(Low Smoke Zero Halogen)
Low smoke zero halogen (LSZH or LSOH) is a material classification used for cable jacketing. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogens when exposed to high sources of heat (ie. flame).
Most network cables are insulated with polyethylene, PVC or Thermoplastic Urethane (TPU) . In fires, a halogen containing plastic material releases hydrogen chloride, a poisonous gas, which forms hydrochloric acid when it comes in contact with water.
Designated Halogen-free cables, on the other hand, does not produce a dangerous gas/acid combination or toxic smoke when exposed to a flame.
Low smoke zero halogen cable reduces the amount of toxic and corrosive gases emitted during combustion. These types of materials are typically used in poorly ventilated areas such as Tunnels, aircrafts or rail cars or crowded places such as airports, railway stations, stadium or residential or commercial towers. Low smoke zero halogen is becoming very popular and in some cases a requirement in instances where the protection of people and equipment from toxic and corrosive gasses is critical.
