TI 200 polyester-imine / polyamide-imide compound magnet wire

TI 200 polyester-imine / polyamide-imide compound magnet wire
Product Detailed
1)Material:CCC Chilean cathode copper 2)Size:a 0.6-7.5mm;b 2-30mm or OEM 3)Thermal Ievel:200C 4)Strong chemical resistance

Polyester-imine / polyamide-imide compound enamel copper flat wire is made by flat copper conductor (TBR, TBY1, TBY2), on which coating polyester-imine and polyamide-imide paint by the paint-srcaping tool or by the felt in 5-13 layers. Based on yielding strength of conduct, it can be divided into soft and semi-hard status, and is an ideal material to produce winding for dry transformer, oil-immersed transformer, generator, motor, reactor, and the other electric appliances. For special requirements of thickness of paint film, please contact us.


1. great heat resisting

2. very strong chemical resisting

3. good scraping resisting.
