Aluminum foil can be used as an electrical insulator in transformers. It has low resistance and good heat dissipation properties, which makes it an ideal material for this purpose.
Aluminum transformer
The transformer is composed of four parts: winding, iron core, fuel tank and insulating sleeve. Its main parts are winding and iron core (body). The winding is the circuit of the transformer, and the iron core is the magnetic circuit of the transformer.
The two constitute the core of the transformer - the electromagnetic part . The aluminum foil for transformer winding is the main material for making transformer windings, which directly affects the quality of the transformer. Transformer aluminum foil generally uses 3003, 1060, 1070 and 1050 aluminum.
