Transformer winding aluminum tape | Haomei Aluminum

With the development of the economy, the amount of transformers has increased, and the demand for dry-type transformers has increased even more. Dry-type transformers have the following advantages over oil-type transformers, low cost, long life, good flame retardancy, high safety, low noise, low loss, small size, light weight, convenient installation and maintenance, and low frequency of inspection and maintenance, low local power efficiency, strong short-circuit resistance, strong lightning-impact resistance, strong overload capability and high reliability. The aluminum dry type transformer has good crack resistance, so transformer winding aluminum tape are widely used in dry type transformers.

Shearing is the most critical part of transformer winding aluminum strip production, mainly because the transformer aluminum tape has higher requirements for edge burrs. Since the transformer aluminum strap is used to wind the transformer, it is necessary to prevent the burr from piercing the insulating layer and avoid the burr tip discharge. The actual shape of the edge of the aluminum strip after slitting is not an ideal rectangle. Therefore, the production of aluminum strip for transformers must be edge treated to remove shear burrs and chamfered or rounded edges. The commonly raw materials for processing transformer winding is 1060 aluminum temper O(soft) with round edge and without burr. The thickness is 0.10-3.0 mm, the surface of the transformer winding aluminum tape is without pot and oil.
