Transformer aluminum strip foil is the key raw material for dry and oil-immersed transformer windings. The main transformer aluminum strip foils are:1050 aluminum strip, 1060 aluminum strip, 1070 aluminum strip, 1350 aluminum strip, with temper O/HO, thickness 0.2-3.0mm. Transformer aluminum foil strip has high plasticity, corrosion resistance, electrical conductivity, and thermal conductivity, and is easy to withstand various pressure processing, extension, and bending, which can significantly improve the heat dissipation performance of transformers. No matter what size and needs you require for transformer aluminum strip foil, Flait Aluminum can meet it. Contact us now!
Transformer aluminum strip foil (aluminum strip foil for dry-type transformers) is made of high-quality pure aluminum. It has the characteristics of high conductivity, softness, good corrosion resistance and beautiful appearance. The surface is smooth and burr-free. It is the best choice for the production of dry-type transformers. The production of aluminum strips for transformers requires very high technical indicators such as conductivity, burr, side bending, and surface quality. The transformer aluminum strips and foils we produce meet or exceed national standards in many technical parameters. Aluminum strip foil for transformers can make dry-type transformers have the advantages of small size, light weight, good insulation performance, flame retardant, no pollution, small partial discharge, moisture resistance, smooth and reliable operation, low noise, low maintenance costs, etc. 1050/1060/1070/1350 transformer aluminum strips foils are widely used in high-rise buildings, underground, facilities, commercial centers, residential areas, hotels and coastal humid areas.
We strictly control the quality of the base material, control the alloy composition, optimize the rolling and annealing processes to achieve high electrical conductivity and mechanical properties of transformer aluminum strip foil, ensuring the stability of user use.
we have the advanced slitting processing equipment to ensure that burrs, ruffles and other quality problems are eliminated in the production process of transformer aluminum strips. The edge precision can be achieved 100% burr-free.
The resistivity of transformer aluminum strip foil is better than the national standard (≤0.028). After years of market running-in and close cooperation with our customer’s manufacturers, the transformer aluminum strip product has been further optimized.
