Aluminum foil conductor for transformer uses high-quality pure aluminum as raw material. It has the characteristics of high conductivity, soft quality, smooth surface and no burr. It is an ideal material for producing dry-type transformer and the key raw material for manufacturing transformer winding. It has high requirements for conductivity, burr curling, side bending and surface quality of aluminum strip and foil, The dry-type transformer has the advantages of small volume, light weight, good insulation performance, flame retardant, pollution-free, small partial discharge, moisture resistance, stable and reliable operation, low noise and low maintenance cost. It is widely used in high-rise buildings, underground facilities, commercial centers, residential areas, hotels and coastal humid areas.


 
Relying on the strong technology and market advantages of the domestic dry-type transformer raw material industry, signi aluminum has strictly controlled the melting and casting, rolling, heat treatment, finished product shearing and other process links from the aluminum strip melting and casting process. By controlling the alloy composition, optimizing the rolling and annealing process, the products have achieved high conductivity and mechanical properties. The products are exported to the United States and Latin America, Russia and other countries, and by the customer's praise.
 
Aluminum foil conductor for transformer generally uses 1060 Aluminum plate and strip, which contains more than 99.6% aluminum, also known as pure aluminum plate. It is a common series in aluminum plate and strip family. The advantages of this series of aluminum plate: the most commonly used series, the production process is relatively simple, the technology is relatively mature, and the price has great advantages compared with other high-grade alloy aluminum plates. With good elongation and tensile strength, it can fully meet the conventional processing requirements (stamping, stretching) and high formability. It is industrial pure aluminum with high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, which can not be strengthened by heat treatment and poor machinability; It can be gas welding, hydrogen atom welding and contact welding, not easy to braze; Easy to bear all kinds of pressure processing and drawing, bending.
