What Makes LSZH Cables Different?
Unlike PVC cables and those made of other compounds which produce vast amounts of dense black smoke, toxic fumes and acid gas when exposed to fire, LSZH cables produce very low levels of smoke and toxic fume and no acid gases. They are essentially halogen free cables.

Where Are LSZH Cables Used?
LSZH cables are often specified indoors, especially in public areas, and in other hazardous environments and poorly ventilated areas. This includes cars, aircraft, railway carriages and ships. LSZH sheathed cables are commonly used across tunnels and underground rail networks.

LSZH vs LSF Cables
While there is a common misconception that low smoke and fume (LSF) cables and LSZH cables are the same, this is not the case and any confusion between the two could be life-threatening in the event of a fire. Unlike LSZH cables, LSF cables are manufactured using PVC compounds.

In conclusion, LSZH cables are a safer choice for many applications due to their low smoke and zero halogen properties. They are an important consideration for any project where human safety and equipment protection are paramount.
