What is the 1070 O aluminum foil for transformer winding? - hmwadeseo - 07-18-2023
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:
1. Good plasticity after annealing;
2. Easy to process and weld;
3. Excellent corrosion resistance;
4. High conductivity and thermal conductivity;
5. Low strength;
6. Good elongation (≥20%) and other characteristics.
