What is LSZH cable and why do we use it?

As LSZH cables produce very little smoke when they come in contact with a flame, they are often used indoors, especially in public areas such as train stations, hospitals, schools, high buildings, and commercial centers where the protection of people and equipment from toxic and corrosive gases is critical. They are also used in poorly ventilated areas and hazardous environments. Data centers contain large amounts of cables and are usually enclosed spaces with cooling systems that can potentially disperse combustion byproducts through a large area. Other materials burning may also contribute greater amounts of dangerous gases which will outweigh the effect of the cables. There have been notable fires where cables burning contributed to corrosion, but in some instances, better fire response techniques could have prevented this damage.

Low Smoke Zero Halogen Material


LSZH materials are used in various applications where smoke emission and toxicity caused by burning of the materials can be a safety hazard, such as in aircraft, trains, ships, data centers, and public spaces.


LSZH materials are made from special polymers that contain no halogenated additives, which are responsible for producing smoke and toxic fumes when the material is burned. Instead, LSZH materials are formulated with fire retardant chemicals that reduce the amount of smoke and toxic gases emitted during a fire.


LSZH materials are preferred in situations where human safety is of utmost importance, as well as in settings where sensitive electronic equipment is present, as smoke and corrosive gases can damage electronic components. LSZH materials are also more environmentally friendly compared to traditional halogenated materials, as they release fewer harmful substances into the environment when burned.

Benefits of Low Smoke Zero Halogen Material

Low Smoke Zero Halogen (LSZH) materials are used in a variety of applications where the release of smoke and harmful gases could pose a threat to human life or equipment. Here are some benefits of this material:


Less Toxicity: LSZH materials contain no halogens, which are known to emit toxic gases when burned. This makes them ideal for use in confined spaces such as aircraft cabins, submarines, and underground tunnels where the accumulation of toxic gases can pose a serious risk to human life.


Increased Safety: In addition to reducing toxicity, LSZH materials also reduce the amount of smoke produced during combustion. This helps to minimize the risk of smoke inhalation, which can cause serious health problems and impair visibility in emergency situations.


Improved Equipment Protection: LSZH materials are also beneficial for protecting equipment in the event of a fire. Since they produce less smoke, they can help to prevent smoke damage to sensitive electronic equipment, which can be costly to replace.


Environmental Friendliness: LSZH materials are also environmentally friendly, as they do not emit toxic gases when burned. This makes them a good choice for use in applications where sustainability and eco-friendliness are important considerations.


Compliance with Regulations: Many industries, including aerospace, transportation, and telecommunications, have regulations that require the use of LSZH materials in certain applications. Choosing LSZH materials can help ensure compliance with these regulations and avoid costly fines or other penalties.
