Film enameled wire, also known as Mylar wire, "Mylar" is the phonetic translation of "Mylar". It is the world's first PET film successfully developed and industrialized by DuPont. Enameled wire is in the Leeds wire, enameled stranded wire outside the addition of one or more layers of Mylar film to improve the insulation voltage of the wire+, but also play a shielding role, can be a substitute for wire wrapping.

Coated wire, in the wire or enameled stranded wire surface according to a certain overlap rate coated with synthetic film or other materials film as an insulating layer of electromagnetic wire.


Advantages and characteristics of coated enameled wire
1、Good high frequency performance.
2, good resistance to high temperature and high pressure performance.
3, good flexibility, strong resistance to mechanical stress.
4. Good waterproof and anti-insulating oil performance, suitable for use in sealed environments.
5. Heat-resistant temperature and voltage of 130°C (Class B) and 155°C (Class F)
6. Dielectric strength up to 6KV/5MA/1Min
7. Coefficient of friction 1.4-4.13 times higher than ordinary insulated wires.
8. Insulation coefficient better than ordinary insulated wire, production design can reduce the primary and secondary retaining walls.

Enameled wire specifications: overlap
Rate: the ratio of the area covered by the front loop film by the back loop film to the total area when wrapped, usually there are three kinds: 50%, 67% and 75%.
Range of number of strands: 1~36000 strands (different specifications, according to the cross-sectional area)
Range of finished outer diameter: 0.25~6mm
Cross-sectional area: max. 20mm²
Enameled single wire (nominal diameter of conductor): 0.02~0.50mm

Due to high temperature resistance and high insulation, they are widely used in high frequency transformers, high power transformers, magnetic rings, medical devices, inverters, high frequency inductors and transformers, and wireless chargers.
