The manufacturing process for wires and cables differs significantly from that of most electromechanical products. It begins with the processing of the conductor, and then gradually adds layers of insulation, shielding, cabling, and sheathing to create the finished wire and cable product. The more complex the product structure, the more overlapping layers are required. How do environmentally friendly wires and cables differ from traditional cables? What are their advantages?
What is the difference between environmentally friendly cables and ordinary cables?
Environmentally friendly wires and cables differ not only in material and craftsmanship, but also in performance and quality standards. This is primarily reflected in the following aspects:
1. Flame retardancy and fire resistance: Environmentally friendly wires and cables have flame retardancy and fire resistance that fully meet national fire protection standards. In the event of an electrical fire, they are less likely to burn. They can also maintain normal operation of the circuit system for a certain period of time even if the fire continues, and they minimize the spread of flames after the fire.
2. Low toxicity of wires and cables: Due to the special raw materials used, environmentally friendly wires and cables do not contain harmful heavy metals such as lead and cadmium in their insulation and outer sheathing, ensuring maximum health and safety during daily use.
3. No corrosive gases released by wires and cables: Environmentally friendly wires and cables are made of new, non-polluting specialty materials. During use, they do not produce toxic gases due to high temperatures, minimizing the risk to equipment and instruments, further highlighting their environmentally friendly nature.
4. No pollution: The insulation and sheathing materials used in environmentally friendly wires and cables are all green and environmentally friendly. While ensuring high-quality and stable electrical performance and physical and mechanical functions, they also guarantee safety and avoid the "secondary pollution" caused by the incineration of waste wires and cables.
What are the advantages of environmentally friendly cables over conventional cables?
1. High flame retardancy. As we all know, flame retardancy is crucial for wires and cables. Cables that fully meet fire safety requirements are less likely to ignite and can prevent flames from spreading.
2. New, environmentally friendly coated wire and cable materials are odorless and corrosive, and contain no hydrochloric acid or other toxic gases, resulting in no pollution to the environment. During use and combustion, no or very little acidic gas is emitted, ensuring personnel safety and minimizing damage to equipment and instruments.
3. High light transmittance. The smoke produced by burning environmentally friendly wire and cable is very thin, facilitating evacuation and firefighting. The product's light transmittance exceeds 40%, significantly exceeding the standard of less than 20% for traditional flame-retardant cables, and even surpasses this.
4. It is halogen-free, green insulation, and uses a special oxygen barrier material. This material not only offers excellent electrical and mechanical properties, but also contains no halogens, preventing the formation of carcinogenic dioxins during combustion, as is the case with traditional PVC cables, thus preventing secondary pollution.
5. The environmentally friendly wire and cable is waterproof and UV-resistant. The unique molecular structure of the environmentally friendly wire and cable ensures the production of green, environmentally friendly materials with ultra-low water absorption. Special UV absorbers provide excellent UV protection.
These are the differences and characteristics between environmentally friendly cables and conventional cables. In recent years, with the increasing emphasis on environmental protection, the requirements for wires and cables—the "blood vessels" and "nerves" of industry and the national economy—are also becoming increasingly stringent. Environmentally friendly cables are increasingly being used in important applications such as locomotives, ships, subways, and large entertainment venues. In addition, everyday items such as electric toys and household appliances should also utilize environmentally friendly wire and cables. Therefore, it is clear that environmentally friendly cables and wires will be widely used in the near future.
