Transformer Aluminum Foil

Properties Strength Packaging and Delivery

Haomei equipped with advanced equipment and technology, is one of the leading aluminium foil for transformer windings manufacturers and suppliers in China.
In dry type transformers, aluminum winding have been commonly used. Aluminum strip can replace copper conductor in distribution transformers. Aluminum foil and sheet in appropriate strip widths and lengths have widely replaced wire in electrical transformers. Demand for aluminum strip/foil using for oil transformer is new and will be more.

Haomei produce high conductivity roll type electrolytic aluminum foil used to manufacture the winding of electrical transformer, distribution transformer and cast resin transformer.
1. The foil conductor is of high conductivity annealed quality.
2. Slitting is closely controlled to assure strip free of cracks, roughness, scaling, stretch marks.
3. Paper is interleaved between layers of each aluminum foil roll according to requirement of clients.
4. Each roll is tightly wound.
5. Coil is packed with eye to wall or eye to sky accordingly by sea worthy wooden pallet or box.
6. Foil is free of dents, surface defects, waviness, scale, or any other imperfections which would cause problems in either the winding, performance, or reliability of a quality manufactured dry or wet transformer.
7. The surface and edges of the foil is free of burrs and imperfections. The edges conform to a Round Edge.
8. The tranformer aluminum foil is shipped in tightly wound rolls with proper edge register.
