30 swg wire

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.
