of motor technology, special enameled wires with high current and high voltage resistance are required in application fields such as wind turbines, traction motors, electric vehicle motors, and high-power transformers. The enamelled flat wire produced by the existing technology is difficult to meet the requirements in this respect, and the insulation thickness is often increased by wrapping, such as wrapping with composite mica tape to improve the withstand voltage, or increasing the inter-turn insulation during the winding process. Insulated way to achieve. Due to the increase in the thickness of the insulating layer, this implementation method is prone to cracking after bending, and the insulation capacity of the bending part is greatly reduced. In addition, it also brings problems such as increased winding volume, poor heat dissipation, and complicated processing technology, which brings product costs and Reliability issues.
