N2XH 1kV LSZH power cable, unarmoured

N2XH 1kV LSZH power cable is designed for fixed power and control applications where protection against mechanical damage is not required. 

These N2XH 1kV LSZH power cables are suitable for installation indoors and outdoors as well as in concrete but not suitable for direct burial in earth or immersion in water.

Ensures increased safety in the case of fire due to the virtual elimination of toxic fumes if burnt. Pronounced advantages when compared to PVC cabling: low fire load, low smoke emission, reduced fire propagation.

Note: low smoke zero halogen / halogen free (LSZH, LSOH, LSHF, OHLS) should not be confused with LSF (low smoke and fume), an in-depth explanation is shown on our Customer Support page.
