Low-smoke, halogen-free flame retardant cables are a new type of environmentally friendly cable with an outer layer of material that can react chemically to slow down the fire when it encounters a fire. Its advantage is that after the fire will not produce the release of toxic and harmful substances, which greatly protects personal safety. Low smoke halogen free cables are referred to as LSZH, LSOH, LS0H, LSFH and OHLS, which are the material classifications of wire sheathing in the wire and cable industry. Low smoke and halogen free wire jacketing is composed of thermoplastic or thermoset materials that have low smoke emission when heated and do not contain halogens.
Most network cable jacketing is composed of polyethylene, polyvinyl chloride, or thermoplastic polyurethane. In the event of a fire, chlorinated plastics release toxic hydrogen chloride, which produces hydrochloric acid when exposed to water. Low-smoke, halogen-free materials do not release hydrogen halide or other acids in the event of a fire.
Low-smoke halogen-free materials reduce the amount of toxic, corrosive gases that are produced when they burn. They are often used in poorly ventilated environments such as airplanes, train cars, or on ships. They are also commonly used in the railroad industry, where there are high voltage lines under the railroad or signal lines that transmit the location of trains. The use of low smoke and halogen free materials also reduces the accumulation of toxic gases when lines are damaged by fires or short circuits.
Like in the railroad industry, automotive, aviation, medical or shipbuilding industry, one of the important needs is to protect personnel and equipment will not come into contact with toxic, corrosive gases, in these occasions will require the use of low-smoke halogen-free materials in the outer layer of the wire and cable.
First, the characteristics of LSZH cable
Low-smoke halogen-free flame retardant cable is a high-tech products, its main feature is the use of low-smoke, halogen-free, flame-retardant materials in the production process, has a good fire performance, can be in the event of a fire to reduce injuries and property damage.
Second, the environmental requirements of LSZH cable
Low-smoke halogen-free cable can work normally under various harsh conditions. Insulation and sheath insulation is good, insulation resistance is large, resistivity between 0.5~35, in line with the QC/T 1847-1999 wire, cable combustion performance requirements.
Third, the performance advantages of LSZH cable
Low-smoke halogen-free cable means that in the wire conductor, there is no halogen, sulfur, nitrogen and other halogenated compounds. It has the advantages of excellent flame retardant properties and insulation properties, good electrical conductivity. Low-smoke halogen-free cable is made of special low-smoke flame-retardant materials to produce wires, which can meet the flame retardant requirements due to its own characteristics, plus some special processing, made of flame-retardant wires, and the safety is also higher. It is also a high-performance energy-saving and environmentally friendly products.

Fourth, the application of LSZH cable
Low-smoke halogen-free flame retardant cables are widely used in oil and gas, nuclear power wind power, aviation, construction, mines, rail transportation, etc., especially in people-intensive places, such as high-rise buildings, hospitals, subways and other places. It is also used in ships, factories and other high-temperature, humid environment.
V. Precautions for the use of low-smoke halogen-free flame retardant cables
Should be installed in a dry environment, you can also use fire-resistant insulation materials, with acetylene-based gases for fire-retardant wires. Keep away from combustible materials in case of fire. In order to prevent injury by electric sparks, it is necessary to pay attention to the inspection to check whether the wire is broken; also pay attention to the protection of the surface of the wire, if there is damage to be replaced in a timely manner.
Six, TSTCABLES low-smoke halogen-free cable and the difference between ordinary cables
TSTCABLES low-smoke halogen-free flame retardant cables are not only environmentally friendly and safe, but also have a high resistance to high temperature, low-smoke halogen-free flame retardant properties, by more and more global users of attention and favor.
Then, the main difference between TSTCABLES low-smoke halogen-free cables and ordinary cables is reflected:
1.LSZH cable material composition:
TSTCABLES low-smoke halogen-free cables use new low-smoke halogen-free materials special materials, these materials in the combustion of smoke produced by less, and does not produce toxic gases. The sheath is composed of thermoplastic or thermoset materials, which do not contain halogens, thus being able to reduce the toxic and corrosive gases produced during combustion.
Ordinary cables (such as BV wire) are usually made of PVC, which is flame retardant but produces smoke and toxic gases when burning.
2.LSZH cable Performance Characteristics:
TSTCABLES low smoke and halogen free cables have superior flame retardant properties and environmental performance. Its flame retardant properties are better than ordinary cables and can better stop the spread of fire in case of fire. In addition, it has better temperature resistance and can remain stable at higher temperatures.
Ordinary cables may not be as good as Low Smoke Halogen Free (LSZH) cables in terms of flame retardancy and temperature resistance.
3.LSZH cable application fields:
TSTCABLES low smoke and halogen-free cables are suitable for places with high requirements for safety and environmental protection, such as oil and gas, nuclear power wind power, aviation, military industry, nuclear power plants, wind power stations, ships, hospitals, high-rise buildings, subways, tunnels and so on. The use of low-smoke halogen-free cables in these places can reduce the emission of toxic gases in case of fire and improve safety.
Ordinary cables are more suitable for general places without special safety and environmental requirements.
4.Methods of recognizing high quality LSZH cables:
The appearance of TSTCABLES low-smoke halogen-free cables is usually smooth, uniform and brightly colored; while the surface of ordinary cables may have impurities, bubbles and other problems. In addition, you can identify the two through the combustion test: low-smoke halogen-free cable combustion produces less smoke and does not produce toxic gases; while ordinary cable combustion will produce smoke and toxic gases.
TSTCABLES low-smoke halogen-free cables and ordinary cables in the material composition, performance characteristics, application areas and identification methods, there are obvious differences. When you choose which cable to use, you should consider according to the actual needs and characteristics of the place.TSTCABLES low-smoke halogen-free cables, safe and environmentally friendly, is to ensure that your electricity stability and safety of the patron saint. We specialize in customizing low smoke halogen free flame retardant cables with the latest technology for various industries all over the world.
