200 Class Enameled Flat Copper Wire

Short Description:

As an industrial conductor be applied on the winding of transformer, electric motor, generator and various electric equipment, the enameled rectangular winding wires are extruded and draw out from oxygen-free copper rod or aluminum and aluminum allays rod by means of specific mold, then winded after coated by insulated paint.

The enamelled flat copper wire produced by our company is suitable for driving motors, transformers, motors, generators and winding coils of various electrical devices of new energy vehicles.

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. Effectively reduce the resistance, through larger current, higher Q value can be obtained, more suitable for high current load work.

4. Have simple structure, good heat dissipation performance, stable performance,good consistency, can still maintain well in high frequency and high temperature environment.

5. 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.

8. Low incidence of pinhole, good winding performance, can adapt to a variety of different winding methods.
