Transformers using 2mm pure 99.99% aluminum wound wire are a type of power transformer made with high purity aluminum conductors.

The 2mm pure 99.99% aluminum winding refers to the wire diameter of 2mm, and the material is 99.99% pure aluminum, the use of high purity aluminum conductor can provide good electrical conductivity performance, although the electrical conductivity of aluminum is relatively lower than that of copper, but for some low-current loading applications, high purity aluminum winding can meet the requirements.

Winding design is very important for transformer performance. For 2mm pure aluminum wound transformers, the winding design needs to be based on specific transformer parameters (e.g., transformer ratio, power, current, etc.) to ensure electrical performance and thermal management requirements.


Due to the poor thermal conductivity of aluminum, a transformer with aluminum winding may have a higher temperature rise relative to a copper conductor of the same cross-sectional area. Therefore, suitable thermal design and temperature management measures need to be considered when designing and manufacturing the transformer to ensure that the temperature of the transformer is within safe limits.

Transformers using 2mm pure 99.99% aluminum wound wire are usually suitable for low power or small to medium transformer application scenarios where the current is relatively low. Due to the high resistance of aluminum wire, careful calculation and design of wire diameter and winding is required to ensure that the required current load and resistance requirements are met.

For high power or high current loading transformer applications, copper conductors may be more common because copper has higher electrical conductivity and better thermal conductivity. When selecting and using wire materials, it is recommended to consult with a professional power engineer, equipment manufacturer, or a professional in a related field to ensure that the selection and use of wire meets specific requirements and standards.
