In a sense, the wire and cable manufacturing industry is a material sorting and assembly industry. First of all, the amount of materials is large, and the material cost of cable products accounts for 80%-90% of the total manufacturing cost. Secondly, there are many types and varieties of materials used, and the performance requirements are particularly high. Third, the choice of materials can have a decisive impact on the manufacturing process, product performance and service life.

Environmentally friendly wires and cables are different from ordinary wires and cables, not only due to different materials and processes, but also greatly different performance and quality standards.

1. Flame retardant and fire resistance: The flame retardant and fire resistance fully complies with the national fire protection standards. When an electrical fire occurs, wires and cables are not easy to burn. Continuous burning can ensure the normal operation of the circuit system for a period of time and reduce the spread of flames after the wires and cables are burned.

2. The insulation materials and sheath materials used for environmentally friendly wires and cables are all environmentally friendly materials. While ensuring stable and reliable electrical performance and physical and mechanical functions, they also ensure the performance of wires and cables and avoid "secondary damage" caused by scrapping wires and cables. pollute".

3. Low toxicity: Due to the particularity of the raw materials used, the insulation and sheathing of green wires and cables do not contain heavy metals such as lead or cadmium that are harmful to the human body, so they can protect our own health during daily use.

4. Does not decompose corrosive gases. Environmentally friendly wires and cables are made of new special materials that do not produce a variety of toxic gases due to high temperatures and other reasons during use. They cause less harm to equipment and instruments and highlight the environmental characteristics of environmentally friendly wires and cables.

The insulation of ordinary decoration wires is basically made of polyvinyl chloride (PVC) material. Green wires use cross-linked polyethylene as the insulating material, which has high heat resistance, safety and stability. In summary, the main points are as follows:

1. Cables, wires and cables that have high flame retardancy and fully meet safety and fire protection requirements are not easy to catch fire and can prevent the flame from expanding.

2. Due to the odorless and corrosive odor, new environmentally friendly coatings that do not contain hydrochloric acid and other toxic gases and have no environmental pollution, wire and cable materials, do not produce or emit almost no acidic gases during use and combustion, and have the ability to ensure personnel safety. , reduce equipment damage and other environmentally friendly features.

3. High light transmittance, the smoke produced by the burning of environmentally friendly wires and cables is very thin. Helps with evacuation and digestion. The light transmittance of the product is greater than 40%, which is much higher than the light transmittance of traditional flame-retardant cables, which is much higher than the standard of less than 20%.

4. Halogen-free, green insulation, and special oxygen barrier substances can ensure electrical and mechanical properties and that the product does not contain halogen. During the combustion process, it prevents traditional PVC wires from burning, producing carcinogens, and preventing secondary pollution.

5. Waterproof and anti-ultraviolet performance, special molecular structure, ensuring the production of environmentally friendly materials with ultra-low absorption rate. Special UV absorbers provide the product with good sun protection properties.
