N2XSY, NA2XSY & NA2XS(F)2Y Medium Voltage XLPE Cables
Product Overview
Engineered for critical power distribution in industrial networks, these DIN VDE 0276-620-compliant MV cables deliver reliable performance across 6/10kV to 18/30kV systems. Featuring XLPE/TR-XLPE insulation and versatile constructions (copper/aluminum conductors, tape/wire screens, armored/unarmored), they excel in direct burial, duct, and harsh environments. Flame-retardant PVC/PE sheaths ensure safety per IEC/EN 60332-1-2.
