Product: enameled wire (also known as insulated copper wire). The inner core is pure copper, with a surface insulating paint and polyester patent leather finish. Packing: 1 piece x enameled wire (500 g / 17.6 oz). Key benefits voltage tolerance: rated for 3000 to 5000 V, enabling use in higher voltage applications without additional insulation. Strong insulation and durability: pure copper core with robust surface coating for reliable insulation. Direct welding capability: can be welded directly, supporting quick assembly and . Good frequency performance: designed to maintain stable performance at higher frequencies. Portable and convenient: supplied as a single piece with a substantial mass for easy handling. How to read the specifications Color classification: refers to wire diameter (the specification). The copper wire conforms to national standard specifications. Gauge: refers to the diameter of the bent copper wire, i.e., the inner diameter without the paint film. Material and construction: inner layer of pure copper; surface insulating paint; polyester patent leather coating. Packing: 1 piece of enameled wire, weight about 500 g (17.6 oz). Technical specifications Product: enameled wire (insulated copper wire) Core material: pure copper Coating: surface insulating paint; polyester patent leather Packing quantity: 1 piece x enameled wire (500 g / 17.6 oz) Voltage rating: 3000–5000 V Temperature rating: 130–180 degrees C Key feature: can be directly welded Performance note: suitable for frequency applications and easy to transport Applications and use scenarios Coil windings for transformers, inductors, and motors requiring durable insulation and directweld capability.
