Kapton® polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. It is a multi-layer heat fusible composite film that enables higher operational temperature (-269°C to 400°C) functionality and improved abrasion resistance. Together Besides these excellent physical, chemical and electrical properties Kapton® polyimide film provides important weight and space savings and is suitable for variety of electrical and electronic insulation applications such as formed coil insulation, motor slot liners, magnet wire insulation, transformers and capacitors.
Kapton® polyimide film Covered Conductors offers a wide range of applications in the construction of motors (specially in traction motors), aerospace equipments. It provides insulation with high electrical, thermal and mechanical properties over a temperature range of -269°C to +400°C. It provides higher Break Down Voltage (more than 8 KV BDV) as well as Temperature Class (220 °C) as compare with other insulated conductors. Insulating materials in traction motors have to withstand high temperatures and frequent changes of load and temperature. Standard materials applied for conductor insulation in Traction Motor application is polyimide film.
