N2XSY MV Copper Cable Product Benefits

1. The cable uses Class 2 stranded copper conductors in compliance with IEC 60228, ensuring excellent conductivity and mechanical strength. XLPE insulation provides low dielectric loss and high thermal stability for continuous operation in medium-voltage networks. The combination of stranded conductors and insulation ensures resistance to vibration, bending, and mechanical stress during installation and service.

2. Flame-retardant design with semi-conducting insulation layers and copper wire screen reduces fire propagation risk. The cable meets IEC 60332-1 standards for flame propagation and maintains integrity during short-circuit events. Optional LSZH (Low Smoke Zero Halogen) outer sheath provides additional safety in enclosed environments by minimizing toxic smoke emission.

3. Designed for installation in cable trays, conduits, ducts, and direct burial. Minimum bending radius is 15 times the overall cable diameter, allowing safe routing through complex industrial and urban network layouts. Stranded conductors and semi-conducting insulation facilitate easy manipulation without compromising electrical performance.

4. Available in 6/10 (12), 12/20 (24), and 18/30 (36) kV ratings. Continuous operation is rated up to 90 °C for XLPE-insulated cables, with short-circuit tolerance up to 250 °C for 5 seconds. Installation temperature down to -5 °C allows use in cold climates without risk of insulation cracking.

5. Conductor sizes range from 16 mm² up to 630 mm², with outer sheathing in PVC, FR-PVC, or LSZH as required. Cable length, color coding, and packaging can be adjusted to meet project-specific specifications. Optional copper tape or wire screen configurations provide enhanced electrical performance and shielding.
