Definition and analysis of 5 characteristics of low - smoke zero - halogen cables

Low-smoke zero-halogen cables are a type of special cable. The insulation and outer sheath materials of these cables do not contain halogens such as chlorine and bromine, and they produce very little smoke under fire conditions. Low-smoke zero-halogen cables have some important safety features and are particularly suitable for indoor, enclosed spaces, and places with a large number of people, as well as application areas that are sensitive to the generation of toxic gases and smoke.

The following are the 5 main characteristics of low-smoke zero-halogen cables:

1. Halogen-free materials: The insulation and outer sheath materials used in low-smoke zero-halogen cables do not contain halogens, such as specific types of polyethylene (PE) or polyvinyl chloride (PVC). These materials do not release halogenated gases in a fire, avoiding the generation of toxic gases.2. Low smoke generation: Low-smoke zero-halogen cables produce significantly less smoke under fire conditions. This helps to improve visibility during a fire, reduce the harm of smoke to people, and make it easier for people to evacuate.

3. Fire resistance: Although the main advantage of low-smoke zero-halogen cables is to reduce the generation of toxic gases and smoke, they still have a certain degree of flame retardancy and can suppress the spread of flames in a fire.

4. Indoor applications: Low-smoke zero-halogen cables are commonly used in indoor environments, such as office buildings, residences, commercial buildings, hospitals, schools, etc., especially in places that require high safety and personnel evacuation.

5. Telecommunications and data transmission: Low-smoke zero-halogen cables are also suitable for telecommunications and data transmission, such as Ethernet, telephone systems, and TV signal transmission, to ensure that communication systems can continue to operate during a fire.
