The Introduction of Glass Fiber Wound Enameled Rectangular Copper/Aluminum Wire

Glass fiber wound enameled rectangular wire is first enameled on high-quality copper (aluminum) wire, and then wrapped with glass fiber. According to customer needs, the required temperature resistance index of insulating paint is matched, and the baking treatment is carried out to make the glass fiber, insulating paint and conductor bonded into a whole. The temperature resistance classes of this product are 130, 155, 180, and 200, is widely used in generators, motors, motors and other electrical equipment windings.

The Product Features of Glass Fiber Wound Enameled Rectangular Copper/Aluminum Wire

Double insulation protection: The paint layer is the first layer of insulation, providing basic electrical insulation performance; the outer layer of glass fiber provides additional mechanical protection, wear resistance and high temperature resistance.
Excellent high temperature resistance: Glass fiber enameled flat wire has better high temperature resistance than ordinary enameled flat wire, and can withstand working temperature up to 200℃.
Good insulation performance: Both the paint layer and the glass fiber have good insulation performance, which can effectively prevent current leakage and short circuit.
Excellent mechanical strength: Glass fiber enameled flat wire has higher mechanical strength and wear resistance than ordinary enameled flat wire, and has a longer service life.
Good heat dissipation performance: The flat wire structure has a larger surface area than the round wire, which is conducive to heat dissipation, reducing the temperature rise of the conductor and improving the efficiency of electrical equipment.
Processing performance: Compared with ordinary glass fiber covered flat wire, the paint layer can improve the surface smoothness of the wire, which is conducive to the winding and processing of the coil.

The Application of Glass Fiber Wound Enameled Rectangular Copper/Aluminum Wire

◆ Motor: Widely used in various motor windings, such as high-voltage motors, traction motors, explosion-proof motors, special motors, etc. It is especially suitable for medium and high voltage AC motors, medium and large DC motors, medium and large wind turbines, etc. In high voltage motors, glass fiber enameled flat wire can provide higher insulation strength and anti-corona performance, ensuring the reliable operation of the motor.

◆ Transformer: Used in dry-type transformers, special transformers, etc. In dry-type transformers, glass fiber enameled flat wire can improve the heat resistance level and insulation performance of the transformer.

◆ Reactor: Used in various reactor coils.

◆ Electric welder: Used in electric welder transformers and cables.
