With long-term use of wires and cables, short circuits or fire may occur, which can make the cable combustible, causing fuel fire or damage to equipment. Thus it is necessary for cables to have properties that ensure that it will not spread flames or become flammable over a period of time. This is called the incombustibility of the cable, also known as being flame retardant. If a cable lacks flame retardant properties, fire can cause serious consequences.

The determination of smoke density is another important aspect to evaluate cable combustion characteristics because it concerns the personnel evacuation and if can put out the fire in a short-range. According to the fire department statistics, about 80% of the deaths are caused by the harmful poisoning gas in the fire, the diffuse smoke choking or making the path invisible so that can't escape and then be burned.

Developed countries strictly prohibit the use of non-environmentally friendly cable. Relevant laws and regulations explicitly require that important buildings prohibit the use of polyvinyl chloride wire and cable. The low smoke halogen free cross-linked polyolefin insulated wire and cable must be used, which is what we often call the low smoke halogen free cable, so as to avoid a large amount of smoke and chlorine gas in the event of fire, which may cause casualties. In many important public facilities, such as subways, shopping malls, communications, and other departments.

What is low smoke halogen free cable？

Low smoke halogen free is a material classification for wire sheath in the wire and cable industry. The sheath of low smoke halogen free cable has thermoplasticity or thermosetting property that has low smoke emission when heated and is halogen-free.

The low smoke halogen free materials, on the other hand, do not release hydrogen halide or other acids when they catch fire.

The advantages of low smoke halogen free cable

• Halogen-free: thanks to the use of green eco-friendly insulating layer, sheath, and special oxygen barrier material, it not only has good electrical properties, physical and mechanical properties, but also ensures that the product does not contain halogen.
• Low smoke and low toxicity: the use of new special coating materials that do not pollute the environment can ensure there is no toxic gas during production, use, and combustion, and very little acid gas, so as to reduce damage to personnel and equipment.
• High flame retardancy: the environmentally friendly cable can meet the high building requirements for fire protection. The cable is not easy to burn during a fire and can prevent the spread of flames and the expansion of disasters after combustion.
