Material
Using high-purity oxygen-free copper (OFC) exceeding 99.99%.
Bonding
Enameled round copper wire is bonded by a self-adhesive layer, which fuses the coils together when heat or solvent is applied.
Shape
Enameled round copper wire is a round, solid copper wire with a smooth surface, uniform cross-section, and no pores or cracks.
insulation material
Enameled round copper wire is coated with an insulating varnish such as polyester varnish (PVF) or polyimide varnish.
Bare wire enameling process
Extrusion Process
During the initial forming process of enameled round copper wire, a copper rod is extruded through a die under high axial pressure, reducing its cross-section to form the initial copper wire and ensuring a uniform wire structure.
Wire Drawing Process
During the wire drawing process, the copper rods are drawn through multi-stage dies. Precisely controlled roller speed, current, tension, and linkage ratio ensure accurate wire dimensions and a smooth surface.
Rolling Process
During the rolling process of enameled round copper wire, French REDEX rolling mill equipped with precision grinder is used to ensure uniform diameter of copper rod, smooth surface of conductor, few defects and dense internal structure.
Enamelling
The production line uses advanced Austrian MAG equipment to precisely control wire pay-off, furnace temperature, and paint baking to produce high-quality enameled wire.
Packing Reference
Cylindrical wooden or plastic spools, tapered spools, wooden pallets (domestic or IPPC export standards), wooden boxes, or Euro pallets are available to suit your shipping and storage needs.
Shipping Options
enameled round copper wire can be delivered by sea, air and road.
Frequently Asked Questions
Q: How long is your delivery time?
A: Typically, it takes 2-4 weeks, depending on the order quantity and degree of customization. For urgent orders, we can prioritize production.
Q: How is your price calculated?
A: Prices depend on wire specifications, material, quantity, and process requirements. We will provide a formal quotation after confirming your detailed requirements.
Q: What payment methods do you accept?
A: We typically accept common international payment methods such as T/T (Wire Transfer) and L/C (Letter of Credit). Long-term customers can negotiate more flexible payment terms.
Q: What if there is a problem with the product I receive?
A: Please contact us immediately upon receipt. We will promptly investigate the cause and provide a return, exchange, or reissue service to ensure your safety.
Q: Do you provide samples?
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: What is the main use of enameled round copper wire?
A: It is primarily used in windings for motors, transformers, inductors, and electronic devices, providing stable conductivity.
Q: How do you clean enameled copper wire?
A: It can be cleaned with a dry cloth. Cleaning with strong acids or alkalis is not recommended to avoid damaging the varnish.
Q: What precautions should be taken during installation?
A: Avoid excessive stretching and sharp bends to prevent damage to the varnish and compromise insulation.
Q: Can it be stored long-term?
A: Yes, the coiled packaging is moisture-proof and maintains stable performance.
Q: Can it be processed into different lengths?
A: We can cut or customize the reel lengths to meet the needs of different equipment windings.
