Transformer Winding Aluminium Strips: The Ultimate Guide
Aluminum strips are one of the most important metal materials in transformer winding industry.
When you choose to buy transformer aluminum strips, there have some important points we need to know before we get started.
What are the grades of transformers aluminum strips?
1.What is the 1050 O aluminum strip in a transformer?
The 1050 O aluminum strip in a transformer is the most commonly used material in transformers.
The reason why it can be widely used in transformers is related to its excellent properties.
1050 O aluminum strip has high electrical conductivity and thermal conductivity. In the actual application process of transformers, 1050 O aluminum strips are often used as support materials to form transformer windings, which can reduce the loss of transformers and improve the performance of transformers.
The thickness of the 1050 O aluminum strip in a transformer is generally between 0.1 mm and 1 mm. It adopts a single-layer or double-layer structure, which can effectively reduce the leakage magnetic field of the coil and improve its insulation performance.
The transformer 1050 O aluminum strip is a kind of connecting material for winding coils, which is wound on the coil in a certain way to form a specific inductance, mutual inductance or distributed capacitance. In addition to this kind of connection material, there are other forms of connection between coil turns, such as soldering connections and welding connections.
2.What is the 1060 O aluminum strip for transformer winding?
1060 O aluminum strip for transformer winding, the content is 99.6%, mainly used for some high and low voltage electrical equipment, such as various transformers winding. The common state is O state, so it is also called aluminum strip for transformer winding.
The aluminum strip in the electrical equipment industry has very high requirements on its performance, which requires the flexibility of the aluminum belt to be good enough.
This requires that the 1060 O aluminum strip for transformer winding has a very high elongation. In addition, it should have a good crack resistance and uniformity. meet
1060 O aluminum strip for transformer winding is mainly made of 1 series pure aluminum strip product, tensile strength can reach more than 135Mpa, elongation is up to 15%, the finished product has good electrical conductivity, thermal conductivity and corrosion resistance.
1060 O aluminum alloy has high plasticity, corrosion resistance, electrical conductivity and thermal conductivity. But they have lower strength than other alloys.
1060 O aluminum strip has high plasticity at annealed state and hardening phenomenon in semi cold hardening, good corrosion resistance, good weldability, poor machinability, but with extrusion and stretch forming high performance. The electrical conductivity of 1060 O strip is about 60%IACS. The density is 2.7 g/cm3.
3.What is the 1070 O aluminum foil for transformer winding?
The 1070 O aluminum foil for transformer winding has the advantages of high conductivity, good corrosion resistance, high thermal conductivity and large extension ratio.
The annealing state is O.
The 1070 O aluminum foil for transformer winding can be used to make dry-type transformers, oil-immersed transformers and reactor windings.
The 1070 O aluminum foil for transformer winding has a density of 2.7 g/cm3 and the tensile strength is 60-105 MPa, which can meet the strength requirement of aluminum foil winding.
The elongation is 15-30%, which can meet the elongation requirement of aluminum foil winding. The electrical conductivity is ≥65%IACS or ≥60%IACS.
The 1070 O aluminum foil for transformer winding has good heat dissipation and does not increase the temperature rise of the coil during long-term operation, thus prolonging the service life of the coil. The use of 1070 O aluminum foil for transformer winding can reduce the mass manufacturing cost of transformers by 15%.
Advantages of 1070 O aluminum foil for transformer winding:
