The main transformer aluminum foil is 1 series and 3 line products. Because of its thermal conductivity, lightweight, formability, protection, resource saving, recycling, health safety and so on, it is widely used in electronic appliances and transformers. So what are the types of transformer aluminum foil?

 

Transformer aluminum foil is the most important material in manufacturing transformer winding, which directly affects the quality of transformer. First of all, let's find out what is transformer. The transformer is composed of four parts: winding, core, fuel tank and insulation sleeve. The main parts are winding and iron core, the winding is the circuit of the transformer, and the core is the magnetic circuit of the transformer. The two form the core of the transformer - the electromagnetic part.

 

Transformer aluminum foil and strip generally choose 1060, 1070 and 3003 aluminum strip, which belongs to the conventional series in the aluminum strip family. The 1 series and the 3 series aluminum plates belong to ordinary aluminum plates, and the thickness of aluminum foil used for transformers is generally between 0.02-0.055mm. Because the production process is relatively simple, relative to the mature technology, relative to the 5 and 6 line products has the advantage of price, but generally 5 and 6 series products belong to the high-end products, the production process is more complex, the quality of the product is better, the good extension rate and tensile strength can be satisfied. The processing requirements of the rules (punching, stretching) are high in formability.
