Wholesale Aluminum foil for transformer

What is aluminum foil for transformers

Aluminum foil for transformers refers to the aluminum foil used to make transformers. Transformer amûrek elektrîkê ye ku ji bo veguheztina voltaja an niha ya alternatîf tê bikar anîn, ku ji navikek hesinî û pêlekê pêk tê. Peldankek ji kulmek îzolekirî û ji hêlekê pêk tê, bi gelemperî têl an pelika sifir. Peldanka aluminiumê jî dikare wekî rêgezek pêlêdanê were bikar anîn.

Foila Aluminium ji bo transformator

Compared with copper foil, aluminum foil has the following advantages:

1. Lightweight: Aluminum has a lower density than copper and is lighter in weight, so a transformer made of aluminum foil is lighter than a transformer made of copper foil.
2. Rêwîtiya baş: Although the conductivity of aluminum is lower than that of copper, aluminum foil usually adopts a multi-layer structure, which increases its conductivity and can meet the needs of transformers for current.
3. Relatively low price: The price of aluminum is relatively low, so making transformers with aluminum foil can reduce manufacturing costs.

Types and parameters of aluminum foil alloys used in aluminum foil for transformers

Aluminum foil for transformers usually uses high-purity aluminum materials, such as electrolytic aluminum with a purity of more than 99.5%.
Herwisa, the alloy type of aluminum foil for transformers is usually 1000 doranî, wekî 1050, 1060, 1070, etc.

The following are some common aluminum foil parameters for transformers:

When selecting aluminum foil for transformers, in addition to the parameters of the aluminum foil, other factors need to be considered, such as the working conditions of the transformer, manufacturing process, nirx, etc.

Aluminum foil production process for transformers

• Raw material preparation: select high-purity electrolytic aluminum and cut it into the required size and shape.
• Hot rolling: The prepared aluminum material is hot-rolled and pressed into aluminum foil. The hot rolling temperature is usually between 300°C and 500°C.
• Cold-rolling: Cold-rolling the hot-rolled aluminum foil to make it more uniform in thickness and improve its surface quality and hardness. The cold rolling temperature is usually below 20°C.
• Quenching: Quenching the cold-rolled aluminum foil to make its hardness and strength meet the requirements.
• Trimming: Trim the quenched aluminum foil to make the edges smooth, burr-free, and meet the required width and length.
• Birrîn: Cut the trimmed aluminum foil according to the required length and width to make aluminum foil rolls of different specifications.
• Packaging: Aluminum foil rolls are packaged to keep their surface quality free from contamination and damage.

In the production process, it is also necessary to strictly control various parameters, wek germahî, speed, pressure, etc., to ensure that the quality of the aluminum foil meets the requirements. Vê bigire, various inspections and tests are required, such as chemical composition analysis, mechanical performance testing, surface quality inspection, etc., to ensure the quality and reliability of the product.
