N2XH-J and N2XH-O cables (N2XH-J with a protective conductor and N2XH-O without a protective conductor) are widely used European power cables used for electricity supply for fixed installations with a voltage rating of 600/1000V in public buildings. Their flame-retardant non-corrosive (FRNC) outersheath makes them suitable for use where smoke and corrosive gases would pose a risk to human life and sensitive equipment in the event of a fire.
These cables are suitable for use in dry and damp environments, on or under plaster, on cable trays, in walls, masonry and in concrete. The N2XH cable is not suitable for direct burial without external protection against mechanical stress or water.
