5 Transformer Aluminum Strips How to Choose
The selection of specific 1-series aluminum strips should be comprehensively considered according to actual needs, and attention should be paid to factors such as material purity and surface treatment to ensure the performance and quality of the transformer.
Selecting transformer aluminum strip needs to consider many factors, such as application, electrical conductivity, strength and toughness, corrosion resistance and price, etc. In practical applications, it is necessary to select the most suitable material based on comprehensive consideration of specific application requirements and material properties.
Applications
Different types of transformer strips are suitable for different applications, such as coil materials for low-voltage transformers and oil-immersed transformers. When selecting a transformer aluminum strip, it is necessary to clarify its use scenario to ensure that the material can meet the application requirements.
1050 is mainly used for transformers with general requirements, such as generators, motors, etc.
1060, 1070 and 1100 are suitable for transformers with special requirements, such as high-precision, high-sensitivity, high-frequency transformers. 1235 is usually used for low-voltage electrical appliances.
Electrical Conductivity
Different types of transformer aluminum strips have different conductivity properties, and materials with high conductivity can reduce the resistance loss of the coil and improve the efficiency of the transformer. Therefore, when selecting transformer aluminum strips, it is necessary to select materials with appropriate conductivity according to specific application requirements.
1070 has the best conductivity
Strength and Toughness
The transformer aluminum strip needs to have sufficient strength and toughness in use to ensure that it can withstand the current and temperature changes inside the transformer. The strength and toughness of the material can be regulated by controlling its work hardening degree and heat treatment method. Therefore, when selecting the transformer aluminum strip, it is necessary to select the appropriate material according to the specific application requirements.
1070 has the highest intensity, followed by 1060, 1100, 1235 and 1050. The toughest is 1050, followed by 1060, 1100, 1235 and 1070.
Corrosion Resistance
Transformer aluminum strips need to have good corrosion resistance to avoid corrosion in use and lead to transformer performance degradation. The corrosion resistance of the material can be improved by selecting the appropriate alloy composition and surface treatment, so when selecting the transformer aluminum strip, its corrosion resistance needs to be considered.
1050, 1060, 1070, 1100 and 1235 have good corrosion resistance in general environment, but in some special environments, such as strong acid, strong alkali and other environments, their corrosion resistance may be different.
Price
Different types of transformer aluminum strips have different prices, and it is necessary to select materials with reasonable prices on the premise of meeting the application requirements. When selecting transformer aluminum strip, it is necessary to comprehensively consider its performance and price to achieve the goal of optimal cost performance.
The lowest price is 1050, followed by 1060, 1100, 1235 and 1070.
When selecting transformer aluminum strip, it is necessary to select the most suitable material based on comprehensive consideration of specific application requirements and material properties. At the same time, it is also necessary to pay attention to the source and quality of materials to ensure that they meet relevant standards and requirements, so as to ensure the safe and stable operation of the transformer.
