Kapton Mica Tape


Kapton Mica Tape

Customers can avail from us Kapton Mica Tape in the required specifications. Being drastically thin, our Kapton Mica Tape spares sufficient room for the conductor, helping in size-reduction of the HT motor. The Kapton Mica Tape is further acclaimed for its high partial discharge resistance and increased thermal conductivity. Kapton Mica Tape is used for insulation of armature coil in class 200 traction motors.

 

Ruby Mica Uniform Kapton / Mica Tape is a lamination of calcined muscovite mica paper with a kapton polyimide Film. Mica Paper is further reinforced with aramid Fibroids, to aid an evenly spread, high thermal-grade silicone resin impregnation.

This mica tape being drastically thin spares more room for the conductor, thus helping in size-reduction of the HT motor. It almost sketches the perfect coil-insulation ; surpassing the best of all insulation attributes. They have a very high partical – discharge resistance along with increased thermal-conductivity, enabling the HT motor to run cooler for longer.

Application : This uniform mica tape is used for insulation of armature coil in class – 200 traction motors.
