Overview
This Class 220 AI Enameled Flat Copper Wire is our top-grade ultra-high temperature resistant winding wire, professionally developed for extreme working conditions of high-load, high-power and long-term continuous operating precision equipment. Adopting premium Polyamide-imide (AI) pure insulation material, it achieves a super high heat resistance grade of 220℃, far exceeding conventional EI and EI/AI composite wires. With unique brick-like flat structure, it realizes over 90% ultra-high slot fill factor, effectively reduces copper loss, eliminates internal air gaps and accelerates heat dissipation. It comprehensively optimizes motor electric field, magnetic field and thermal field, enabling miniaturized motors to maintain stable and efficient output under high temperature and high-load extreme environments.
