In modern electrical systems, fire protection and environmental sustainability have become major concerns, especially when large amounts of wires and cables are involved. The solution to these issues is the use of low-smoke zero-halogen（LSZH）compounds, which are designed to reduce the risks associated with traditional halogen cables. These materials are particularly suitable for cable sheathing, providing a safer and more environmentally friendly alternative by emitting less smoke and no harmful halogens during combustion.
LSZH compounds are materials that do not contain halogens such as chlorine, bromine or fluorine, and include categories such as LSOH or LS0H or LSFH or OHLS or ZHFR. Traditional halogen materials, such as PVC, contain elements such as chlorine and bromine, which release toxic and corrosive gases when burned. These gases pose a significant risk to human health and can seriously damage sensitive electronic equipment.
On the other hand, LSZH compounds are halogen-free, which means that they do not produce these toxic gases when exposed to fire. Therefore, low-smoke zero-halogen cables are widely considered safer, especially in environments with a large number of people such as indoors and public places.
One of the most important properties of LSZH materials is that they contain no halogen compounds. Unlike conventional halogen cables that release corrosive gases such as hydrogen chloride, halogen-free LSZH cables release virtually no harmful substances, reducing the overall risk to human health and infrastructure.
During a fire, reducing smoke emissions is critical for visibility and the safety of people who need to evacuate a building or area. LSZH cable jackets minimize the dense black smoke typically associated with burning halogen materials, making it easier for people to escape and for firefighters to control the situation.
LSZH composites have excellent flame-retardant properties that help slow the spread of fire. This property is particularly important in confined spaces such as subway tunnels, aircraft, and buildings. Using LSZH materials in cable jacket materials ensures that flames do not spread along the cable, reducing the overall risk of fire.
Reduced smoke and toxicity are another important property of LSZH composites. When conventional halogen materials burn, they release toxic fumes that are not only harmful to breathe but also corrosive to equipment. In contrast, smokeless halogen LSZH cables minimize both of these hazards, providing a safer environment in the event of a fire.
Since LSZH compounds do not contain harmful halogens, they are more environmentally friendly. When halogen materials burn, they release pollutants into the atmosphere, which can cause long-term environmental damage. Halogen-free LSZH materials avoid this, making them a more sustainable choice.In addition, the LSZH particles used in the manufacturing process can often be recycled, further contributing to its eco-benefits.

| Tear resistance | Electric vehicles and automobiles |
In the construction industry, fire safety is a top priority, especially in high-rise buildings, public facilities, and other buildings with high occupancy rates. LSZH cables are often used in these environments because they provide enhanced fire safety without compromising performance. Halogen LSZH cables are particularly useful in critical systems, such as emergency lighting, fire alarm systems, and elevator control systems, where reliable fire protection is essential.
Because of the limited space in transportation systems, whether in airplanes, trains, buses or ships, LSZH cable sheathing is becoming the material of choice for wiring systems. In these environments, low-smoke halogen-free materials not only provide fire safety, but also reduce the generation of toxic gases, thereby ensuring the safety of passengers and crew.
In data centers and telecommunications facilities, the protection of sensitive electronic equipment is critical. Fires in these environments can cause serious operational downtime and even loss of valuable data. LSZH cable sheathing is widely used in these environments to protect equipment and personnel.
The industrial and marine sectors are particularly susceptible to fire hazards due to the harsh working conditions of such environments. In these environments, LSZH cable sheathing is essential to minimize the risk of fire. Industries such as oil and gas, chemical processing and marine transportation often rely on LSZH materials to ensure fire safety and reduce the environmental impact of potential fires.
As people's attention to electric vehicles (EVs) continues to increase, the demand for safer and more sustainable electrical systems is also increasing. LSZH compounds are increasingly used in the wiring systems of electric vehicles to minimize fire risks and reduce the release of harmful gases in the event of an accident. This ensures passenger safety while complying with strict environmental regulations.
As industries continue to prioritize safety and sustainability, demand for LSZH cable jacketing materials is expected to grow. These compounds provide a reliable solution for minimizing fire hazards, ensuring a safer environment, and reducing the long-term environmental footprint of electrical systems.
