0.350mm Enameled Copper Wire Class 220 Polyamide Imide AI Ultra High Temperature Resistant

2AIW-220 0.350mm Enameled Copper Wire is our top-grade ultra-high temperature round winding wire, standardized by international 2AIW-220 specification, adopting imported pure Polyamide-imide (AI) insulation material with Class 220 heat resistance. Compared with conventional EI / EI/AI composite enameled wire, this wire owns premium insulation strength, anti-thermal aging and anti-corrosion performance. With fixed 0.350mm precise wire diameter, uniform paint film, strong adhesion and outstanding secondary softening property, it keeps stable running performance under long-term high-frequency, high-temperature and high-load working conditions, matched for high-end precision industrial winding components.

• Standard 2AIW-220 Spec: International standard model 2AIW-220, fixed precise wire diameter 0.350mm, fully compliant with global motor coil assembly standards, easy matching for customer automatic winding equipment.
• Class220 Ultra-high Heat Resistance: Pure Polyamide-imide AI insulation layer, sustainable 220℃ operating temperature, anti-thermal decomposition, not easy aging under continuous high-load operation.
• Super Strong Paint Film Adhesion: Integrated enamel coating process, crack-proof, peel-proof during high-speed winding, reduce coil defective rate greatly.
• Excellent Secondary Softening Performance: Easy thermal shaping and fixed forming, perfect for automated coil processing, improve production efficiency for manufacturers.
• Ultra-stable Conductive Performance: Adopt high-purity oxygen-free copper conductor, low resistivity, stable current transmission, no heat runaway or performance deviation.
• Full Industrial-grade Certifications: Passed UL, RoHS, ISO, IATF automotive & industrial grade certification, no customs clearance risk for global export orders.
