Transformers Aluminum Foils

Aluminum foil is typically used in transformer windings to create a conductive path for electrical current and similarly used as enameled aluminum wire or enameled copper wire. The foil is wound into coils and placed within the transformer core, where it helps to regulate the flow of electricity.

One of the advantages of using aluminum foil in power transformers is its ability to withstand high temperatures. Aluminum foil can handle temperatures of up to 150 degrees Celsius without losing its electrical properties, making it ideal for use in transformers that generate a lot of heat.

The chemical composition of 1000 Series Aluminum Strip For transformer Winding is Al99.5%, which has high conductivity and low price, and has become an indispensable material for power transformers.
The transformer aluminum foil can be used not only for low voltage dry type transformers, but also for oil immersed transformers and high voltage transformers.
The electrical conductivity of the 1050 aluminium foil strip is up to 61.0-63.0%, which meets the national standard and can meet the requirements of transformers winding under different voltages and frequencies.

The main advantages:
The surface quality of the foil is high and the conductivity is good
After annealing, the elongation of the foil can reach 1% or more
The shape of the foil is good, the thickness tolerance is small, the width tolerance is ± 0.2mm, and the thickness control can be controlled below ± 5 microns
The annealed foil has good plasticity and can be stretched into a cylindrical shape without cracks during winding
