Low Smoke Zero Halogen cable, always short for LSZH cable is a type of cables which jackets and insulation materials are made of special materials that gives off limited smoke and no halogens when come across fire or strong heat. The jackets of LSZH cable consists of thermoplastic or thermoset compounds that produce limited smoke and no halogen when come across high sources of heat, eg. flare. LSZH cable can be also called LSF (low smoke and fume), LSHF (low smoke halogen free), and LSOH (low smoke zero halogen) cable.
Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted during combustion. This type of material is typically used in badly ventilated areas such as planes or railroad cars. Low smoke zero halogen is becoming very popular and, in some cases, a requirement where the protection of men and women and equipment from toxic and corrosive gas is very important. They don’t produce a dangerous gas/acid combination in case of fire. LSZH patch cords are for utilization in patching environments with poor air circulation where personnel and equipment may be exposed to corrosive fumes and toxins during combustion. The cable jacket for these wires is designed to minimize the release of halogen fumes and toxicants into the air, reducing the potential of hazardous contact in occupied spaces. LSZH cables are mainly used in the European countries.
- Used in optical connections in optical communication equipment rooms and optical distribution frames
- Used in optical connections in optical apparatus and equipment
- Used in in pigtails and patch cords
- Ideal for backbone, horizontal, and intrabuilding runs
