Aluminum foil tape for dry transformer

Aluminum foil tape for dry transformer 1060-O and 1070 o has the thickness of 0.2mm-4.0mm, width of 20mm-1450mm. It has smooth surface without scratches, the edges can be chamfered and smooth, which is better than national standards, the resistivity is 0.028 or less. Aluminum foil winding has a simple structure and good performance, which can reduce load loss, improve the technical and economic indicators of the dry transformer, and facilitate mechanized production. The aluminum foil for dry transformer fully complies with national standards and transformer production requirements. Resistivity and electrical conductivity have been recognized by users of production transformers, and have obtained SGS environmental certification and ISO certification. Haomei can produce aluminum foil strip suitable for epoxy dry-type transformers, epoxy cast dry-type transformers, etc.

When applied to dry type transformer, aluminum foil winding has the advantages of high space utilization, easy automatic winding, and high production efficiency, and the shaft is manufactured due to the structure. The lines are evenly distributed, the ampoules tend to be balanced, and the ability to resist sudden short circuits is enhanced. The dry-type transformer has the advantages of flame retardant, self-extinguishing, moisture-proof, high mechanical strength, small size, light weight, strong short-circuit capability, etc., and has been widely used.

The aluminum foil for transformer has large in-line capacitance, good shock resistance, and uniform distribution of the impact voltage gradient, which can effectively suppress potential fluctuations. Aluminum foil coils are lightweight, at the same resistance value, aluminum foil coils are only half the weight of copper foil coils. Use special electrical aluminum foil. Aluminum foil tape for dry transformer has been infiltrated into a rare earth metal, its conductivity remains unchanged, its mechanical strength is improved, and its surface is bright and difficult to oxidize. The dry-type transformer foil-wound conductor has the characteristics of large area, thin thickness, coexistence of excitation and induced current.
