Kapton® (Brand Name of DuPont’s Polymide Film) Covered Wires 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 -196°C to +250°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.
Kapton provides exceptional overload protection and long motor life, even in the most demanding applications and environments.
