Polyamide-Imide Base Enamelled Copper Wire

Manufactured from high-purity electrolytic copper and coated with advanced polyamide-imide enamel, this wire provides outstanding resistance to heat, abrasion, chemicals, and thermal aging. It is available in commercial grades meeting IEC, NEMA, JIS, and GB standards, ensuring consistent quality and global compatibility. Polyamide-imide enamelled copper wire is supplied mainly in round cross-sections, with sizes ranging from fine diameters around 0.04 mm up to heavy gauges for high-power windings. It is commonly offered in temperature classes 200°C and 220°C, suitable for continuous operation under extreme thermal stress. Key technical features include very high dielectric strength, superior cut-through resistance, excellent flexibility for tight winding, strong bonding capability, and reliable performance in high-speed automated winding processes.
