Enamelled Flat Wire

Short Description:

Enameled rectangular wire is an enamelled rectangular conductor with an R Angle. It is described by the narrow edge value of the conductor, the wide edge value of the conductor, the heat resistance grade of the paint film and the thickness and type of the paint film. Conductors can be copper or aluminum. Compared with round wire, rectangular wire has incomparable advantages and characteristics and is used in many fields.

Conductor Material

● Once the raw material of winding wires is softened copper,the regulation in accordance with GB5584.2-85,the electric resistivity at 20C is lower than 0.017240.mm/m.

● As per different mechanical strength,the non-proportional extension strength of semi-rigid copper conductor Rp0.2(>100~180)N/mmRp0.2(>180~220)N/m㎡Rp0.2(>220~260)N/m㎡

● Once the raw material of winding wires is softened aluminum,the regulation in accordance with GB5584.3-85,the electric resistivity at 20C is lower than 0.02801Ω.mm/m

As per different requirement of electrical insulation,the thickness of paint will be available for 0.06-0.11mm or 0.12-0.16mm,the thickness of self-adhere layer for thermal bonding winding wires is 0.03-0.06mm.The optical loss test facility named TD11 can be used for screening the coating process,in order to reach the best cured coating.

Any further requirement for the thickness of coating,please kindly inform us in advance.

Advantages of Enameled Rectangular Wire

1. Meet the design needs of lower height, smaller volume, lighter weight, higher power density of electronic and motor products, widely used in electronics, electrical appliances, motor, network communications, smart home, new energy, automotive electronics, medical electronics, military electronics, aerospace technology and other fields.

2. Under the same cross-sectional area, it has a larger surface area than the round enamelled wire, which can effectively reduce the "skin effect", reduce the high-frequency current loss, and better adapt to the high-frequency conduction work.

3. In the same winding space,  the application of rectangular enamelled wire makes the coil slot full rate and space volume ratio higher; Effectively reduce the resistance, through larger current, higher Q value can be obtained, more suitable for high current load work.

4. The application of rectangular enamelled wire products, which have simple structure, good heat dissipation performance, stable performance,good consistency, can still maintain well in high frequency and high temperature environment.

5. Temperature rise current and saturation current; Strong anti-electromagnetic interference (EMI), low vibration, low noise, high density installation.

6. High rate of groove filling.

7. The product ratio of conductor section is more than 97%. The thickness of the corner paint film is similar to that of the surface paint film, which is conducive to coil insulation maintenance.

8. Good winding, strong bending resistance, paint film winding does not crack. Low incidence of pinhole, good winding performance, can adapt to a variety of different winding methods.

Application of Enameled Rectangular Wire

● Enamelled flat wire is used on power transformer, AC UHV transformer and DC converter transformer.

● Heat-resistant enameled rectangular wire is used for dry type transformer.

● Electric motors, generators and new energy vehicles.
