NA2XSY Aluminum XLPE LSZH Cable
Raw Material Test
For the NA2XSY Aluminum XLPE LSZH Cable, raw material testing begins with aluminum conductor certification for electrical grade and elongation. XLPE granules are analyzed for antioxidant levels, crosslinking potential, and impurities via TGA and microscopy. LSZH compounds undergo strict halogen-free verification (chlorine/bromine <50ppm), smoke opacity, and acid gas tests. The structured process: receipt inspection, random sampling, physical/mechanical testing, chemical composition confirmation using advanced spectroscopy, accelerated aging trials, and release decision. This ensures premium inputs, establishing the foundation for the NA2XSY Aluminum XLPE LSZH Cable's conductivity, dielectric strength, and superior fire performance.
Process inspection
Process inspection in NA2XSY Aluminum XLPE LSZH Cable production involves continuous quality checks. Conductor forming monitors strand uniformity and surface defects. XLPE insulation extrusion ensures even coverage with real-time thickness gauges. LSZH sheath application includes online spark testing and diameter control. Core assembly verifies twisting and bedding. Printing durability is inspected. Critical steps: pre-extrusion compound verification, line parameter stabilization, capacitance monitoring for eccentricity, gel fraction sampling, and immediate corrective actions. This ensures the NA2XSY Aluminum XLPE LSZH Cable maintains precise dimensions, reliable insulation, and compliance with LSZH and IEC requirements.
Finished Product
Completed NA2XSY Aluminum XLPE LSZH Cable reels are rigorously tested. Mandatory routines: DC resistance, high-potential AC test, insulation resistance in water, and thickness verification. Fire tests include smoke density (IEC 61034), acid gas emission (IEC 60754), and flame propagation. Mechanical tests cover impact and cold bend. The sequential process: sample conditioning, parameter application (voltage/heat), timed exposure, recovery inspection, re-measurement of properties, and documentation. Additional checks ensure marking legibility and flexibility. Passing all confirms the NA2XSY Aluminum XLPE LSZH Cable's low-emission safety, durability, and efficiency for low-voltage systems.
