Materials

• Low-smoke Halogen-free Cables: The insulating layer and sheath are made of halogen-free materials such as polyolefin, and metal hydroxides and other flame retardants are added. They will not produce toxic gases such as hydrogen halide when burning.
• Conventional Cables: The insulating layer and sheath mostly use halogen-containing materials such as polyvinyl chloride (PVC), which will release a large amount of toxic and harmful hydrogen halide gases when burning.

Performance

• Low-smoke Halogen-free Cables: They have low-smoke performance, producing less smoke and high light transmittance when burning, which is convenient for people to escape in case of fire and for firefighters to carry out rescue work. Their flame retardancy is good, which can effectively prevent the spread of fire.
• Conventional Cables: They will produce a large amount of thick smoke when burning, reducing the visibility at the fire scene and hindering the evacuation of people and rescue work. Their flame retardancy varies depending on the specific materials and processes, and the flame retardant effect of some conventional cables may be worse than that of low-smoke halogen-free cables.

Environmental Friendliness

• Low-smoke Halogen-free Cables: In the process of production, use and waste treatment, they cause less pollution to the environment, meet environmental protection requirements, and can reduce pollution to soil, water sources, etc.
• Conventional Cables: Halogen-containing materials will release harmful substances in the process of production and combustion, causing harm to the environment and human health. They are also difficult to degrade after being discarded, causing certain environmental pollution.

Safety

• Low-smoke Halogen-free Cables: They do not contain halogens and do not produce toxic gases when burning, reducing harm to the human body and the risk of people being poisoned by inhaling toxic gases in case of fire.
• Conventional Cables: The toxic gases produced by burning may cause serious harm to the human body and even endanger life. The safety risk is relatively high when they are used in crowded places or important facilities.

Application Scenarios

• Low-smoke Halogen-free Cables: They are suitable for places with high requirements for safety and environmental protection, such as hospitals, schools, subways, airports, high-rise buildings, data centers and other crowded or important places.
• Conventional Cables: They are widely used in general power transmission and electrical equipment connection occasions, such as ordinary residential buildings, industrial plants and other places with relatively low requirements for environmental protection and safety.

Price

• Low-smoke Halogen-free Cables: Due to the use of special materials and production processes, their prices are usually higher than those of conventional cables.
• Conventional Cables: The prices are relatively low, and they have a certain cost advantage when the basic use requirements are met.
