2UEW-F 0.15mm Solderable Wire Copper Enameled Magnet Wire
Enamelled copper wire is an important component in industrial and audio applications. Its unique properties, including high electrical conductivity, mechanical flexibility and heat resistance, make it an indispensable material for manufacturers. The wire is 0.15 mm in diameter and features a polyurethane paint film for enhanced durability, designed to meet the demands of modern electrical systems. Whether used in motors, transformers or audio equipment, enameled copper wire remains the cornerstone of innovation in the electrical and electronics industry.
·IEC 60317-20
·NEMA MW 79
·customized according to customer requirements.
One of the outstanding properties of enameled copper wire is its excellent electrical conductivity, which is essential for efficient energy transmission in electrical applications. The copper core provides a low-resistance path for electrical current, while the enamel coating acts as an effective insulator, preventing short circuits and ensuring safety. The polyurethane paint film not only enhances the wire’s durability, it also improves its solderability, making it easier to connect to other components in the circuit. This combination of properties makes enameled copper wire the first choice for manufacturers looking to produce high-quality electrical equipment.
