Aluminum strip for dry-type transformer windings is mainly made of aluminum ingots after smelting and rolling and slitting. It uses high-quality pure aluminum as raw material. Common grades include 1060, 1050, 1050A, 1070, 1070A, 1350, etc. The state is usually O state (indicating soft state).

Advantages of aluminum strip for dry-type transformer windings:

Reduced cost: The price of aluminum is lower than that of copper. The use of aluminum strip significantly reduces the manufacturing cost of transformers, especially large equipment.

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

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

Flexible design: Aluminum strips can increase the cross-sectional area, and the conductivity is comparable to that of copper windings, making design and manufacturing more flexible.

Why choose transformer aluminum strips produced by MC Aluminum?

1. The surface of the aluminum strip should be smooth, flat, free of burrs, oil stains and dust.
2. Defects such as corrosion, oil spots, cracks, cracked edges, bubbles, holes, etc. are not allowed.
3. The surface coating of the aluminum strip (if any) should be uniform and firm, without peeling, cracking, etc.
