Description

N2XSY Medium Voltage Cables (6/10kV) – XLPE Insulated, VDE 0276-620 | Copper Screen & PVC Sheath-Picture1

N2XSY 6/10kV Medium Voltage Cables

Product Overview:

Engineered for reliable power distribution in demanding industrial environments, the N2XSY 6/10kV cable delivers superior performance under DIN VDE 0276-620, HD 620, and EN 60228 standards. Featuring XLPE insulation, copper screening, and flame-retardant PVC sheath, this cable is designed for direct burial, duct installation, and industrial plant applications where safety and durability are critical.

Key Features & Benefits

  • Robust Construction: XLPE insulation + dual semi-conductive layers ensure electrical integrity

  • Flame Retardancy: Complies with IEC/EN 60332-1-2 for enhanced fire safety

  • Wide Temp Range: -20°C to +70°C (operational), -5°C to +70°C (flexed)

  • Short-Circuit Resilience: Withstands 250°C conductor temperatures (1-sec fault)

  • Easy Installation: 15×OD bending radius for confined spaces

  • Certified Reliability: CE and ISO 9001 certified
