Quality Control
4 Strombus Aluminum Conductor Triplex Overhead Service Drop Cable
Raw Material Test
Raw material testing is the first and most critical quality control step for the 4 Strombus Aluminum Conductor Triplex Overhead Service Drop Cable. All incoming aluminum rods and insulation compounds are strictly inspected before entering the production line. The aluminum used for the conductor must meet specified chemical composition requirements, ensuring high electrical conductivity and adequate tensile strength. Spectrometer analysis is performed to verify aluminum purity and to detect any trace elements that could negatively affect performance. Mechanical tests such as tensile strength and elongation are conducted on aluminum rods to confirm their ductility and resistance to breakage during stranding. Surface quality inspection ensures the aluminum rod is free from cracks, inclusions, oxidation, or contamination that could lead to conductor defects.
Process inspection
Process inspection ensures that each production stage of the 4 Strombus Aluminum Conductor Triplex Overhead Service Drop Cable meets defined technical and quality standards. During conductor stranding, inspections focus on strand count, lay length, compactness, and overall conductor diameter. Precision measuring tools are used to verify uniformity and roundness, ensuring optimal electrical performance and mechanical stability. During insulation extrusion, real-time monitoring systems control insulation thickness, concentricity, and surface smoothness. Any deviation from specified tolerances triggers immediate corrective action. Spark testing is continuously applied to detect pinholes or insulation defects, preventing hidden faults in the 4 Strombus Aluminum Conductor Triplex Overhead Service Drop Cable.
Finished Product
Finished product testing validates the overall quality and reliability of the 4 Strombus Aluminum Conductor Triplex Overhead Service Drop Cable before delivery. Electrical tests include conductor resistance measurement to confirm compliance with standard values and ensure efficient current transmission. High-voltage withstand tests verify insulation integrity under specified voltage stress. Mechanical testing evaluates tensile strength, elongation, and adhesion between conductor and insulation. These tests ensure the cable can withstand installation tension and long-term service conditions. Insulation thickness, concentricity, and overall cable dimensions are measured to confirm conformity with design specifications.
