Enameled Flat Copper Wire

Enameled flat copper wire is a highly conductive enameled flat copper wire suitable for winding motors, transformers, and electronic coils.

Enameled flat copper wire is made of high-purity oxygen-free copper and is coated with insulating varnish.

Applying 5–13 layers of insulating varnish and curing them with a mold or felt method tightly bonds the copper wire layers into an integral structure.

Available in flat or rectangular cross-sections, with thicknesses ranging from 0.80–5.60mm and widths from 2.00–16.00mm, suitable for compact winding designs.

The surface insulation material of enameled flat copper wire is coated with an insulating paint film that is resistant to high temperatures, solvents, and oils. Common types include polyester (PE), polyamide (PI), and polyesterimide (PVF).

High Conductivity
Enameled flat copper wire utilizes oxygen-free copper with a copper content of ≥99.97%, achieving a conductivity of 58 MS/m, improving motor efficiency.

High Dimensional Accuracy
Multi-mode wire drawing and precision rolling on a French REDEX rolling mill ensure dimensional accuracy of ±1 μm, resulting in a smooth, flat cross-section and tightly arranged windings without deviation.

Extrusion Process

 

High axial pressure presses the copper rod into the die, forming bare copper wire of the desired cross-sectional dimensions and ensuring a dense and uniform wire.

Wire Drawing Process

 

Utilizing multi-die wire drawing technology, the roller speed and current in 1 to 8 die stages are precisely controlled by adjusting tension and ratio, achieving dimensional accuracy and stable operation.

Rolling Process

 

Precision grinding using the French REDEX rolling mill ensures uniform copper rod diameter, smooth surface, dense microstructure, and minimal defects.

The rolling speed can reach 400 meters per minute, with efficiency approximately four times that of conventional equipment, meeting the demands for efficient production of enameled, coated, and paper-covered wire.

 

Combining high-resolution cameras, strong lighting, and machine learning, this system can detect cosmetic and physical defects (such as particles, color variations, scratches, embossing, bubbles, and foreign matter) in painted flat wires.

Both missed and false positive rates are less than 1%.

A: Yes. We provide standard samples for testing purposes, and some samples are provided free of charge. Shipping costs are borne by the customer.

Q: How does enameled flat copper wire work?
A: Enameled flat copper wire uses an insulating varnish layer to isolate the conductors, ensuring safe current transmission and electromagnetic conversion, and ensuring stable coil operation.

Q: What devices are these magnet wires commonly used for?
A: These magnet wires are primarily used in motors, transformers, generators, and new energy vehicle motors, providing efficient electrical conductivity.

Q: How should enameled flat copper wire be properly stored?
A: When storing, keep it dry and out of direct sunlight and chemically corrosive environments to prevent aging of the varnish and oxidation of the copper surface.

Q: What precautions should be taken when cleaning enameled flat copper wire?
A: When cleaning, use a non-corrosive solvent and avoid scratching with hard objects to prevent damage to the varnish insulation layer.
