Composite electrical insulation materials based on mica papers
Mostly wide spread area of application of the composite materials based on mica papers is insulation of DC and AC traction motors and other electrical machines. Flexible mica based materials are applied as inter-phase and slot insulation. Molding materials based on mica papers are intended for manufacture of v-rings for traction motors commutators, and rigid sheets made of mica paper are applied for bar-to-bar insulation of traction motors commutators.
Rigid sheets for commutator insulation:
Used as insulation segment plates between copper plates in commutator of DC motors.

Moisture-resistant flexible mica laminates:
These laminates consist of mica paper combined with glass cloth and polymer films by epoxy-polyester or silicone resin. The materials are used slot, inter-phase and inter-layer insulation in insulation systems of electrical machines working in wet conditions. Can be processed with significant technological pressures on materials.
