Aluminum Strip for transformer

About Product

1.Aluminum and copper are the two conductors most commonly used in transformer windings. it is more economical to build the transformer windings with copper or with aluminum. In distribution transformers, aluminum foil windings have been successful. To select the right material, the designer has to take into consideration several factors such as weight, maximum size, transformer total cost, availability and cost of the material.

2.In a transformer that uses LV and HV aluminum windings, aluminum foil is a common component. HV windings are wound from aluminum foil that is combined with an insulation foil. LV windings are wound from single-aluminum sheets and combined with a cast-resin fiberglass fabric. Windings that use foil are exposed to less electrical stress than other windings that result in higher AC and impulse voltages.

3.Using our advanced equipment, we provide clients with premium aluminum foil for transformer windings. We supply in different series, including 1050, 1060, 1070, and 1350. Each of these are made with tempers HO (soft) and both side edges of the aluminum foil are round without burr, as well as manufactured and certified to ISO9001:2004 Quality Management Standards. With a monthly output of 800 tons, we can easily meet clients' needs. We also supply aluminum foil strips, aluminum bus bars, etc.

Explanation of Transformer

Explanation of Transformer

  • A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic field, which in turn induces a voltage in a second coil. Power can be transferred between the two coils through the magnetic field, without a metallic connection between the two circuits. Faraday's law of induction discovered in 1831 described this effect. Transformers are used to increase or decrease the alternating voltages in electric power applications.

How Transformers Work

  • Transformer
  • Basic Transformer Design It is important to remember that transformers do not generate electrical power; they transfer electrical power from one AC circuit to another using magnetic coupling. The core of the transformer is used to provide a controlled path for the magnetic flux generated in the transformer by the current flowing through the windings, which are also known as coils.
    There are four primary parts to the basic transformer. The parts include the Input Connection, the Output Connection, the Windings or Coils and the Core.

The advantage of aluminum windings

  • 1.Aluminium is used for transformer windings and for other wiring use.
  • 2.Aluminium generally takes more care in construction than copper, but when properly implemented no significant problems are caused by using Al rsther than Cu.
  • 3.Where winding volume is not an issue or where the higher winding resistance is acceptable, Aluminium can be substantially cheaper than Copper for the same application.
