 Kapton Mica Tape

Ruby Mica® Uniform Kapton® I 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 partial-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.
