The Properties of Aluminum Strip for Transformer Winding
Aluminum strip for transformer winding is commonly used in the power transformer making, and its performance directly affects the service life and safety performance of the transformer. This article will introduce in detail the status of transformer aluminum strip from multiple angles.
1. Chemical composition
The chemical composition of the transformer aluminum strip is one of the important factors affecting its performance. Its main components are aluminum, silicon, copper, magnesium and other elements. The content of copper and magnesium has an important impact on the hardness, strength and conductive properties of the alloy.
2. Structure and morphology
The structure and morphology of aluminum transformer strip is another important factor in its performance. Its structure mainly has two forms: equiaxed crystal and columnar crystal. Among them, equiaxed crystal has better thermal stability and electrical conductivity. At the same time, dimensional parameters such as thickness, width and length of the aluminum strip will also have a certain impact on its performance.
3. Mechanical properties
The mechanical properties of aluminum strip for transformer include elastic modulus, yield strength, fracture toughness and other indicators. Among them, the elastic modulus is the material's ability to resist bending and shear deformation, the yield strength is the stress level at which the material begins to undergo plastic deformation, and the fracture toughness reflects the energy absorbed by the material before fracture.
4. Thermal conductivity
The thermal stability of the aluminum strip refers to its stable performance under long-term high temperature conditions. Since the transformer will be affected by higher temperatures when operating, the thermal stability of the aluminum strip alloy is of great significance to its service life and safety performance.
5. Corrosion resistance
The corrosion resistance of aluminum strips for sale refers to its stable performance in humid or corrosive environments. Since transformers are usually installed in outdoor environments, the corrosion resistance of aluminum strip alloys has a significant impact on their service life.
6. Manufacturing process
The manufacturing process of transformer aluminum strip alloy will also have a certain impact on its performance. Among them, the rolling process, heat treatment process and cooling process of the aluminum strip will all affect its structure and performance.
In summary, the alloy state of the transformer aluminum strip has an important impact on the service life and safety performance of the power transformer. Haomei Aluminum offers pure aluminum strips for transformer.
