Enameled copper flat wire is a bare copper flat wire obtained after round copper wire is drawn, extruded or rolled by a die, and then coated with insulating varnish for many times. The surface layer of the painted flat copper wire has good insulation and corrosion resistance. Compared with the ordinary round-section enameled wire, the enameled flat wire has excellent current carrying capacity, transmission speed, heat dissipation performance and occupied space volume. performance.

1) Suitable for winding in high speed machines
2) Very good resistance to transformer oils
3) Very good resistance to typical solvent
4) Freon resistant
5) Excellent resistance to mechanical stress
1.The similar square coil has very small gap and better heat sink performance.
2.Compared with round wire coils of the same size, similar square coils have smaller R angle.
3.Higher space factor, DCR can be reduced by 15%-20%,current increases, thereby increasing power and reducing heat generation.
Typical applications of enameled square wire are smart watches, smart phones, electronic transformers, UPS power supply, generator, motor, welder, etc.
