Guide to Low Smoke Zero Halogen cable(LSZH, LSOH, LS0H, LSFH, OHLS)
In the wire and cable industry, fireproof low smoke halogen free cable has become one of the most popular keywords in recent years. The laying of fireproof cables can effectively reduce the probability of fire. The use of Low Smoke Halogen free materials can increase the chances of escape for people in closed areas, because compared with halogen materials, Low Smoke Halogen free materials release less harmful gases when burning and are less harmful to human health.
Low Smoke Zero Halogen Cable (LSZH wire, LSOH cable, LS0H cable, LSFH cable and OHLS cable for short) refers to cables that do not contain halogens (F, Cl, Br, I, At) and do not contain environmental substances such as lead, cadmium, chromium, and mercury. This type of cable is particularly popular in crowded areas such as public places, hospitals, and schools because they can reduce the emission of harmful gases and ensure the safety of personnel when a fire occurs. Low Smoke Halogen free materials are usually used in poorly ventilated environments, such as airplanes, train carriages, or ships. Low Smoke Halogen free materials are also commonly used in the railway industry, where there are high-voltage wires or signal wires that transmit the location of trains under the railway. The use of Low Smoke Halogen free materials can also reduce the accumulation of toxic gases when the cable is damaged by fire or short-circuited.
Low Smoke Halogen free cables are manufactured and tested in strict accordance with international and domestic standards. The specific test details and technical specifications may change. It is recommended to contact TST CABLES engineers directly by email to obtain the latest, most accurate and comprehensive Low Smoke Halogen free cable information. Below, TST CABLES will introduce Low Smoke Zero Halogen cable in detail.
