High-Quality Enameled Round Copper Wire

In the power industry, from high-efficiency motors and transformers to new energy vehicle drivetrains and industrial generators, the superior performance of equipment begins with a core component—the enameled round copper wire. As the carrier of current and the foundation of insulation, its quality directly determines the efficiency, reliability, and lifespan of the entire power system.

Flait Aluminum, as a leading provider of conductive material solutions, understands the critical importance of this core component. We are committed to supplying the global power industry with high-quality enameled round copper wire that meets the highest standards, safeguarding your innovation and high-efficiency applications.

Why Choose Flait Aluminum’s Enameled Round Copper Wire?

Our products strictly adhere to international standards (such as IEC, NEMA, JIS, etc.) and possess the following outstanding characteristics to meet the most demanding needs of the power industry:

✅ Excellent Insulation and Heat Resistance

Our enameled wires utilize high-quality insulating enamel coatings, such as common grades like Polyurethane (UEW), Polyester (PE), and Polyamide-imide (EIW). These coatings provide superior dielectric strength, effectively preventing inter-turn short circuits and ensuring stable operation under high voltage and high-frequency conditions. The heat resistance ratings range from Class 130 (B) to Class 220 (H) and above, enabling them to withstand high temperatures generated during the operation of electrical equipment, ensuring long-term reliability.

✅ Precise Dimensions and Consistency

We offer a wide range of conductor sizes, from fine 0.020mm to robust 4.0mm, meeting your diverse design needs from miniature precision instruments to large power equipment. Our strict control over diameter tolerance and ovality ensures smooth and consistent coil winding, which is key for automated mass production.

✅ Superior Mechanical and Chemical Stability

The enamel film exhibits excellent flexibility, adhesion, and scrape resistance, enabling it to withstand mechanical stresses during winding and insertion processes, preventing film damage. Additionally, the product demonstrates good resistance to common chemicals (such as refrigerants, lubricants, solvents, etc.), adapting to complex operating environments.

✅ Optimized Space Factor and Conductivity

The use of high-purity oxygen-free copper conductors guarantees very low resistivity and optimal conductivity, resulting in higher energy conversion efficiency. Meanwhile, the uniform and ultra-thin insulating enamel coating helps achieve a higher space factor, meaning more copper conductor can be accommodated within the same space, significantly improving the power density of the equipment.
