Polyimide Insulated Magnet Wire with CCAR Quality

PI grade polyimide insulated high-temperature resistant voice coil winding   This insulated enameled wire is a specialized winding material for high-end speaker voice coils. It uses high-quality copper as the conductor and is equipped with a PI level insulation coating. It comes in two specifications, CCAR and ALR, and is suitable for the production and processing of various high-quality audio voice coils. The wire is made using polyimide insulation technology, with a dense and uniform surface paint film, strong adhesion, and resistance to paint peeling and cracking. It has excellent high temperature resistance and can withstand the high temperature heat generated by the high-frequency operation of the voice coil for a long time without aging or deformation. Copper conductors have superior conductivity, uniform and stable resistance, extremely low signal transmission loss, smooth current flow without buffering, and can accurately restore audio details, ensuring high pitched transparen…
