NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable
Raw Material Test
For the NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable, raw material testing begins with aluminium ingot/rod certification for alloy and conductivity. PVC resins undergo viscosity, K-value, and monomer analysis. Stabilizers/plasticizers are quantified for migration risk. Earth core coloring (NAYY-J) faces light fastness tests. Compounds are tested for dielectric strength and thermal endurance. The structured process: receipt documentation review, random sampling, physical/mechanical testing, chemical verification, accelerated aging trials, and material release. This rigorous evaluation secures defect-free inputs, establishing the foundation for the NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable's conductivity, insulation reliability, and environmental performance in low-voltage fixed installations.
Process inspection
Process inspection in NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable production involves multi-point checks. Aluminium forming monitors strand compactness and defects. Core insulation extrusion ensures adhesion with thickness gauges. Assembly stages verify core arrangement (earth inclusion for NAYY-J) and filler. Outer sheath extrusion includes spark testing and eccentricity measurement. Printing durability and color consistency are assessed. Critical steps: pre-extrusion mixing verification, line speed/temperature control, in-process voltage testing, cross-section sampling, core identification checks, and defect removal. This ensures the NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable achieves uniform construction, reliable insulation, and full VDE compliance.
Finished Product
Completed NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable is strictly tested. Key routines: DC resistance, AC voltage test, thickness checks, continuity (earth for NAYY-J), and identification verification. Flame test (vertical), cold bend, and impact confirm properties. Long-duration heat/moisture tests assess aging. The sequential process: reel sampling, test setup with bath/oven, parameter application, timed exposure, recovery inspection, re-measurement, and documentation. Additional checks cover diameter and weight. Passing all verifies the NAYY-J and NAYY-O 0.6/1kV Low Voltage Power Cable's safety, robustness, and efficiency for low-voltage transmission.
