Quality Control
RZ1-K XLPE LSZH Flexible Cable
Raw Material Test
Raw material testing for the RZ1-K XLPE LSZH Flexible Cable starts with copper wire inspection for purity, conductivity, and strand flexibility per IEC standards. XLPE insulation compound undergoes melt flow index, density, and antioxidant content analysis using OIT and DSC methods. LSZH sheath material is strictly tested for halogen content (<0.5%), smoke density, and acid gas emission via IEC 60754 protocols. Additives are verified for compatibility and thermal stability. Samples face tensile strength, elongation, and accelerated aging tests. The step-by-step process: incoming batch certification, sampling protocol, chemical composition verification, mechanical property testing (before/after aging), fire performance pre-checks, and material approval. Only compliant materials proceed, guaranteeing the RZ1-K XLPE LSZH Flexible Cable's electrical performance, flexibility, and superior low-smoke zero-halogen safety foundation.
Process inspection
During the manufacturing of the RZ1-K XLPE LSZH Flexible Cable, process inspection ensures consistent quality and flexibility. Class 5 copper stranding is monitored for strand count, lay length, and compactness using optical gauges. XLPE insulation extrusion controls thickness uniformity and concentricity with online laser systems. LSZH sheath extrusion includes real-time spark testing and diameter verification. Core laying and filling are checked for symmetry. Marking permanence and sheath color are inspected. Key steps: material pre-drying confirmation, extrusion parameter logging (temperature, speed), intermediate hot set sampling for crosslinking degree, flexibility checks on samples, defect detection/correction, and cooling control. This rigorous monitoring guarantees the RZ1-K XLPE LSZH Flexible Cable achieves excellent bend radius, void-free insulation, and full compliance with UNE 21123 and LSZH standards.
Finished Product
Completed RZ1-K XLPE LSZH Flexible Cable reels face rigorous factory tests. Mandatory routines: DC resistance, high-potential AC test, insulation thickness, and sheath integrity. Fire tests include smoke production, acidity of gases, and flame propagation. Flexibility and mechanical tests cover repeated bending, torsion, and cold impact. The sequential process: sample conditioning, parameter application (voltage/heat), timed exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional verifications ensure oil immersion performance and marking permanence. Passing all confirms the RZ1-K XLPE LSZH Flexible Cable's fire safety, flexibility, and efficiency for demanding applications.
