Why Should We Use Low Smoke Zero Halogen Cables?
Low Smoke Zero Halogen or low smoke free of halogen (LSZH or LSOHL or SFH or OHLS) is material classification typically used for cable jacketing in the wire and cable industry. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat. Most fiber optic network cables are insulated with polyethylene, PVC or thermoplastic urethane (TPU).
In a fire, a halogen-containing plastic material releases hydrogen chloride, a poisonous gas that forms hydrochloric acid when it comes in contact with water. Designated halogen-free cables, on the other hand, do not produce a dangerous gas/acid combination or toxic smoke when exposed to flame. Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted during combustion.
This type of material is typically used in poorly ventilated areas such as aircraft or rail cars. Low smoke zero halogen is becoming very popular and, in some cases, a requirement where the protection of people and equipment from toxic and corrosive gas is critical. Low Smoke Zero Halogen - a safe alternative: Low Smoke Zero Halogen is actually a very good description of what these cables can do for us. When burning is very little smoke compounds such as polypropylene production, no poisonous gas would like PVC cable.
LSZH cabling or low smoke zero halogen cable is a safe choice area, potential and the potential of people with a fire near the fire. Low Smoke Zero Halogen also complies with the European Union's Restriction of Hazardous Substances (RoHS) directive and similar North American safety and environmental standards.
