Aluminum windings take up a large amount of the space in air-cooled transformers. Therefore, for economical and low-cost production, we use transformer aluminum strips.
Transformers with rated powers up to 4 MVA that are dry-type or oil-immersed use aluminum windings.
The dry type and oil-immersed transformer windings are the primary applications for aluminum foil strips for transformers, also known as aluminum transformer strips foils.
Transformer aluminum foil strips come in thicknesses ranging from 0.2 to 3.0 mm and widths ranging from 30 to 1600 mm.
Paper, kraft paper, polyester film, or glass cloth are examples of insulating materials over which the coils are wound.
Aluminum foil strips for transformers are vital components in the transformer manufacturing process because of their high conductivity, excellent resistance to corrosion, and attractive appearance.
GNEE Aluminum is guaranteed to have the aluminum coil strips in any size you require with a tight tolerance!
