Polyester Base Enamelled Copper Wire

Produced from electrolytic grade copper and coated with high-quality polyester enamel, this wire offers excellent electrical insulation, smooth surface finish, and uniform enamel thickness. It is available in commercial grades compliant with IEC, NEMA, JIS, and GB standards, ensuring global acceptance and easy integration into existing designs. Polyester base enamelled copper wire is typically supplied in round cross-sections, with a broad size range from fine gauges (approximately 0.04 mm) to larger diameters suitable for power applications. The wire is commonly offered in temperature class 130°C, providing dependable thermal endurance for continuous operation. Key technical features include good dielectric strength, reliable mechanical flexibility, consistent winding behavior, and resistance to common winding stresses. Its balanced properties make it ideal for high-speed winding processes and mass production environments.
