Low Smoke Zero Halogen

Low Smoke Zero Halogen

Low smoke zero halogen (LSZH or LSOH) is a type of cable jacketing used in the manufacture of industrial and network cabling. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogens when exposed to high sources of heat.ref|mssfibre.com.au

Most network cables are insulated with PVC plastic. In fires, this plastic material releases hydrogen chloride, a poisonous gas, which forms caustic hydrochloric acid when it comes in contact with water. Halogen-free cable, on the other hand, is made of a different material called polypropylene, which doesn't produce a dangerous gas/acid combination.

Low smoke zero halogen cable reduces the amount of toxic and corrosive gases emitted during combustion. Typically used in poorly ventilated areas, low smoke zero halogen is becoming very popular where the protection of people and equipment from toxic and corrosive gasses is critical.
