Electric inuslation

Films and tapes are essential components for electrical insulation in motors, transformers, and generators. They ensure electrical safety, thermal resistance, and mechanical stability across all voltage levels — from low to high voltage. The choice of materials depends on the specific requirements of the application and voltage class, with commonly used materials including polyester, polyimide, glass fiber, mica, non-woven and laminated composites.

Application Areas

Electric Motors: In low-voltage motors, films and tapes are used for coil insulation, slot liners, and winding bundling. For medium- and high-voltage motors, heat-resistant and partial discharge-resistant materials are applied to maintain insulation integrity under high thermal and electrical stress.
Transformers: In small (low-voltage) transformers, polyester films and paper tapes are used for layer and winding insulation. Medium- and high-voltage transformers require advanced insulating tapes made from mica, aramid paper, or glass fabric to provide high dielectric strength, thermal stability, and long-term durability.
Generators: Generators — especially those in high-voltage applications — rely on complex insulation systems. Mica tapes, glass-fiber-reinforced materials, and heat-resistant films ensure reliable electrical insulation under extreme thermal, mechanical, and electrical loads.
