Polyester/Polyimide Covered Winding Wire
The DetailsHeg
Polyimide film is coated with a high temperature resistant binder and coated with a polyimide film strip. After heating, the thin film band becomes a continuous insulating layer. The winding wire has high temperature, low temperature and radiation resistance, the sealing, electrical and wear resistance. It is applied to steel rolling motor high temperature operation, traction motor, deep well pump motor and dry Transformer coil.
For Aromatic polyimide tape-covered aluminum magnet wire, after the aluminum magnet wire is taped with a tape that is 1.5 mm thick with 1.0 mm of this thickness being polyimide film and the remaining 0.5 mm being fluoroplastic, it is heated and heat-sealed.
