Aluminum Alloys for Transformers: Performance and Applications
In power transmission and distribution systems, transformers play a vital role. And the performance of transformers depends largely on the quality and performance of its core component, aluminum strip.
What is transformer aluminum strip?
Transformer aluminum strip, also known as aluminum transformer foil strip, is mainly used for windings of dry-type transformers. It is a key component to ensure the electrical conductivity and mechanical strength required for efficient operation of transformers
Types of aluminum strip alloys
1000 series aluminum strip alloys:
Good electrical conductivity and formability, suitable for transformers with special requirements.
Commonly used transformer aluminum strips come from 1 series aluminum alloys, including 1050, 1060, 1070, etc. These alloys are selected because of their high purity and low impurities, ensuring the stability of their electrical and mechanical properties.
1050 aluminum alloy: With high conductivity and good processing performance, it is suitable for general transformers.
1060 aluminum alloy: With an aluminum content of more than 99.6%, it is widely used in high and low voltage windings of dry-type transformers.
1070 aluminum alloy: With a higher aluminum content, it provides excellent conductivity and processing performance.
1350 aluminum alloy: Also known as electrical aluminum, it has good electrical conductivity and mechanical properties and is suitable for a variety of transformers.
3000 series aluminum strip alloys (3003, 3105):
Known for good corrosion resistance and formability.
5000 series aluminum strip alloys (5052, 5083):
These alloys have high strength and good corrosion resistance.
Application fields of transformer aluminum strips
Transformer aluminum strips are widely used in various types of transformers, including:
Dry-type transformers: In dry-type transformers, aluminum strips are used to make high-voltage and low-voltage windings, and are favored for their good insulation and flame-retardant properties.
Oil-immersed transformers: In oil-immersed transformers, aluminum strips are also used for winding production, and their good heat resistance and corrosion resistance make them perform well in oil environments.
Distribution transformers: In distribution systems, aluminum strips are widely used because of their cost-effectiveness and good conductivity.
Transformer aluminum strips are an indispensable material in transformer manufacturing, and their performance directly affects the efficiency, reliability and economy of transformers. As the power system's requirements for transformer performance increase, it becomes particularly important to choose the right aluminum alloy material.
