Premium Copper Contact Wire Manufactured by Weiguang Cable

Weiguang copper contact wires undergo a meticulous production process to ensure durability and conductivity. Here’s a glimpse into their creation:

Initial Drawing: High-purity copper rods are drawn through diamond-coated dies, reducing their diameter in stages. This cold-working process enhances tensile strength while maintaining conductivity.

Eddy Current Testing: Post-initial drawing, wires pass through an eddy current tester. This non-destructive method detects surface flaws like cracks or impurities using electromagnetic fields, ensuring only defect-free wires proceed.

Final Drawing: Approved wires undergo precision drawing to achieve exact dimensions. This step refines the wire’s surface finish and mechanical properties, critical for consistent performance under high stress.

Quality Control: Rigorous checks follow, including diameter measurement, tensile strength tests, and conductivity verification. Surface inspections ensure smoothness, minimizing wear on overhead line systems.

Packing: Finished wires are wrapped in moisture-resistant materials and packed in steel-wooden drums. Secure packaging safeguards against damage during transit.

Each phase blends advanced technology with stringent checks, guaranteeing copper contact wires meet global standards for safety and efficiency. From raw material to final spool, precision is paramount—ensuring seamless power transmission across railways worldwide.
