CORE FEATURES

Round enamelled copper wires offer improved winding density and better space utilization compared to round wires. This can be crucial in applications where compactness and efficiency are essential.

Round coated copper wire size: 0.016-7mm; Customized according to customer requirements.

Anti-corona resistance: The anti-corona round copper magnet wire can work continuously in the environment of 200 degrees.

Insulated Copper Conductor: The copper wire is coated with a layer of enamel insulation, which provides electrical insulation and protects the wire from environmental factors such as moisture, chemicals, and abrasion.

Types of enamelled copper wire: single coating, heavy (double) coating, triple coating.

Copper wire thermal class:The thermal class ratings for aluminum wires are generally lower than those for copper wires due to aluminum's lower thermal conductivity.

Good resistance to heat and mechanical stresses, during coil winding, it is suitable for high mechanical stress and corrosive environments.

Long service life, it can withstand the corrosion of most copper alloys, making it the ideal choice for electromagnets.

Good ductility: the elongation rate of copper alloy is 20~40%, the elongation rate of copper for electricians is above 30%, and the aluminum alloy is only 18%.

Enameled Wire Manufacturing Process

All enamelled wires are enamelled on special enamelling machines which are developed and produced by LP for our exclusive use. Enamelling of enamelled wire is a continuous process, mainly consisting of the annealing process, enamel application, curing process, lubricant application, tension control and spooling.

Annealing Process

During the drawing process the bare wire’s grain structure has been changed through cold deformation. Annealing will re-crystalize the copper and make it
