Polyurethane Base Enameled Copper Wire

Polyurethane Base Enameled Copper Wire is a premium winding wire engineered for high performance, reliability, and ease of processing in modern electrical and electronic applications. Thanks to its excellent balance of electrical, mechanical, and thermal properties, it is one of the most widely used enameled copper wires in global markets.

Manufactured from high-purity electrolytic copper and coated with a high-quality polyurethane enamel, this wire offers outstanding solderability, flexibility, and surface smoothness. One of its key advantages is direct solderability without removing insulation, which significantly reduces production time and cost. Polyurethane enameled copper wire is available in commercial grades conforming to IEC, NEMA, JIS, and other international standards, ensuring compatibility with diverse industrial requirements. The wire is commonly supplied in round cross-sections, with sizes ranging from ultra-fine diameters (starting from approx. 0.02 mm) up to several millimeters, suitable for both precision and general-purpose windings. It is offered in temperature classes 130°C and 155°C, making it ideal for applications requiring moderate thermal resistance. Additional technical features include excellent dielectric strength, good abrasion resistance, uniform enamel thickness, and stable performance under continuous electrical stress.

Polyurethane Base Enameled Copper Wire is widely used in small and medium electric motors, transformers, relays, solenoids, ignition coils, sensors, audio coils, and electronic components where compact design and reliable solder joints are critical. Its superior winding ability allows for tight coil formation and consistent performance in high-speed winding processes. With reliable insulation integrity, low defect rates, and proven long-term stability, this wire is a cost-effective and trusted solution for manufacturers seeking quality, efficiency, and compliance in competitive global markets.
