2UEW155 0.15mm Enameled Coated Copper Wire Magnetic Wire
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.
