aluminum foil for transformer winding

Jan 02, 2023

Aluminum foil for transformer winding has the characteristics of high conductivity, soft quality, smooth surface and no burr, which is the ideal materials for dry-type transformer production. They are the key raw materials for transformer winding. They require a lot of technical indexes such as conductivity of aluminum foil for transformer winding, burr crimping, side bending and surface quality. They can make dry-type transformer in application. Transformers have the advantages of small size, light weight, good insulation, flame retardant, pollution-free, small partial discharge, moisture resistance, stable and reliable operation, low noise and low maintenance cost.

Relying on the strong technology and market advantages of domestic dry-type transformer raw material industry, Aluminum has strictly controlled the process of casting, rolling, heat treatment and finished product shearing from the melting and casting process of aluminium strip. By controlling alloy composition, optimizing rolling and annealing process, the products have achieved higher electrical conductivity and mechanical properties. The products are exported to the United States, Latin America and Russia. And other countries, and by the customer's unanimous praise.

Aluminum foil for transformer winding is usually made of 1060 aluminium strip. The aluminium content of 1060 aluminium strip reaches 99.6%, which is also called pure aluminium strip. It belongs to a common series in the family of aluminium strip. With good elongation and tensile strength, it can fully meet the requirements of conventional processing (stamping, drawing) with high formability. For industrial pure aluminium, it has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but its strength is low, heat treatment can not strengthen the machinability is not good; it can be gas welding, hydrogen atom welding and contact welding, not easy to braze; it is easy to withstand all kinds of pressure processing and extension, bending.
