Class 155 / 180 /220 0.02mm Magnte Wire Ultra Fine Copper Wire Enamel For Transformer
The conductor is the basic material of the enameled wire. Commonly used materials for conductors are copper, aluminum and other alloy materials. Usually the resistance in an electronic component is determined by the conductor. The cross-sectional area and length of the conductor affect the resistance.The insulating film is divided into single film and heavy film. Single film includes UEW, PEW, EIWHE AIW etc. Heavy film refers to an additional coating of nylon or self-adhesive paint on a single film.
Advantages Of Enameled Copper Wire
a) High resistance to heat shock.
b) High temperature.
c) Good performance in cut-through.
d) Suitable for high-speed automated routing.
e) Able to be direct weld, with no pinhole.
f) Resistive to high frequency, wearing, refrigerants and electronics corona.
g) High breakdown voltage, small dielectric loss angle.
h) Environment-friendly.
