Environmentally friendly cables will be the trend of the cable industry
With the development of world economy and technology, the demand for wires and cables is increasing, and their performance requirements are also increasing. Under the new economic situation and technical conditions, the development of the global wire and cable industry is showing new trends. Environmentally friendly cables are gradually entering people's field of vision, and gradually replacing traditional cables to become the focus of global cable development. So, what is an environmentally friendly cable?
1. High flame retardancy
When a fire occurs, traditional cables are extremely easy to burn and release a large amount of harmful gases, while environmentally friendly cables are not only difficult to burn, but also prevent the spread of flames and the expansion of disasters after burning.
Traditional cables generally use halogen-containing PVC to make insulating sheaths or cable filling materials, which are likely to produce carcinogenic "dioxin" substances when burned, while environmentally friendly cables use environmentally friendly insulating layers, sheaths and special oxygen barriers. The material is not only halogen-free, but also has good electrical and physical and mechanical properties.
3. Low toxin
The insulation and sheath of the environmental protection cable do not contain lead, cadmium and other heavy metals that are harmful to the human body. When the environmental protection cable is used and disposed of, it will not pollute the soil and water sources.
4. no corrosive gas
Environmentally friendly cables will not produce toxic gases such as HCL when they are produced, used and burned, and emit very little acid gas, which causes little damage to personnel, equipment and instruments, and shows environmental protection characteristics.
5. High light transmittance
The light transmittance of traditional cables is less than 20%, while the standard for environmental protection cable products is greater than 40%. Therefore, the smoke generated when the environmental protection cable is burned is extremely thin, which is more conducive to the evacuation of personnel and the conduct of fire fighting.
6, high protection
The environmental protection cable is not afraid of the erosion of ultraviolet rays, sand and rain, and can slow down the aging speed of the environmental protection cable to a certain extent and extend its service life
