N2XSY Medium Voltage Power Cable(6/10kV, 12/20kV, 18/30kV)
N2XSY are medium voltage power cables with copper conductors and cross-linked polyethylene (XLPE) insulation, designed according to DIN VDE 0276-620 standards. Constructed with high-purity copper conductors, thermosetting XLPE insulation, metallic screen (copper tape or wires), and tough PVC outer sheath, it meets IEC 60502-2 requirements. The screen ensures electromagnetic compatibility and fault protection. Low tan delta, high breakdown strength, and excellent thermal endurance minimize losses and support overloads. PVC sheath provides solid mechanical and moisture protection for fixed installations. Optional longitudinal water-blocking improves performance in damp areas. Flame-retardant and easy to handle, the N2XSY Medium Voltage Power Cable is favored for power grids, manufacturing plants, commercial developments, and renewable energy sites demanding robust single-core medium voltage cabling with proven durability and cost efficiency in buried or tray installations worldwide.

N2XSY Medium Voltage Power Cable(6/10kV, 12/20kV, 18/30kV)
Raw Material Test
For the N2XSY Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV), raw material testing commences with copper certification for oxygen content and elongation. XLPE granules are tested for crosslinking agent, thermal stability, and impurities via hot set pre-checks and TGA. Metallic screen materials undergo thickness uniformity and conductivity verification. PVC compound faces Congo red testing, volume resistivity, and migration analysis. Water-blocking components are checked for expansion rate. The structured process: receipt documentation review, random sampling, physical/mechanical testing (tensile, yield), chemical spectroscopy confirmation, accelerated aging trials, and material release decision. This comprehensive evaluation secures premium inputs, forming the base for the N2XSY Medium Voltage Power Cable's dielectric performance, screening reliability, PVC sheath strength, and exceptional longevity in medium voltage systems.
Process inspection
Process inspection during N2XSY Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV) manufacturing involves real-time quality checks. Conductor stranding monitors surface defects and compactness. Triple co-extrusion ensures void-free bonding of shields and insulation with capacitance gauges. Screen application controls coverage and tension balance. PVC sheath extrusion includes online spark testing and ovality control. Water-blocking placement is verified. Critical steps: pre-extrusion compound dryness check, parameter stabilization, real-time eccentricity monitoring, gel fraction sampling, partial discharge intermediate scanning, and defect removal protocols. This multi-stage assurance maintains the N2XSY Medium Voltage Power Cable's precise geometry, reliable metallic screening, strong PVC sheath adhesion, and IEC 60502-2 compliance throughout production.
Finished Product
Completed N2XSY Medium Voltage Power Cable (6/10kV, 12/20kV, 18/30kV) reels face strict factory acceptance tests. Mandatory routines: DC resistance, high-potential AC test, partial discharge measurement (≤5pC), screen resistance, and thickness checks. Extended tests include switching impulse, long-duration voltage, heat cycling, and water tightness. Tan delta and capacitance assessments follow. The sequential process: sample conditioning, voltage ramp application, PD monitoring, timed exposure to heat/water, recovery phase inspection, property re-measurement, and documentation. Additional verifications cover bending radius and marking permanence. Passing all confirms the N2XSY Medium Voltage Power Cable's electrical uniformity, screening effectiveness, mechanical endurance, and suitability for critical medium voltage underground and tray installations.
