What is Low halogen free cable

Low halogen free cable, or LSZH or LS0H cable, is made of a type of plastic that doesn't have any halogens in it. Chlorine and bromine are two halogens that can be very harmful when they catch fire. When it burns, the wire gives off very little smoke and no harmful gases. This makes it easier to breathe and see exits more clearly. The material can help keep fires from spreading by making a barrier. The cable works like any other data or power cable. You can use it with many different types of wire, and it's strong and safe. That is why LSZH cables are widely specified for use in public areas like subways, airports, and tunnels, where human safety is the top priority. They also meet international fire safety standards such as IEC 60332-1 for flame retardancy and IEC 60754 for low corrosive gas emission.

The application of Low halogen free cable

Low-halogen free cable is used in places where safety is very important. They are often used in structures, machinery, and control systems. These wires help keep people safe from fires in crowded places. Because they don't give off as much smoke, they are great for small spaces. They are also used in public places like stations and factories. Several safety rules say that these wires are needed to keep people safer. They are a good choice for modern electrical systems.

メディカル

LSZH cables are very important in healthcare settings because they keep both patients and staff safe. They are important for healthcare facilities' electrical lines and data systems. These cables are needed for scanners and life support systems to work. They protect fragile electronics and cut down on the amount of smoke that comes out when there is a fire. This is very important for patients who can't move quickly. Several hospital rules say that these secure wires must be in certain important places. They are also used in security systems and lights that come on in an emergency.

Power generate station

Using LSZH cables in power plants keeps all on-site workers and facilities safe at all times. These vital cables are properly kept in central control rooms and main switch rooms. If a sudden electrical fault caused a fire, they would help reduce and keep harmful thick smoke down. With this extra valuable time, workers may be able to act and operate more safely. The durable wires also protect expensive industrial machines from corrosive acid gases. They are widely used in key emergency systems and sensitive fire alarms. Strict safety rules in modern power plants often require these essential cables.

Data Center

The main job of LSZH cables in data centers is to protect critical important electronic equipment. You might find a large group of high-performance servers here. Because fires spread so quickly in this dense closed area, it's important to have safe wires. LSZH cables make things easier to see by cutting down on harmful heavy smoke. They also keep dangerous gases from rusting precise machinery. This helps protect core key systems and data when there is a fire. These wires are often used in digital networks and power lines these days. They help make modern data centers fully safer.

What Low halogen free cable can do ?

Low-halogen free cable is safer in case of a fire. Like any other type of cable, they usually carry signals and electricity. But when they are used in a fire, they put out harmful gases and make the smoke less thick. They protect people nearby and slow the spread of the fire. These wires are also better for the environment. There are no harmful substances in them, like lead or mercury. Many of them follow safety rules that are good for the environment. When it comes to wiring, both are safe and good for the environment.

Low smoke & zero halogen release

When LSZH wires burn, they hardly make a thick dark cloud. They don't give off any toxic harmful halogen gases like chlorine does. Because of this, the air is safer to breathe during a fire. Another real benefit is that it protects metal parts and industrial machines from rust. People can see the exits easily and leave quickly. Firefighters can do their jobs better when there isn't as much smoke. These wires mostly produce safe gases and water vapor. Because of this, they are great for essential security systems.

High flame retardancy & high insulation

Low-halogen free cables can withstand heat and fire. They have special chemicals that slow down the spread of fire. They stop the fire from spreading when they get hot. This gives you more time to react and helps you deal with damage. Also, the cables stay strong even when they are in very hot or very cold weather. Even when faced with very difficult problems, they keep the signal or power going. So, they can be trusted in systems that are very important to the mission. They work and are also safe.

Non-toxic & environment-friendly

LSZH cables are safe for both people and the whole environment. They don't have any harsh harmful chemicals, like halogens or heavy metals. When burned, they make gases that are not harmful, like pure water vapor. We make things less harmful to people and the environment. They also make less trash after a fire. Many types of people follow global environmental standards. Some are made from recycled materials to be better for the environment. These wires make it easier to build safe and clean indoor layouts.

What Plastic is preferred to add raw Low halogen Elements

LSZH XLPO

LSZH XLPO is a material made of cross-linked polyolefins. It can withstand a lot of heat and smoke. Even when put under stress, this material keeps its shape. It stops flames from spreading and is also fireproof. When burned, it gives off almost no harmful gas. It is often used in elevators and power cables. These cables need to be safe and last a long time. XLPO is a great choice in these cases.

LSZH TPE/TPU

Both LSZH TPE and TPU are strong and flexible materials. If your cables bend a lot, they might work better with these. These materials can handle wear, grease, and sunlight. They work well even when it's very cold. Newer types are fireproof and meet safety standards. They are important for machines and moving parts. These cables stay flexible and strong even after being used a lot. They do a great job in tough situations.

LSZH XLPE

LSZH XLPE is a type of polyethylene that has been cross-linked. It protects against heat and cold very well. This is a good thing for systems that need a lot of power. It can also handle wetness and harsh conditions very well. When it catches fire, it goes out with very little smoke. It is used in wires that carry data and electricity. Make sure these wires stay level and safe. XLPE gives you both safety and performance.

LSZH PVC

The LSZH PVC that doesn't have halogens is better for the environment. It keeps the flexibility and strength of regular PVC. It lowers the amount of harmful gases that come out and is also fireproof. This is helpful for all kinds of wiring jobs. It is often used in structures and control systems. All of these cables meet the highest safety standards. They are good insulators that last a long time. LSZH PVC is a safe and useful answer.

Designed for safer power distribution

The three main goals of today's power systems are safety, strength, and a longer lifespan. Low-halogen free cables are very important to these systems every day. They are important for the emergency lights and electrical wires. They help lower the amount of smoke during a fire or accident. Because of this, lights and sirens may last longer. It helps people see better, which lets them go to safer places. These lines make sure that power flows safely and steadily to all places. Both the public and businesses trust them.

LSZH vs. PVC: The Fire Safety Showdown

Standard PVC cables may seem cost-effective, but they become a silent threat in a fire. When burned, PVC releases thick, black smoke loaded with hydrogen chloride (HCl) and other toxic halogens. In contrast, Low Smoke Zero Halogen cables are engineered to emit minimal light smoke—less than 30% of PVC’s density—and absolutely zero corrosive gases. Under identical tests, LSZH produces less than 20% of the smoke density of PVC, dramatically boosting visibility for evacuees and reducing the risk of fatal smoke inhalation. Choosing LSZH means choosing survival visibility over poisonous darkness.

International fire safety & environmental requirements

International fire safety

There are a number of international safety standards that low-halogen-free cables must meet. When there is a fire, the amount of smoke and gas that comes out is measured. These tests make sure that there are no halogen acid gases or low smoke levels. These cables are very important for use in public buildings and infrastructure in many places. They also meet all safety standards for flame resistance and safe operation. This makes things safer for workers, customers, and machines. These rules help people use cables safely in many countries today. They make sure that you will be safe in case of a real fire.

Environmental compliance

LSZH materials are not only good for the environment, but they also follow strict rules. There are no toxic halogens or other metals in them. Because of this, they are less likely to hurt people when they are used, handled, or recycled. When they catch fire, they let off gases and vapors that aren't too harmful. If this is kept up, people and rescuers will be able to breathe more easily. They also help keep machines, walls, and metal parts safe from damage. These wires encourage building practices that are safe, clean, and good for the environment. They are better for modern projects that care about the environment.
