Why use aluminum strip for transformer windings?

Lightweight: Aluminum's density is about one-third that of copper, making aluminum strip significantly reduce the overall weight of transformers. This is particularly important for large transformers, lowering transportation and installation costs.

Good conductivity: Although aluminum's conductivity is slightly lower than copper's, the conductivity of aluminum strip still meets the needs of most transformers. With proper design, electrical performance similar to copper windings can be achieved.

Cost-effective: Aluminum is much cheaper than copper, making aluminum strip a more economical choice. For large-scale transformer production, using aluminum strip can significantly reduce manufacturing costs.

Easy to process: Aluminum has good ductility and formability, making it easy to process into thin strips and complex winding shapes. This makes aluminum strip suitable for various transformer designs.

Strong corrosion resistance: Aluminum's oxide layer provides excellent corrosion resistance, making aluminum strip suitable for use in humid or corrosive environments, extending the transformer's lifespan.

Why is Mastar's aluminum strip for transformers reliable?

Excellent production processes

Casting and Rolling: After heating the aluminum ingot, it is continuously cast and rolled to form thicker aluminum plates.

Hot Rolling: Hot rolling further reduces the thickness of the aluminum plate, improving mechanical properties and surface quality.

Cold Rolling: Cold rolling at room temperature further processes the material to achieve the desired thickness and dimensional accuracy.

Annealing: Annealing treatment eliminates internal stresses from cold rolling, enhancing the flexibility of the aluminum strip.

Finishing: Through edge trimming, straightening, and leveling, the aluminum strip's dimensional accuracy and surface flatness are ensured.

Surface Treatment: Coating or anodizing is applied as needed to enhance corrosion resistance.

Testing: The aluminum strip is rigorously tested for thickness, width, conductivity, and other properties to ensure quality meets standards.

Standard tolerance dimensions

Mastar's transformer aluminum strip products strictly adhere to dimensional tolerance requirements. For specific data, please refer to the tolerance table below.
