N2XB2Y Cable Application

N2XB2Y cable is used for laying in the ground,but also in water, within facilities, in cable canals, in concrete. Used in electric power plants, transformer stations, industrial plants, metropolitan networks and other electric plants. Applied in conditions requiring protection against heavier mechanical damages, but where cables are not exposed to heavier tensile strain.
