Aluminum Winding Wire

28 AWG aluminum enameled wire is a special type of conductor with an insulating enamel coating on the surface of the aluminum conductor. Its bare wire diameter is approximately 0.32 mm (the diameter increases slightly to 0.35-0.38 mm after enameling), offering the dual advantages of lightweight construction and superior insulation performance. Compared to traditional copper wire, aluminum has only 30% of the density of copper, resulting in a 50% weight reduction for the same conductive cross-sectional area, significantly reducing energy consumption in weight-sensitive fields such as aviation and new energy vehicle motors.

30 Swg Aluminum Winding Wire is a high-performance electromagnetic wire adhering to the British Standard Wire Gauge (swg), with a nominal diameter of approximately 0.254mm. Made of high-purity aluminum, it balances excellent electrical conductivity and thermal conductivity with the material’s inherent advantages of light weight and cost-effectiveness, making it a cost-efficient alternative to copper winding wire in many scenarios. Commonly used insulating varnish for 30 Swg Aluminum Winding Wire The selection of insulating varnish for 30 swg aluminum enameled wire is determined by its small diameter characteristic, low to medium power requirement, and miniaturized application scenarios. The most commonly used types are polyester-based insulating varnish and modified polyester-based insulating varnish.
