Import Enameled Copper Wire — Buy in Bulk from Supplier in China

This supplier offers round enameled copper wire with diameters ranging from 0.10mm to 4.50mm, designed for electromagnetic windings in motors, transformers, and inductors. The conductor is made from electrolytic copper and coated with a polyesterimide enamel, providing high thermal stability and mechanical durability under continuous operation. The product is suited for automated winding machines due to its consistent diameter and smooth surface.

The polyesterimide enamel coating provides superior resistance to thermal cycling and chemical exposure compared to standard polyester systems. Typical thermal classes are 155°C and 180°C, with insulation thickness calibrated to the wire gauge to ensure dielectric integrity. The wire maintains flexibility even at low temperatures, allowing for tight bends during coil formation without cracking the insulation layer.

This wire is commonly used in automotive starters, HVAC compressors, and power supply transformers where reliability under load is critical. Buyers in the electronics manufacturing and industrial equipment sectors source this product for high-volume coil production. Packaging is on plastic or wooden spools, with standard weights of 1kg to 25kg. Trade terms are flexible for bulk orders, but MOQ, lead time, and packaging must be confirmed directly with the supplier.
