Enameled wire, also known as insulated copper wire, features a pure copper core with a surface insulating paint and a polyester patent leather outer coating. The package includes 1 x enameled wire (500 g / 17.6 oz). Key benefits Direct welding capability: can be welded directly in assembly, saving time and reducing steps. Stable under frequency: designed to perform reliably in frequency applications. Portable and easy to handle: compact packaging and weightfriendly for easy transportation and storage. Durable insulation: robust insulation from the inner copper core through the outer coating. National standard specification: color coding in the system corresponds to wire diameter; copper wire follows national standard specifications. Material and construction Inner material: pure copper Insulation: surface insulating paint Outer finish: polyester patent leather coating Quantity: 1 x enameled wire (500 g / 17.6 oz) Electrical and thermal performance Withstand voltage: 3000 to 5000 V Temperature rating: 130 to 180 degrees Celsius Designed for direct welding and reliable performance in frequency environments Size and specification notes The color classification shown in the system refers to the wire diameter (specification). The copper wire adheres to national standard specification. Specification refers to the diameter of the drawn copper wire, i.e., the inner diameter before the paint film. Use scenarios Transformer and inductor winding: suitable for power transformers, inductors, and coilbased components. Motors and solenoids: appropriate for windings in small to medium motors or solenoids. DIY electronics and educational projects: ideal for hobbyist coil building, experiments with frequency circuits, and prototype development.
