SY LSZH NR armoured black control cable is designed for connecting, measuring, checking and control applications where there is a need for armouring. The galvanised steel wire braid (GSWB) provides protection against mechanical damage.
Suitable for use in internal, external or ducted installations, not recommended for immersion in water.
These SY LSZH cables ensure 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.
