Product overview Enameled wire also known as insulated copper wire. It has a pure copper inner core with a surface insulating coating described as polyester patent leather and paint. Packaged as 1 x enameled wire (500 g / 17.6 oz). Key benefits Direct welding compatible: can be welded directly for fast, reliable connections. frequency ready: designed to perform well in frequency applications. Portable and easy to handle: convenient to carry and work with in projects. voltage and temperature tolerance: voltage withstand 3000 to 5000 V; temperature tolerance 130 to 180 C. Clear specifications by diameter: color classification corresponds to wire diameter (spec), and the copper wire meets national standard specifications. Drawn wire diameter defined: specification refers to the diameter of the drawn copper wire, i.e., the inner diameter before the paint film. Technical details at a glance Product: enameled wire (insulated copper wire) Core: pure copper Surface coating: insulating paint (polyester patent leather) Packing: 1 x enameled wire (500 g / 17.6 oz) Voltage rating: 3000 V – 5000 V Temperature range: 130 – 180 C Color/spec classification: refers to wire diameter; national standard copper wire specification Specification note: diameter refers to drawn copper wire, inner diameter without paint film Practical applications Transformer and inductor winding: suitable for coil building and winding tasks in small to medium electronics projects. Motor and equipment repairs: useful for rewinding or repairing windings where enamel insulation is required. DIY electronics prototypes: ideal for experiments and prototype circuits needing reliable enamel coated copper wire. Why this matters You get a durable, performance enamel coated copper wire that is easy to work with, supports voltage and elevated temperatures, and is appropriate for direct welding and frequency use. The specification system clearly communicates the copper wire diameter to ensure you choose the right size for your application.
