AWG 10 enameled aluminum wire is a specific gauge of enameled aluminum transformer winding wire. In the AWG (American Wire Gauge) standard, AWG 10 denotes a wire gauge of 10, which is a wire with a diameter of approximately 2.5882 mm (0.1019 in).

AWG 10 enameled aluminum wire has a diameter of approximately 2.5882 mm (0.1019 in). According to the AWG standard, the cross-sectional area of enameled aluminum wire is approximately 5.26 square millimeters (0.00814 square inches), which is calculated using standard formulas.


The relatively high resistance of enameled aluminum wire is due to the fact that aluminum has a lower electrical conductivity than copper. The conductivity of aluminum is about 61% of that of copper. Therefore, at the same current, the resistance of AWG 10 enameled aluminum wire will be higher than that of enameled copper wire of the same cross-sectional area.

The design of transformer coils requires consideration of the current rating of the coil. When using AWG 10 enameled aluminum wire, due to its higher resistance, it will have a slightly lower current rating than enameled copper wire of the same cross-sectional area. Therefore, when selecting winding wire, it is necessary to determine the appropriate wire size based on the design requirements and load rating of the transformer.

Enameled aluminum wire has a high coefficient of thermal expansion, so the effect of thermal expansion on the coil needs to be considered in the coil design. In addition, special care needs to be taken when connecting enameled aluminum wires, as contact between aluminum and copper may result in an electrochemical reaction, leading to an unstable connection or corrosion. Proper connection techniques and material selection are essential to ensure a reliable connection.

A number of industry standards and codes exist for transformer design and manufacture, such as those of the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE). These standards provide specifications and guidelines for transformer coil windings, including recommendations for conductor selection, insulation requirements, current loading, temperature ratings, etc.

It should be noted that the use and application of enameled aluminum wire needs to be determined by the specific transformer design requirements and application. During the design and manufacturing process, it is recommended to refer to relevant standards, technical guidelines and manufacturer's recommendations to ensure the performance, reliability and safety of the transformer coils.
