What are the advantages of low-smoke halogen-free cable?

Low-smoke halogen-free cable is the type cable with insulating materials halogen substances that do not release halogen-containing gases in the event of combustion and have a low concentration of smoke. Many cables are currently clad with polyethylene, polyvinyl chloride or thermoplastic polyurethane. If on fire, chlorine-containing plastics release toxic hydrogen chloride, which produces hydrochloric acid if it encounters water. Low-smoke halogen-free materials do not release hydrogen halide or other acids in the event of a fire.
The advantages of low smoke halogen-free cable
1. Halogen-free
The use of low-carbon environmentally friendly cable sheath, not only has good electrical properties and physical and physical properties, but also to ensure that the product is halogen-free, to avoid the incineration of the "secondary pollution", eliminating the traditional PVC cable ignited when the production of harmful chemicals.
2. High flame retardant grade
For fire safety provisions of high engineering and construction regulations, in a fire accident, the cable is not easy to ignite, and can prevent the spread of flame and damage to the expansion of the combustion.
3. Will not cause corrosion to the vapor
Selection of raw materials with zero pollution to the natural environment, not easy to produce HCL and other vapors throughout the production process and ignition process, the discharge of acid gas is very little, less harmful to workers and mechanical equipment, more environmentally friendly.
4. Moisture-proof and UV blocking
Adopt green environmental protection material to ensure low water absorption. Unique light stabilizer makes the goods have good UV blocking effect. It ensures the safety factor used in such commodities and increases the service life.
5. High light transmission rate
The smoke produced when the cable is ignited is thin, which is favorable to the fire evacuation and fire fighting of employees.
Low-smoke and halogen-free materials reduce the amount of toxic, corrosive gases produced when they burn. They are often used in poorly ventilated environments such as airplanes, train cars or on ships. They are also commonly used in the railroad industry, where there are high voltage lines under the railroad or signal lines that transmit the location of trains. The use of low smoke and halogen free materials also reduces the accumulation of toxic gases when lines are damaged by fires or short circuits. As in the railroad industry or shipbuilding industry, one of the important needs is to protect personnel and equipment from exposure to toxic, corrosive gases, in these occasions will require the use of low-smoke halogen-free materials in the outer layer of the wire and cable.
