Introduction to enameled flat aluminum wire

 

Enameled flat aluminum wire is a flat electromagnetic wire made of aluminum with an outer layer coated with insulating varnish. This wire has excellent insulation properties and mechanical strength and is widely used in windings of electrical equipment such as transformers and motors. Compared with traditional copper enameled wire, enameled aluminum wire is easier to wind, lighter in weight, and has good cost-effectiveness.

 

1. Features of enameled flat aluminum wire

 

1. Excellent insulation performance: The surface is coated with a strong oxide layer and insulating varnish, which can effectively prevent electrical short circuits.

 

2. Light weight: Compared with copper wire, aluminum wire has a low density and is suitable for applications with weight requirements.

 

3. High mechanical strength: Made of special molds, it has a rounded rectangular cross-section and enhanced tensile strength.

 

4. Easy to wind: Aluminum is more flexible and suitable for precision winding processes.

 

5. Corrosion resistance: The oxide layer can effectively prevent the external environment from corroding the conductor and increase its service life.

 

2. Specifications

 

Enameled flat aluminum wire complies with multiple international and national standards, including but not limited to:

- GB/T 5584.3—2009

- GB/T 7095.6-1995

- IEC 60317-16

- NEMA MW 35

- NEMA MW 77-C

- JIS-C3202

- MW83-C

 

3. Processing Technology

 

Enameled flattening: The aluminum wire is pressed into a flat shape by special equipment.

.Cold drawing: Further adjust the size and improve the surface quality and mechanical properties.

Softening: Heat treatment is performed to make the aluminum wire reach the appropriate flexibility.

Painting: The surface is coated with insulating paint to improve heat resistance and insulation performance.

4. Application Fields

 

Enameled flat aluminum wire is widely used in the windings of multiple electrical equipment, including:

- Transformer: Used for high-efficiency power transformer windings.
