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.

| Technical – N2XH 1kV LSZH power | |
|---|---|
| conductor make-up: | up to 16.0mm² = class 1 (solid) |
| 25.0mm² and above = class 2 (non-flexible stranded) | |
| – see Stranding/Resistance page | |
| bend radius: | 12 x overall diameter |
| voltage rating: | 600/1000V operating , 4000V test |
| current rating: | as per N2XY and N2XH chart, see Current Ratings page |
| temperature range: | -40°C to +90°C operating, -5°C to +90°C during installation |
| construction: | generally according to DIN VDE 0276 part 604 |
| smoke emission: | according to EN 50268-1+2, IEC 61034-1+2 |
| flame retardant: | according to EN 50266-2, IEC 60332-3 |
| acid gas emission: | according to EN 50267-2-1, IEC 60754-2 |
| core identification: | single core = black insulation (N2XH-O) or green/yellow (N2XH-J) |
