Product: enameled wire (insulated copper wire). Inner layer of pure copper with surface insulating paint. Outer coating is polyester patent leather. Packing: 1 x enameled wire (500g/17.6oz) Key benefits It can be welded directly without removing the coating, simplifying assembly. Designed to resist frequency operation for reliable performance. Lightweight and compact for convenient use in the field or at the workbench. Specifications and features Product type: enameled wire, insulated copper wire with pure copper core. Insulation and coating: surface insulating paint with polyester patent leather. Packing: 1 x enameled wire (500g/17.6oz) Temperature resistance: suitable for temperatures in the range of 130 to 180 degrees Celsius. Voltage rating: voltage resistance up to 3000V to 5000V. Capable of being directly welded, suitable for frequency applications. Designed to be easy to carry and use in various settings. Size and standards Color classification indicates the wire diameter (specification) as shown by the system. The copper wire conforms to national standard specifications. Specification refers to the diameter of the drawn copper wire, that is, the inner diameter without the paint film. Notes on interpretation of specifications The specification refers to the diameter of the drawn copper wire, representing the inner diameter before applying the paint film. Applications and use scenarios Coil winding for inductors and transformers: use the enameled wire to create windings that require insulation and stability at higher frequencies. frequency assemblies and compact electronics: suitable for devices where insulation performance and frequency resistance are important. DIY electronics, repairs, and prototyping: convenient for projects that need a readytowind copper conductor with reliable insulation and direct welding capability.
