Conductivity: 99.99% pure aluminum has good electrical conductivity, although it has a relatively lower conductivity than copper. This means that at the same current load, aluminum wire will have a higher resistance and power consumption. Therefore, when designing a transformer, the conductivity of aluminum wire needs to be considered to ensure the efficiency of current transfer and the performance of the transformer.

Temperature and Current Capacity: When using 2mm diameter aluminum wire to wind a transformer, attention needs to be paid to its temperature and current capacity limitations. Due to its poor thermal conductivity, aluminum wire may produce a higher temperature rise when subjected to the same current load as compared to copper conductors. Therefore, when designing a transformer, it is necessary to determine the appropriate current capacity and upper temperature limit based on the thermal conductivity of the aluminum wire and the transformer's heat dissipation system.


Weight and Cost: Compared to copper wire, aluminum wire with 99.99% purity is lighter and can reduce the overall weight of the transformer. In addition, aluminum is a relatively inexpensive metal, so the use of aluminum wire can reduce the manufacturing cost of a transformer to some extent.

Insulation: The surface of aluminum wire can be insulated with enamel or insulating coatings to ensure electrical insulation. This helps prevent current leakage or short circuits and improves the safety of the transformer.

Customization Options: Transformers can be customized to meet specific needs when wound with 2mm diameter 99.99% pure aluminum wire. This includes the number of coil turns, the winding method and the size of the transformer. Depending on the design requirements and application scenarios of the transformer, the appropriate wire diameter and winding method can be selected.

Factors such as current capacity, temperature limit, conductivity, thermal performance and cost need to be considered when selecting and using aluminum wire wound transformers. In addition, proper insulation and protection are important considerations to ensure transformer performance and safety. The optimum design and application solution should be determined by an experienced electrical engineer or a specialized manufacturer.
