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 and popularity of environmental protection products, the wire and cable industry also began to pay attention to the research and development and promotion of environmental protection cables.
At present, developed countries such as Europe, the United States, Japan and other countries have higher and higher requirements on the environmental protection of the cables used, and it is forbidden to use or import non environmental protection cables. China also attaches great importance to this field. Relevant laws and regulations clearly require that the use of non environmental protection cables is strictly prohibited in major engineering construction. Previously, Beijing and Shanghai have banned the use of non environmentally friendly cables.
Traditional cables not only contain lead, cadmium, mercury and other heavy metals, but also produce a large number of dioxin, lead, cadmium, halide and other hazardous substances in the process of manufacture, use and waste disposal. In case of fire, a large number of smoke will be released, and a large number of corrosive harmful gases will be produced, which not only pollute the environment, but also cause a large number of casualties. Compared with traditional cables, environmental protection cables have high flame retardancy, halogen-free, low mildew, no corrosive gas production, high transmittance and high protection to ultraviolet or water.
1. High flame retardancy: the environmental protection cable can fully ensure the high building requirements for fire protection. In case of fire, the environmental protection cable can not only be difficult to burn, but also prevent the spread of flame and the expansion of disaster after burning.
2. Halogen free: the green environment-friendly insulation layer, sheath and special oxygen barrier material are adopted, which not only makes the environment-friendly cable have good electrical performance, physical and mechanical properties, but also ensures that the product does not contain halogen, solves the "secondary pollution" formed during its combustion, and avoids the carcinogenic "dioxin" substances produced during the combustion of traditional PVC wires.
3. Low toxin: the insulation and sheath of environmental protection cable do not contain lead, cadmium and other heavy metals harmful to human body, and will not pollute the soil and water source during the use and disposal of environmental protection cable. After rigorous toxicity test, the mice were safe under the specified experimental conditions.
4. No corrosive gas: the new type of special coating material without pollution to the environment is adopted, so that the environment-friendly cable will not produce toxic gases such as HCl in the process of production, use and combustion. The acid gas emitted is very small, and the damage to personnel, equipment and instruments is small, showing more environmental protection characteristics.
5. High light transmittance: the smoke generated by the burning of environmental protection cable is very thin, which is conducive to the evacuation and fire fighting work. Generally speaking, the light transmittance of environmental protection cable products is more than 40%, which is far higher than the standard of traditional flame retardant cable with light transmittance less than 20%.
6. High protection of ultraviolet or water: this kind of performance can make environmental protection cable not easy to be weathered in use, slow down the aging speed of environmental protection cable to a certain extent, and extend its service life.
In general, environmental protection cable is the general trend. In recent years, the sales share of environmental protection cable products has expanded rapidly. Due to the characteristics of non-toxic and non polluting to people and the environment, high safety and reliability, and long service life, environmental protection cable will become the mainstream of cable market in the future. Shanghai Qifan Cable Co., Ltd. firmly grasps the industry pioneer trend, increases investment in scientific research and development, and successively develops environmental protection products with outstanding environmental performance, such as low smoke halogen-free flame retardant and fire-resistant cable, mineral insulated cable, etc., which will surely gain a larger market share in the future applications with high environmental requirements.
