This is 24 SWG enameled copper wire with a thin layer of insulation. The insulation is made from modified Polyurethane with a polyamide overcoat that protects the coiled wire from short-circuiting. This enameled copper wire is made from pure and high-quality copper which provides good conductivity. It has good insulation, high-temperature resistance, good toughness, and tensile resistance, and it is not easy to break. Enameled copper is widely used in high-frequency transformers, inductor coils, relays, electric machines, electric motor coil winding, etc.
