Enameled Fine Copper Wire 0.012mm to 0.8mm For Winding
Enameled round copper wire makes enamel film and copper conductor. Because of properties in mind like abrasion resistance, solderability, because of its thermal rating, the wires widely use in electric equipment in our lives. More machine use the wire, because thermal Class from 105 to 240°C, and service life at rated temperature for 20,000 hours.
Because of thermal class, density, oxidation resistance, sercive life, the wire uses for the construction of transformers, inductors, speaker coils, and other electrical devices.
