We supply a comprehensive range of Low Smoke Zero Halogen (LSZH) cables for use in applications where smoke emission and toxic fumes could pose a risk to human health and essential equipment in the event of a fire.
They are therefore often specified indoors, especially in public areas, and in other hazardous environments and poorly ventilated areas.
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.
