0.250mm Enamelled Round Copper Wire Class 220 Polyamide Imide Insulation Wire

Overview

2AIW-220 0.250mm 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 0.250mm 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.

Core Product Exclusive Advantages
