Raw Material Test
Raw material testing for the Steel Tape Armoured Cable STA 0.6/1kV CU/XLPE/STA/PVC ensures full compliance with IEC 60502-1. Copper rods are tested for purity, conductivity, and elongation. XLPE insulation compound is rigorously evaluated for density, melt flow index, antioxidant levels, and crosslinking potential using OIT and DSC analysis. Galvanized steel tapes undergo zinc coating mass, thickness uniformity, tensile strength, and adhesion tests. PVC sheath material is checked for thermal stability and hardness. The step-by-step process includes incoming batch verification, random sampling, chemical composition analysis via spectrometry, mechanical property testing before and after aging, corrosion resistance pre-checks, and final material approval decision. Only qualified materials are released, guaranteeing the Steel Tape Armoured Cable STA 0.6/1kV CU/XLPE/STA/PVC achieves excellent conductivity, insulation integrity, strong armour performance, and long-term durability.
Process inspection
During manufacturing of the Steel Tape Armoured Cable STA 0.6/1kV CU/XLPE/STA/PVC, process inspection maintains strict quality control. Copper conductor stranding is monitored for compactness. XLPE insulation extrusion controls thickness and concentricity with online systems. PVC inner sheath application prepares a smooth surface for armouring. Double steel tape armouring verifies helical overlap, tension balance, and gap-free coverage. Final PVC outer sheath extrusion includes real-time spark testing. Key steps include material pre-drying confirmation, extrusion and armouring parameter logging, intermediate hot set tests for crosslinking degree, armour coverage sampling, defect detection with immediate correction, and controlled cooling. This multi-stage oversight guarantees the Steel Tape Armoured Cable STA 0.6/1kV CU/XLPE/STA/PVC achieves void-free insulation, strong armour adhesion, precise construction, and full IEC 60502-1 compliance throughout production.
Finished Product
The finished Steel Tape Armoured Cable STA 0.6/1kV CU/XLPE/STA/PVC undergoes comprehensive testing.
