Airdac SNE & CNE Concentric Cable

Raw Material Test is the critical first step in manufacturing the Airdac SNE & CNE Concentric Cable. Incoming hard-drawn copper rods undergo detailed chemical composition analysis to confirm high purity and conductivity. Mechanical testing verifies that tensile strength, elongation, and hardness meet SANS 1507-6 requirements. XLPE and polyethylene compounds are tested for thermal stability, UV resistance, and insulation properties. Surface quality inspection and dimensional checks detect any defects or inconsistencies in rod and compound materials. Only raw materials that fully pass every stringent criterion are approved for wire drawing, stranding, and extrusion in the production of the Airdac SNE & CNE Concentric Cable. This thorough incoming inspection guarantees consistent high conductivity, mechanical strength, and long-term durability for reliable aerial service connections.

Process Inspection during manufacturing of the Airdac SNE & CNE Concentric 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 arrangement of phase, neutral, and earth conductors. XLPE insulation and PE sheath extrusion are carefully controlled for thickness uniformity and 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 Airdac SNE & CNE Concentric Cable, delivering a high-quality, tamper-resistant service entrance cable.
