Aluminium strip for transformer

Aluminium strip for transformer is the key raw material for the manufacture of transformer windings, it is made by rolling and cutting of smelting aluminum ingot. As aluminum strip is one of the most popular products of Haomei Aluminum, it my turn to introduce the main product - transformer aluminum strip to you all. According to the use, the transformer aluminum strip can be divided into different grades, specifications and temper. The grades are: 1060,1050,1050A, 1060A,1070,1070A, 1350, the temper is O. O means of soft state, followed by the number that can show hard and soft, and the degree of annealing. The thickness is between 0.08-3.00 mm, known as: dry-type transformer aluminum strip.

AT ISSUE

There is a common misconception that a distribution transformer with copper windings is in some way more efficient, more reliable, or has higher short circuit strength when compared to a transformer with aluminum windings.

RECOMMENDATION

Improvements in technology regarding the use of aluminum in transformers have made aluminum-wound transformers the ideal choice for today’s applications.

RATIONALE

Operating Cost - Cooper Power Systems designs aluminum-wound transformers with windings of a larger cross-sectional area than would be used for a copper wound unit. This larger cross-sectional area translates to a lower current density, and an equivalent operating temperature. By reducing the current density in the windings, a low-loss design can be achieved with aluminum or copper windings.

Reliability - A transformer’s life is defined by the life of its insulation system. Because Cooper aluminum-wound and copper-wound units run at equivalent operating temperatures, the insulation systems age at the same rate for each design.

Lower Cost First - Whether low losses are the goal or not, aluminum windings are less expensive than copper windings. The following example shows two equivalent-loss designs, on with aluminum windings and one with copper windings.
