Rongdawire’s polyurethane film insulated round copper wire uses electrolytic copper (Cu 99.99%) as the conductor, coated with a polyurethane film for electrical insulation. The wire is designed for precision coil winding and high-frequency transformer applications, with fine gauges typically ranging from 0.05mm to 2.0mm in diameter. Its construction ensures superior electrical insulation, thermal resistance, and flexibility.
The wire’s polyurethane film insulation provides excellent mechanical strength and direct weldability, simplifying manufacturing processes for electronic components. Typical industry applications include micro motors, high-frequency transformers, headphones, speakers, and electromagnetic coils. The use of pure copper wire rods ensures effective current transmission with low resistance loss.
This product is widely sourced by electronics, automotive, and electrical equipment manufacturers for strict tolerance applications. Buyers should confirm the exact gauge, thermal class, and packaging requirements with Rongdawire, as these are not fully detailed in the listing. The wire’s flexibility and solderability make it ideal for miniaturized and high-precision components.
