Quality Control
N2XS2Y Medium Voltage Power Cable(6/10kV, 12/20kV, 18/30kV)
Raw Material Test
Raw material testing for the N2XS2Y Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV) ensures premium quality from the start. Copper conductors are inspected for purity, conductivity, and elongation per IEC standards. XLPE insulation compound undergoes density, melt flow index, antioxidant content, and contamination analysis via OIT, DSC, and microscopy. Screen materials (copper tape/wire) are checked for thickness, adhesion, and resistivity. PE sheath granules face weathering resistance, carbon black dispersion, and environmental stress cracking tests. Water-blocking tapes/swelling powders are verified for expansion rate. Samples endure tensile strength, thermal aging, and partial discharge pre-checks. The step-by-step process: incoming batch verification, sampling protocol, chemical composition analysis via spectrometry, mechanical/electrical property testing (before/after aging), environmental simulation.
Process inspection
During manufacturing of the N2XS2Y Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV), process inspection maintains strict quality. Copper stranding is monitored for compactness and surface quality using laser gauges. Triple extrusion (conductor shield, XLPE insulation, insulation shield) ensures thickness uniformity and concentricity with online X-ray systems. Copper screen application controls tape overlap or wire lay and bonding. PE sheath extrusion includes spark testing and diameter verification. Water-blocking elements are checked for proper placement. Marking permanence and sheath color are inspected. Key steps: material pre-drying confirmation, extrusion/screening parameter logging (temperature, pressure), intermediate hot set tests for crosslinking degree, partial discharge monitoring, defect detection/correction, and post-process cooling control.
Finished Product
The finished N2XS2Y Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV) undergoes rigorous testing for certification. Routine tests include conductor resistance, AC high voltage withstand (up to 3.5U0), partial discharge (≤5pC), screen continuity, and insulation/sheath thickness verification. Type tests cover bending, thermal cycling, impulse withstand, and water penetration. Tan delta measurement assesses dielectric losses. The process steps: sample preparation with terminations, gradual voltage ramp-up, PD monitoring with calibrated systems, timed hold at test voltage, environmental conditioning (heat/water), mechanical load application, post-test electrical/mechanical re-measurement, and visual inspection. Additional checks include capacitance, shrinkage, and marking durability.
Application
N2XS2Y Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV) is ideal for underground power distribution in utilities, industrial parks, renewable energy farms (wind/solar), and urban networks.
