What Is The Low Smoke Zero Halogen Cable?


From FiberStore,we will answer to you what is the Low Smoke Zero Halogen Cable. Low Smoke Zero Halogen(LSZH) cable is free of halogen (F, Cl, Br, I, At), lead-free environmental substances such as cadmium, chromium and mercury in the plastic material made ??of combustion does not emit toxic smoke (such as: hydrogen halide,carbon monoxide, carbon dioxide, etc.) environmentally friendly cable. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat.Less toxic and slower to ignite, they are a good choice for many internal installations. This cable may be run through risers directly to a convenient network or splicing closet for interconnection.

Why the halogen is dangerous?

When products containing halogens are burned, they produce very dangerous gasses. Public awareness of these dangers began after several tragic fires claimed the lives of victims who inhaled deadly halogenated fumes.Many organizations, local authorities and governments have undertaken broad initiatives to eliminate the production of halogenated material. In Asia, the United Kingdom and many European communities, the use of wire and cable containing halogens is highly regulated, and in some areas completely prohibited.

Halogenated compounds are normally very stable. When they burn, however, the halogens separate and become highly reactive, forming very toxic, extremely dangerous and corrosive gasses that can significantly damage organic, inorganic and metallic materials. The hydrogen chlorine gas produced from burning PVC, for example, is similar to mustard gas.

Fires involving the combustion of halogenated materials can be devastating. Inhalation of dangerous fumes can cause serious harm or even death to humans. Acid rain and fumes can quickly destroy expensive industrial and computer equipment.

Why use halogen free cable?

Low smoke and halogen free cabling is becoming increasingly necessary to protect against the risk of toxic gas emissions during a fire. Standard RG cables contain halogen insulation. Halogen insulation was first used because it helps prevent cables from fire, but if it does ignite, the resulting fumes are highly toxic and a major risk, both to human life and to circuitry in place: critical, for example, in an aircraft.

Halogen free cables are engineered and designed so that emissions during a fire offer low toxicity and low smoke. This type of cabling is increasingly of relevance in public sector housing and major new developments. It could be increasingly worthwhile and of interest when it comes to elderly housing too, where items such as disabled stair lifts are in use and the risk of additional complications as a result of fire significant.

Halogen free or zero halogen cabling is used in many areas of the cable and wiring industry, including aircraft, rail and construction. Used to protect wiring, it is proven to limit the amount of toxic gas emitted when it comes into contact with heat.
