TRANSFORMER ALUMINUM STRIP

Product Name: Transfomer Aluminum Strip for Transformer Winding 1060-O

we always use Transformer Aluminum strip to make dry-type power transformers. People also use it as secondary induction coils of maglev constant-current transformers.
People use Transformer Aluminum Strip to reduce weight. and allow the induction coil to float above the electromagnetic suspension. it also has A closely related usage. we use aluminum winding for the protection of transformer overloaded reactor physical devices.
The economy of the application of aluminum strip in transformer windings is determined. by the price ratio of aluminum and copper windings. Considering the manufacturing cost. if the manufacturing cost of the reduced copper winding power rating is still higher. than that of the aluminum winding transformer of the same rated power. it is more economical to use transformer aluminum strip. The most economical current density of copper windings is 2.5-3.5A/mm2. and the most economical current density of aluminum windings is 1.5A/mm2.

Metal prices vary from place to place, but there are certain rules to follow.

For transformers smaller than 2.5MV.A, it is more economical to use transformer aluminum strip.

and it is important to be lower, because 90% of transformers in the world are smaller than this value.

For transformers larger than 25MV.A, aluminum strip is not suitable due to the size of aluminum windings.
In an air-cooled transformer, the aluminum winding take up most of the transformer space. so we use transformer aluminum strip to have economical and less expensive to produce.
In terms of load and size, the best transformer aluminum strip winding material is semi-hard aluminum.
Recently, dry-type or oil-immersed transformers with rated power up to 4MV.A have adopted aluminum windings.

aluminum strips has many advantages. We have good heat dissipation in the transformer aluminum strip winding. Moreover we have high resistance to short-circuit current. And also we could improved voltage distribution caused by impulse voltage, and easy automation of the production of this aluminum winding.
