Dry type transformer

Transformer aluminum strips are divided into different alloys, specifications, and tempers according to specific uses; the alloys are: 1050, 1060, 1070, 1350; the temper is: O (soft); the thickness is between 0.08-3.00mm. It is also called aluminum strip and foil for dry-type transformers. Aluminum strip and foil for dry-type transformers are made of high-quality pure aluminum. It has the characteristics of high conductivity, soft texture, smooth surface and no burrs. It is an ideal material for the production of dry-type transformers and the main raw material for manufacturing transformer windings. The electrical conductivity, burr curling, side bending, surface quality and other technical indicators of aluminum strips and foils are very demanding.

Dry-type transformers generally use 1060 aluminum strip and foil, which contain more than 99.6% aluminum and are also called pure aluminum strips foils. They have unparalleled conductive properties from other series of aluminum strips and are one of the most commonly used alloys. 1060 aluminum strip foil has good elongation and tensile strength, and can fully meet conventional processing requirements (stamping, stretching) and high formability; it has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity, but low strength, heat treatment cannot strengthen and the machinability is not good; it can be gas welded, hydrogen atom welded and contact welded, but not easy to braze; it is easy to withstand various pressure processing and stretching and bending.

The aluminum content of 1060-O/HO transformer aluminum strip is high, and the electrical conductivity and thermal conductivity of aluminum are only lower than those of conventional metals such as copper. The metal conductivity properties are in order: silver-copper-gold-aluminum-nickel-steel. Since the price of copper is much higher than aluminum, aluminum strip is currently the most commonly used material for transformers. The 1060 aluminum strip foil for transformers produced by Flait Aluminum has a smooth surface, no scratches, and the edges can be chamfered (rounded corners, rounded edges), without burrs, which is better than national standards. The resistivity is less than or equal to 0.028. A1060-O/1060-O transformer aluminum strip foil is mainly used in high and low voltage windings of dry-type transformers as conductive materials, large transformers, solar energy, and power industries.
