Aluminum strips for dry-type transformer windings are mainly made of aluminum ingots after smelting and rolling and slitting. They use high-quality pure aluminum as raw materials. Common grades include 1060, 1050, 1050A, 1070, 1070A, 1350, etc., and the state is usually O state (indicating soft state).

Advantages of aluminum strips for dry-type transformer windings:

Reduced cost: Aluminum prices are lower than copper, and the use of aluminum strips significantly reduces the cost of transformer manufacturing, especially large equipment.

Light weight: The density of aluminum is one-third of that of copper. Aluminum strip windings make transformers lighter, which is convenient for transportation and installation.

Good corrosion resistance: Aluminum oxide layer is formed on the surface of aluminum, which can reduce corrosion and extend service life.

Flexible design: Aluminum strip can increase the cross-sectional area, and its conductivity is comparable to that of copper winding, making it more flexible in design and manufacturing.

Specifications of aluminum strip for dry transformer:

Why choose transformer aluminum strip produced by MC Aluminum?

1. The surface of the aluminum strip should be smooth, flat, free of burrs, oil and dust.

2. No defects such as corrosion, oil spots, cracks, cracked edges, bubbles, holes, etc. are allowed.

3. The surface coating of the aluminum strip (if any) should be uniform and firm, without peeling, cracking, etc.
