Aluminum for electrical transformers uses high-purity aluminum with an aluminum content of more than 99.60%. It is an aluminum deep-processing product formed by slitting and processing aluminum coils. The main processing equipment for dry-type transformer aluminum strip is a slitting unit, which can cut them into required length and width according to needs. This helps to reduce processing procedures (no cutting), and save raw material costs.
1050 O aluminum strip
1050 O aluminum strip is the most commonly used material in transformers. The reason why it can be widely used in transformers is related to its excellent performance. The 1050 flat aluminum strip has high electrical and thermal conductivity. In the actual application process of transformers, 1050 O aluminum strip is usually used as supporting material to form transformer winding, which can reduce the loss of transformer and improve the performance of transformer.
1050 aluminum strip is generally between 0.1mm and 1mm. With single-layer or double-layer structure, it can effectively reduce the leakage magnetic field of the coil and improve its insulation performance.
1060 aluminum strip
1060 aluminum strip is mainly used for some high and low voltage electrical equipment, such as various transformer winding. This requires 1060 aluminum strip to have a high elongation, good crack resistance and uniformity. The tensile strength of 1060 aluminum strip can reach more than 135Mpa, the elongation rate can reach as high as 15%, and the finished product has good electrical conductivity, thermal conductivity and corrosion resistance.
1070 aluminum strip
It can be used to make dry-type transformers, oil-immersed transformers and reactor windings. The density of 1070 aluminum strip is 2.7 g/cm3, the tensile strength is 60-105 MPa, the elongation is 15-30% and the electrical conductivity is ≥65%IACS or ≥60%IACS, which can satisfies all the aluminum foil winding requirements.
1350 aluminum strip
1350 aluminum strip can be divided into two types: bare and coated. The bare type is mainly used as the winding material of the oil-immersed transformer, and the coated type is mainly used as the interlayer insulation material.
Features of 1350 aluminum foil strip
1. It has excellent elongation and tensile strength.
2. It is of good plasticity and uniform thickness. It has no burrs after stamping.
3. It has excellent electrical and thermal conductivity.
4. It has high temperature resistance, which can withstand 130 ℃ high temperature test.
As one of the big aluminum strip manufacturers for transformer, Haomei Aluminum has multiple aluminum strip cutting production lines, which can cut aluminum strips according to the width required by users. Edge chamfering can be 100% burr-free. Welcome to leave message below to inquire what you need.
