The use of LSZH cables has become increasingly popular in recent years due to the growing awareness of the health and safety risks associated with PVC cables. In addition, many countries and regions have enacted legislation mandating the use of LSZH cables in certain applications, such as in public buildings and transportation systems.
LSZH cables are typically made from materials such as polyolefin, fluoropolymer, or silicone rubber, which have low smoke and toxicity properties. They are also designed to withstand high temperatures and have excellent flame retardant properties, making them suitable for use in harsh environments where fire safety is a priority.
Differences between LSZH cable and traditional cables
The main differences between LSZH (Low Smoke Zero Halogen) cables and traditional cables are their material composition and their fire safety properties.
1.Material Composition:
- a.Traditional cables are typically made from PVC (polyvinyl chloride) or other halogen-containing materials, which emit toxic smoke and gases when burned.
- b.LSZH cables are made from materials that contain little or no halogens, such as polyolefin, fluoropolymer, or silicone rubber. These materials have low smoke and toxicity properties, reducing the risk of harm to people and equipment in the event of a fire.
2.Fire Safety Properties:
- a.Traditional cables are highly flammable and can easily ignite in the event of a fire, which can spread quickly and release toxic smoke and gases.
- b.LSZH cables are designed to be flame retardant and self-extinguishing, meaning they are less likely to catch fire and, if they do, the flames will not spread as quickly. In addition, they produce significantly less smoke and toxic gases when burned, reducing the risk of harm to people and equipment.
So, LSZH cables are considered safer and more environmentally friendly than traditional cables, particularly in enclosed spaces such as buildings, aircraft, and ships. However, they are generally more expensive than traditional cables due to their specialized materials and manufacturing processes.
Different types of LSZH cable available in the market
There are several different types of LSZH (Low Smoke Zero Halogen) cables available in the market, each designed for specific applications and environments. Here are some of the most common types:
1.LSZH Power Cables:
These cables are used to transmit power in low voltage applications, such as in buildings, data centers, and industrial equipment.
2.LSZH Control Cables:

3.LSZH Communication Cables:
These cables are used to transmit data and telecommunications signals, such as in local area networks (LANs), wide area networks (WANs), and fiber optic networks.
4.LSZH Coaxial Cables:
These cables are used to transmit high-frequency signals, such as in cable television (CATV) systems and radio frequency (RF) applications.
5.LSZH Fiber Optic Cables:
These cables are used to transmit optical signals, such as in high-speed internet connections, telecommunications networks, and medical equipment.
6.LSZH Instrumentation Cables:
These cables are used to transmit low voltage signals, such as in measurement and control systems, process control, and automation.
7.LSZH Fire Alarm Cables:
These cables are designed for fire alarm and emergency systems, providing critical communication during emergencies while minimizing the risk of toxic smoke and gases.
LSZH cables offer a wide range of options for various applications, providing both safety and performance benefits in environments where fire safety is a priority.
How to choose the right LSZH cable for your needs？
LSZH (Low Smoke Zero Halogen) cables are designed for use in environments where the release of toxic and corrosive gases from traditional cables could pose a risk to human life or critical equipment in the event of a fire. Here are some factors to consider when choosing the right LSZH cable for your needs:
1.Application: LSZH cables are used in a variety of applications such as data centers, public transportation, and military installations. The specific application will determine the type of LSZH cable required, for example, fiber optic or copper cables.
2.Temperature range: Ensure that the LSZH cable you choose is rated for the temperature range that it will be exposed to in your environment. LSZH cables have a lower temperature rating than regular PVC cables, so it is important to choose one that is rated for the specific temperature range of your application.
3.Cable diameter: The diameter of the cable should be chosen based on the specific installation requirements of the application. LSZH cables are available in various diameters, so it is important to select the right size to ensure proper installation and avoid any damage to the cable.
4.Cable length: Calculate the length of cable required for the installation, and ensure that the cable you select is available in the required length.
5.Certification: Choose an LSZH cable that has been certified by industry standards bodies to ensure that it meets the required safety and performance standards for your application.
6.Manufacturer: Select a reputable manufacturer that has a track record of producing high-quality LSZH cables.
By considering these factors, you can choose the right LSZH cable for your needs and ensure that your installation is safe and reliable.
Areas where LSZH cable is commonly used?
LSZH (Low Smoke Zero Halogen) cables are commonly used in environments where the release of toxic and corrosive gases from traditional cables could pose a risk to human life or critical equipment in the event of a fire. Here are some of the areas where LSZH cables are commonly used:
1.Data centers:
LSZH cables are used extensively in data centers where large amounts of cables are present in a confined space. In the event of a fire, LSZH cables release very low levels of smoke and do not produce any toxic fumes, which reduces the risk of injury to personnel and damage to equipment.
2.Public transportation:
LSZH cables are used in public transportation systems such as trains, buses, and airplanes where passengers and crew are in close proximity to cables. LSZH cables help to reduce the spread of toxic fumes in the event of a fire, which is especially important in enclosed spaces.
3.Military installations:
LSZH cables are used in military installations where the release of toxic fumes could affect personnel and equipment in the event of a fire. LSZH cables help to maintain the integrity of communication systems in critical situations.
4.Hospitals:
LSZH cables are used in hospitals where the release of toxic fumes could affect the health of patients and medical staff in the event of a fire. LSZH cables help to reduce the spread of toxic fumes and smoke in critical areas such as operating rooms and intensive care units.
5.Commercial buildings:
LSZH cables are used in commercial buildings where the release of toxic fumes could pose a risk to occupants and damage critical equipment. LSZH cables help to maintain the safety and reliability of building systems such as fire alarms, security systems, and communication systems.
LSZH cables are used in a wide range of applications where safety and reliability are critical factors.
