Special insulation materials, such as Fiber-glass and Kapton, are lapped on bare conductors/tube or enameled wire for both rectangular and round wire and then, impregnated with epoxy.

With the partially cured epoxy - insulating material after winding, the wires are adhered to each other during processing in the baking oven to provide a very strong finished product. This special insulated rectangular wires are used for generators and special motors which require superior heat and vibration resistance.

Single or Double Fiber-glass Insulated Rectangular Wire
Fiber-glass has excellent physical characteristics, superior heat resistance and especially superior flexibility thus it is predominantly used for stator coil of turbine generator.

Mica Tape Insulated Rectangular Copper Wire
Mica-Polyester compounds generally comprise Mica paper on which a polyester film coat (PETP) is spread using an epoxy resin. Mica paper is a type of paper composed only of small strips of Mica with no admixture or bonding material (100% Mica).

Mica or PET + Mica Covered Rectangular Copper Wire is suitable for class ‘F’ (155°) insulation and it is applicable for manufacturing fields as below.

Application of Mica Covered Rectangular Conductors
• High & Low Voltage Motors
• Generator windings
• Dry Type Transformers

Kapton Insulated Rectangular Wire
Kapton (Polyimide film) insulated rectangular wire is designed for use in applications involving high operating thermal & voltage and such wire is used in aerospace and automotive applications, relays and traction motors, etc.
