Raw Material Test
Raw Material Test is the critical first step in manufacturing the Copper Concentric Service Cable. Incoming hard-drawn copper rods undergo detailed chemical composition analysis to confirm high purity and conductivity. Mechanical testing verifies tensile strength, elongation, and hardness meet international standards. XLPE and polyethylene compounds are rigorously tested for thermal stability, dielectric strength, UV resistance, and moisture resistance. Surface quality inspection and dimensional measurements detect any defects or inconsistencies in rod and compound materials. Metallographic examination confirms uniform grain structure in copper. Only raw materials that fully pass every stringent criterion are approved for wire drawing, stranding, and extrusion in the production of the Copper Concentric Service Cable. This thorough incoming inspection guarantees consistent high conductivity, mechanical strength, and long-term durability for low-voltage service entrance applications.
Process inspection
Process Inspection during manufacturing of the Copper Concentric Service Cable maintains precise control at every stage. After drawing copper wires to exact diameters, continuous monitoring verifies dimensional tolerances and surface quality. The concentric stranding process employs real-time tension control and lay length verification to achieve uniform round configuration with phase and neutral conductors. XLPE insulation and polyethylene sheath extrusion are carefully controlled for thickness uniformity and strong adhesion. Online diameter measurement systems and frequent visual checks prevent defects such as uneven lay or insulation imperfections. Key process parameters including temperature and speed are strictly logged. Mid-process sampling includes partial electrical and mechanical tests. Any deviation triggers immediate corrective action. These rigorous in-process controls safeguard the structural integrity and electrical properties of the Copper Concentric Service Cable, delivering a high-quality, flexible low-voltage cable ready for service entrance use.
Finished Product
Finished Product testing ensures every reel of Copper Concentric Service Cable meets the highest quality standards. Comprehensive dimensional verification confirms overall round configuration, conductor alignment, and sheath thickness. DC resistance, high-voltage, and insulation resistance tests validate electrical performance. Mechanical tests measure tensile strength and elongation. Full visual and tactile inspections check for surface defects or sheath imperfections. All examinations follow applicable international standards with detailed records for full traceability. Packaging and marking accuracy are also verified. Only the Copper Concentric Service Cable that successfully passes 100% of these final inspections receives approval for shipment. This rigorous final quality gate assures customers of outstanding conductivity, mechanical strength, weather resistance, and reliable performance in low-voltage service entrance applications.
