What is aluminum foil for transformers

Aluminum foil for transformers refers to the aluminum foil used to make transformers. Lub transformer yog ib qho khoom siv hluav taws xob siv los hloov hluav taws xob hloov pauv lossis tam sim no, muaj ib tug hlau core thiab winding. Lub winding muaj ib tug insulated kauj thiab ib tug conductor, feem ntau yog tooj liab hlau los yog ntawv ci. Aluminium ntawv tseem tuaj yeem siv los ua tus neeg xyuas pib winding.

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

  1. Lub teeb: 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. Zoo conductivity: 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%.
Ntxiv rau, the alloy type of aluminum foil for transformers is usually 1000 series, xws li 1050, 1060, 1070, lwm.

The following are some common aluminum foil parameters for transformers:

Thickness 0.1mm-0.5mm
Dav 20mm-500mm
Longitudinal tensile strength 60MPa-95MPa
Elongation 20%-30%
Kev coj ua 58%-62%IACS (International Electrotechnical Commission Standard)

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, tus nqi, lwm.

 

Aluminum foil production process for transformers

  • Raw material preparation: select high-purity electrolytic aluminum and cut it into the required size and shape.
  • Kub 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.
  • Txiav: Cut the trimmed aluminum foil according to the required length and width to make aluminum foil rolls of different specifications.
  • Ntim: 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, xws li kub, speed, pressure, lwm., to ensure that the quality of the aluminum foil meets the requirements. Tib lub sijhawm, various inspections and tests are required, such as chemical composition analysis, mechanical performance testing, surface quality inspection, lwm., to ensure the quality and reliability of the product.
