Polyesterimide Base Enamelled Copper Wire

Manufactured from high-purity electrolytic copper and coated with advanced polyesterimide enamel, this wire delivers excellent thermal endurance and mechanical strength. It is commonly available in commercial grades compliant with IEC, NEMA, JIS, and GB standards, ensuring global usability and consistent quality. Polyesterimide enamelled copper wire is supplied mainly in round cross-sections, with size ranges from fine diameters around 0.04 mm up to heavy gauges suitable for high-power windings. The wire is typically offered in temperature classes 180°C and 200°C, making it suitable for continuous operation under elevated thermal stress. Key technical features include high dielectric strength, superior resistance to abrasion and chemicals, uniform enamel thickness, excellent winding performance, and strong resistance to thermal aging. These characteristics ensure reliable insulation integrity even in compact, high-speed winding designs.
