Quality Control
NYBY 0.6/1kV Low Voltage Power Cable
Raw Material Test
For the NYBY 0.6/1kV Low Voltage Power Cable, raw material testing starts with copper certification for oxygen-free grade and mechanical properties. PVC compounds undergo viscosity, thermal stability, and migration analysis. Steel wires are checked for galvanisation mass, diameter tolerance, and breaking load. Fillers face moisture and compatibility tests. The structured process: receipt documentation review, random sampling, physical/mechanical testing (tensile, elongation), chemical verification using spectroscopy, accelerated aging/corrosion trials, and material release decision. This ensures defect-free inputs, providing the base for the NYBY 0.6/1kV Low Voltage Power Cable's superior conductivity, insulation quality, robust armour performance, and environmental resistance in low-voltage underground applications.
Process inspection
Process inspection in NYBY 0.6/1kV Low Voltage Power Cable production involves real-time quality assurance. Copper conductor forming monitors strand uniformity and surface smoothness. PVC insulation extrusion ensures even coverage with thickness gauges. Assembly stages check core positioning and filler distribution. Steel wire armouring controls helical lay, tension balance, and overlap. Sheath extrusion includes online spark testing and diameter verification. Critical steps: pre-extrusion compound verification, parameter stabilisation, real-time dimension scanning, armour wire coverage measurement, sampling for uniformity, and defect removal protocols. This multi-stage control maintains the NYBY 0.6/1kV Low Voltage Power Cable's structural precision, armour reliability, and VDE/IEC compliance throughout manufacturing.
Finished Product
Completed NYBY 0.6/1kV Low Voltage Power Cable reels face rigorous tests. Key routines: DC resistance, high-potential AC test, insulation thickness, sheath integrity, and armour continuity. Mechanical endurance via impact, crushing, and pulling tests. Flame propagation and heat shock evaluations follow. The sequential process: conditioning, voltage/mechanical load application, timed exposure monitoring, recovery inspection, property re-measurement, and documentation. Additional checks cover ovality and weight. Passing all confirms the NYBY 0.6/1kV Low Voltage Power Cable's mechanical strength, electrical reliability, moisture protection, and suitability for direct burial low-voltage networks in demanding conditions.
