enameled copper wire is a special insulating material (such as glass yarn, polyester glass fiber yarn and Kapton) lapped on the flat wire and round wire of bare wire/tube or enameled wire, and then impregnated with epoxy resin.
Using partially cured epoxy insulation after winding, the wires will adhere to each other when processed in a baking oven, providing a very strong finished product. This special insulated rectangular wire is used for generators and special motors that require excellent heat resistance and vibration resistance.
Single or double glass fiber insulated rectangular wire
Alkali-free glass filaments (Class E) have excellent physical properties and heat resistance, and are used in nuclear power generators and traction motors.
Polyester fiberglass insulated rectangular wire
Polyester glass yarn has excellent physical properties, excellent heat resistance and particularly excellent flexibility, so it is mainly used for stator coils of turbine generators.
Mica tape insulated rectangular copper wire
Mica-polyester compounds generally include mica paper on which a polyester film coating (PETP) is spread on the mica paper using epoxy resin. Mica paper is a paper composed of only small strips of mica without any additives or bonding materials (100% mica).
The same is true for the insulating layer of Rectangular Enameled Copper Wire.
