Wholesale 180 Class Enameled Flat Copper Wire Exporter, Exporters

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.

Enamelled wire is the main material for winding electromagnetic coils in industrial motors (including motors and generators), transformers, electrical instruments, power and electronic components, power tools, household appliances, automotive appliances and so on.

Product Description

Advantages of Enameled Rectangular Wire

Used in motor, network communications, smart home, new energy, automotive electronics, medical electronics, military electronics, aerospace technology and other fields.

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.

Rectangular enamelled wire products have simple structure, good heat dissipation performance, stable performance and good consistency.

Optimized temperature rise current and saturation current, combined with strong anti-electromagnetic interference capabilities.

Enables low vibration, low noise emission, and high-density component installation.

Ensures a highly efficient and high rate of groove filling for advanced winding systems.

The product ratio of the conductor section exceeds 97%. The corner paint film thickness is highly uniform and similar to the surface paint film, facilitating excellent coil insulation maintenance.

Delivers outstanding winding capabilities, strong bending resistance, and a flexible paint film that does not crack. Features a low incidence of pinholes and adapts to various winding methods.

Frequently Asked Questions

What are the main applications of Enameled Rectangular Wire?

Enameled Rectangular Wire is extensively used in motors, network communications, smart home systems, new energy solutions, automotive electronics, medical electronics, military electronics, and aerospace technology.

Why does rectangular wire offer a higher slot fill rate compared to round wire?

Its flat and rectangular geometry allows conductors to align tightly without leaving the wasted gaps inherent to round wire winding. This maximizes the space volume ratio and achieves a higher slot fill rate in the same winding space.

How does Enameled Rectangular Wire improve electrical performance?

By optimizing the conductor cross-section and minimizing gaps, it reduces electrical resistance. This allows higher current loads to pass through and provides a higher Q value, making it ideal for heavy current applications.

What are its thermal and physical insulation characteristics?

It has excellent heat dissipation, low vibration, and low noise properties. Structurally, the conductor section ratio exceeds 97%, and the corner paint thickness is identical to the flat surfaces, ensuring reliable coil insulation and stability.

Does the paint film crack during winding or bending?

No, the wire is designed with high winding flexibility and robust bending resistance. The protective insulation paint film remains intact without cracking, even when subject to diverse or complex winding methods, while maintaining a very low incidence of pinholes.
