AIW 220 Degree Polyamideimide Enameled Flat Copper Wire for Transformers
Application:
Industrial Motors and Generators (Especially High-Voltage, High-Power, High-Speed Motors) Large Motors: Used in ultra-high-power motors for rolling mills, ship propulsion, mining machinery, etc. High-efficiency and special-purpose motors: Such as variable frequency speed control motors, explosion-proof motors, and traction motors (used in electric vehicles and trains). Flat wire windings offer lower temperature rise and better heat dissipation. Generators: Hydro generators, steam turbine generators, etc., require the handling of enormous currents; the large cross-sectional area and compact structure of flat wire are ideal for these applications.
