Manufacturing Process
Drawing
High-purity copper rod is fed through a series of precision drawing dies to reduce its diameter and achieve the required conductor size. This process improves dimensional accuracy, surface quality, and electrical performance while maintaining excellent conductivity.
Bunching
Multiple fine copper wires are twisted together to form a flexible conductor. The bunching process enhances flexibility, tensile strength, and current-carrying capacity, making the conductor suitable for various cable applications.
Stranding
Individual insulated conductors are stranded together according to cable design requirements. This process ensures cable stability, flexibility, and consistent electrical performance while preparing the cable core for subsequent manufacturing stages.
Extrusion
Advanced extrusion equipment applies insulation and outer sheath materials evenly around the conductor and cable core. Depending on product requirements, materials such as PVC, XLPE, LSZH, or rubber compounds are used to provide electrical insulation and environmental protection.
Coiling and Packing
After passing comprehensive quality inspections, finished cables are measured, tested, and packaged according to customer requirements. Products are supplied in coils, reels, drums, or customized packaging to ensure safe transportation and convenient installation.
