With the promotion and spread of the concept of green environmental protection around the world, the concept of environmental protection is gradually permeating all walks of life. With the gradual use and popular support of environmentally friendly products, the wire and cable industry has begun to attach importance to the development and promotion of environmentally friendly cables.

　　 At present, developed countries such as Europe, the United States, Japan and other countries have higher and higher environmental protection requirements for the cables used, and the use or import of non-environmental cables has been strictly prohibited. my country also attaches great importance to this field, and relevant laws and regulations expressly require that the use of non-environmental protection cables is strictly prohibited in the construction of major projects. 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, mercury, but also a large number of pollutants such as dioxins, lead, cadmium, halides, etc. during the manufacturing, use, and waste treatment processes; they will also be released in case of fire. Emitting a lot of dense smoke will produce a lot of corrosive and harmful gases, which will not only pollute the environment, but also cause a lot of casualties. Compared with traditional cables, environmentally friendly cables and cables basically have high flame retardancy, halogen-free, low-mycin, no corrosive gas, high light transmittance, and high protection against ultraviolet rays or water.

　　1. High flame retardancy: The environmental protection cable can fully guarantee its high building requirements for fire protection. In the event of a fire, the environmental protection cable can not only be difficult to burn, but also prevent the spread of flame and the expansion of disasters after burning.

2. Halogen-free: The use of green environmental protection insulation layer, sheath and special oxygen barrier materials not only make the environmental protection cable have good electrical and physical and mechanical properties, but also ensure that the product is halogen-free and solve the problem of burning "Secondary pollution" avoids carcinogenic "dioxin" substances produced when traditional PVC wires are burnt.

　　3. Low toxin: The insulation and sheath of the environmental protection cable do not contain lead, cadmium and other heavy metals harmful to the human body. When the environmental protection cable is used and discarded, it will not pollute the soil and water sources. And after harsh toxicity tests, the white rats were safe and sound under the specified experimental conditions.

4. No corrosive gas: new special coating materials that are not polluting the environment are used, so that environmentally friendly cables will not produce toxic gases such as HCL during production, use and combustion, and emit very little acid gas, which is harmful to personnel, equipment and instruments. Less damage and more environmentally friendly.

　　5. High light transmittance: The smoke produced when the environmental protection cable burns is extremely thin, which is conducive to the evacuation of personnel and the conduct of fire fighting. Generally speaking, the light transmittance of environmentally friendly cable products is greater than 40%, which is far higher than the standard of less than 20% for traditional flame-retardant cables.

　　6. High protection against ultraviolet or water: This performance can make the environmental protection cable less likely to be weathered in use, slow down the aging speed of the environmental protection cable to a certain extent, and extend its service life.

　　 In general, environmentally friendly cables are a major trend. In recent years, the sales share of environmentally friendly cable products has increased dramatically. As environmentally friendly cables have the characteristics of 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.
