Aluminum Foil

Product-Aluminum Foil

Transformer aluminum foil, commonly referred to as transformer aluminum strip or transformer aluminum winding, is a crucial component in transformer manufacturing. It is typically made from high-purity aluminum and is used for winding transformer coils due to its excellent electrical conductivity and thermal conductivity properties. The aluminum foil is carefully wound around the transformer’s core to create the primary and secondary windings, facilitating the efficient transfer of electrical energy between them. Its high conductivity allows for minimal energy loss during power transmission, while its thermal conductivity helps dissipate heat generated during operation, ensuring the transformer operates efficiently and reliably. Transformer aluminum foil is available in various thicknesses and widths to suit different transformer designs and specifications, offering flexibility and versatility in transformer manufacturing processes.

Aluminum Foil is widely used in oil-immersed transformers, dry transformers, electric reactors, and other similar electrical instruments.
