White 2-4 Strips Combined Enamelled Copper Wire Magnet Wire For Coil Winding
WHITE 2-4 STRIPS COMBINED ENAMELED COPPER MAGNET WIRE FOR COIL WINDING
Magnet wire or enameled wire is a copper or aluminium wire coated with a very thin layer of insulation. It is used in the construction of transformers, inductors, motors, speakers, hard disk head actuators, electromagnets, and other applications that require tight coils of insulated wire.The wire itself is most often fully annealed, electrolytically refined copper. Aluminium magnet wire is sometimes used for large transformers and motors. The insulation is typically made of tough polymer film materials rather than enamel, as the name might suggest.
FEATURES AND APPLICATIONS
This product has high voltage resistance, high elasticity, good flexibility and tear resistance, moisture-proof, and good wear resistance, excellent corrosion acid and base resistance, it is suitable for coil windings of reactors and transformer
