YAWEI’s 220 Grade Polyamide-Imide Enameled Copper (Aluminum) Rectangular Wire is a high-performance electromagnetic winding wire engineered for extreme operating conditions. This industry-leading enameled wire combines class 220 thermal stability with exceptional mechanical, chemical, and environmental resistance, making it the preferred choice for commercial and industrial clients requiring reliable, long-lasting winding solutions. Available in both copper and aluminum conductor options, our rectangular wire optimizes slot fill efficiency, reduces equipment footprint, and delivers consistent performance in high-stress electrical applications.
Our high-temperature polyamide-imide enameled wire supports continuous operation at 220°C, with outstanding low-temperature tolerance down to -60°C, radiation resistance, and refrigerant compatibility. It withstands harsh chemical exposure and overload conditions, eliminating premature insulation failure and reducing unplanned downtime for your equipment.
With high tensile strength, excellent scrape resistance, and stable dielectric properties, this rectangular wire simplifies high-speed winding processes, minimizes breakage during manufacturing, and maintains stable electrical performance across variable load cycles. Its flat profile maximizes conductive area in limited spaces, enabling more compact, energy-efficient equipment designs.
By extending equipment service life, reducing maintenance requirements, and improving energy efficiency, our enameled wire delivers long-term cost savings for industrial manufacturers. The dual copper/aluminum material options allow you to balance performance and budget without compromising on quality or compliance.
