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.
