Quality Control
2 Chow Aluminum Conductor Duplex Overhead Service Drop Cable
Raw Material Test
The Raw Material Test is the first quality control step for the 2 Chow Aluminum Conductor Duplex Overhead Service Drop Cable. Incoming aluminum rods are tested for chemical composition, electrical conductivity, tensile strength, and elongation to ensure compliance with specification requirements. Surface quality and dimensional accuracy are inspected to prevent defects during wire drawing. Each batch of aluminum material is labeled and traceable throughout the manufacturing process. Only materials that meet defined electrical and mechanical criteria are released for production, ensuring the finished 2 Chow Aluminum Conductor Duplex Overhead Service Drop Cable delivers consistent performance and long-term reliability.
Process inspection
Process Inspection ensures stable manufacturing quality of the 2 Chow Aluminum Conductor Duplex Overhead Service Drop Cable. During wire drawing, conductor diameter, surface finish, and mechanical consistency are continuously monitored. In the stranding process, controlled tension and precise lay length are applied to achieve proper flexibility and conductor balance. In-process inspections verify strand alignment, compactness, and roundness. These systematic checks ensure the cable meets design specifications for electrical performance and mechanical durability.
Finished Product
The Finished Product Test confirms the final quality of the 2 Chow Aluminum Conductor Duplex Overhead Service Drop Cable.
