The Introduction of Glass Fiber Coated Polyimide Film Copper (Aluminum) Wire

Glass fiber coated polyimide film copper (aluminum) wire is a winding wire made by coating a polyimide film with adhesive material, wrapping it on a high-quality copper/aluminum conductor, and baking it to make the films and the conductors bonded together, then wrapped with a glass fiber wrapped composite insulation layer. The conductor shape can be divided into rectangular wire and round wire. Glass fiber coated polyimide film copper (aluminum) wire has voltage breakdown resistance and temperature resistance classes are 130, 155, 180, and 200.

Glass fiber coated polyimide film copper (aluminum) wire is widely used in windings of large and medium-sized high-voltage motors, special motors and electrical windings, dry-type transformers, reactors, wind turbines, and rail transit. It has excellent electrical properties and high mechanical properties and moisture and heat resistance.

The Product Features of Glass Fiber Coated Polyimide Film Copper (Aluminum) Wire

Excellent heat resistance: Polyimide film itself has excellent high temperature resistance, usually reaching a temperature resistance of 220℃ or higher. The addition of glass fiber and high temperature resistant insulating paint further enhances its heat resistance, enabling it to work stably and for a long time in high temperature environment.
Good electrical insulation performance: Polyimide film has excellent dielectric properties and breakdown voltage strength. The combination of glass fiber and insulating paint further improves its insulation performance and ensures the reliable operation of electrical equipment.
Excellent mechanical properties: The addition of glass fiber enhances the mechanical strength and wear resistance of the wire, enabling it to withstand certain mechanical stress and vibration.
Chemical corrosion resistance: Polyimide film has good chemical corrosion resistance and can resist corrosion from a variety of chemicals.
Thinner insulation thickness: Compared with traditional glass fiber covered wire, the use of polyimide film can achieve thinner insulation thickness, which is conducive to reducing the volume and weight of electrical equipment.

The Application of Glass Fiber Coated Polyimide Film Copper (Aluminum) Wire

◆ High temperature motor: Used for various motor windings that need to work in high temperature environments, such as motors in metallurgy, chemical industry, mining and other industries.
