Multi-Coated Enameled Copper Wire

By combining multiple enamel layers, this wire delivers outstanding durability and consistent electrical performance in demanding environments. Manufactured from high-purity electrolytic copper and insulated with dual or multi-layer enamel systems such as polyester, polyesterimide, and polyamide-imide combinations, this wire offers excellent dielectric strength and insulation integrity. It is available in commercial grades in accordance with IEC, NEMA, JIS, and GB standards, ensuring global compatibility and consistent quality. Multi-coated enameled copper wire is supplied mainly in round conductors, with size ranges from ultra-fine diameters around 0.02 mm up to larger gauges suitable for heavy-duty windings. Depending on the insulation system, it is offered in temperature classes 155°C, 180°C, 200°C, and up to 220°C. Key technical features include high abrasion resistance, superior cut-through strength, improved chemical resistance, uniform enamel thickness, excellent flexibility, and stable performance in high-speed automated winding processes.

Multi-Coated Enameled Copper Wire is widely used in high-efficiency electric motors, transformers, generators, compressors, automotive and EV motors, traction motors, and industrial coils where enhanced insulation safety is critical. It is especially suitable for compact designs, high voltage stress, and long-duty cycles. With its proven reliability, advanced insulation structure, and adaptability to harsh operating conditions, this wire provides a dependable and long-lasting solution for modern electrical and industrial manufacturing worldwide.
