With the promotion and spread of the concept of green environmental protection in the world, the concept of environmental protection is gradually penetrating into all walks of life. With the gradual use of environmentally friendly products and popular, the wire and cable industry has also begun to pay attention to the development and promotion of environmentally friendly cables.
  
At present, developed countries such as Europe, the United States, Japan and other countries on the use of cable environmental protection requirements are getting higher and higher, has been strictly prohibited to use or import non-environmental protection cable. China also attaches great importance to this field, the relevant laws and regulations explicitly require that in the construction of major projects, the use of non environmental protection cable is strictly prohibited. Previously, Beijing and Shanghai have also banned the use of non-environmentally friendly cables.
  
Traditional cables not only contain heavy metals such as lead, cadmium, and mercury, but also a large number of public hazards such as dioxins, lead, cadmium, and halides will appear in the process of manufacturing, use, and waste treatment; in the event of fire combustion, it will also release A large amount of thick smoke will produce a large amount of corrosive and harmful gases, which will not only pollute the environment, but also cause a large number of casualties. Compared with traditional cables, environmentally friendly cables basically have high flame retardancy, halogen-free, low-carbon, no corrosive gases, high light transmittance, and high protection against ultraviolet rays or water.
  
1, high flame retardancy: environmental protection cable can fully guarantee its high fire requirements of the building, fire, environmental protection cable can not only not easy to burn, but also to prevent the spread of the flame after burning and the expansion of the disaster.
  
2, halogen-free: the use of green insulation layer, sheath and special oxygen barrier material, not only make the environmental protection cable has good electrical properties, physical and mechanical properties, and to ensure that the product does not contain halogen, to solve the combustion of the formation of "secondary pollution", to avoid the traditional PVC wire combustion can produce carcinogenic "dioxin" substances.
  
3, low toxin: environmental protection cable insulation and sheath does not contain lead, cadmium and other harmful to the human body of heavy metals, in the use of environmental protection cable and waste disposal will not pollute the soil, water. And after harsh toxicity experiments, the rats were safe and sound under the prescribed experimental conditions.
  
4, do not produce corrosive gas: the use of environmental pollution-free new special covering materials, so that environmental protection cable in the production, use process and combustion will not produce HCL and other toxic gases, the emission of acid gas is very small, the personnel and equipment, equipment damage is small, more environmental protection characteristics.
  
5, high light transmittance: environmental protection cable burning smoke is extremely thin, is conducive to the evacuation of personnel and fire fighting work. Generally speaking, the light transmittance of environmentally friendly cable products is greater than 40%, which is much higher than the standard that the light transmittance of traditional flame retardant cables is less than 20%.
  
6, high protection of ultraviolet or water: this performance can make the environmental protection cable in use is not easy to be weathered, to a certain extent, slow down the aging speed of environmental protection cable, prolong its service life.
  
In general, environmentally friendly cables are a major trend. In recent years, the sales share of environmentally friendly cable products has expanded dramatically. Due to the characteristics of environmentally friendly cables that are non-toxic and non-polluting to people and the environment, high safety and reliability, and long service life, they will become the mainstream of the future cable market.
