Key benefits Direct welding capability: can be directly welded, enabling fast connections in circuits and assemblies. voltage tolerance: voltage class 3000V 5000V supports demanding electrical applications. Wide temperature range: temperature resistance 130 180 degrees, suitable for varied environments. Durable insulation: inner layer of pure copper with surface insulating paint and polyester patent leather for reliable insulation. Portable and convenient: packing is 1 piece x enameled wire (500g/17.6oz), easy to carry. frequency readiness: designed for frequency resistance applications. What it is Product: enameled wire, also known as insulated copper wire. Construction Inner core: pure copper. Outer coating: surface insulating paint, polyester patent leather. Size and classification notes Color classification displayed by the system refers to the wire diameter (specification), and the copper wire is the national standard specification. Gauge refers to the diameter of the bent copper wire, i.e., the inner diameter without paint film. Packing 1 piece x enameled wire (500g/17.6oz) Voltage and temperature characteristics Temperature class: 3000V 5000V voltage, temperature resistance 130 180 degrees. Key feature: can be directly welded, frequency resistance, easy to carry. Use scenarios Electronics prototyping and projects that require enamel coated copper wire with direct weldability. Winding coils for transformers, inductors, motors, or solenoids in small electronics. frequency circuit work where insulation, weldability, and portability are important.
