What are the characteristics of environmentally friendly wire and cable？

Environmentally friendly wire and cable refers to a new type of wire and cable that is non-toxic and harmless, will not release toxic substances when burned, and will not cause harm to the environment after being discarded. Environmentally friendly cables are wires and cables that do not produce harmful halogen gases, corrosive gases, generate less heat during combustion, and do not pollute the soil. Environmentally friendly wires and cables are different from ordinary wires and cables, not only in materials and processes, but also in performance and quality standards.

Performance of environmentally friendly wire and cable:

1.Flame retardant and fire resistance, the flame retardant and fire resistance of environmentally friendly wires and cables fully meet the national fire protection standards. In the event of an electrical fire, the wires and cables are not easy to burn. Flame spread after burning cables

2.The insulation materials and sheath materials used in environmentally friendly wires and cables are environmentally friendly materials. While ensuring stable electrical performance and physical and mechanical functions, the performance of wires and cables is guaranteed, and the “secondary pollution” formed after waste wires and cables are incinerated “.

3.Low toxicity and environmental protection According to the particularity of the materials used, the insulation and sheath do not contain heavy metals such as lead and cadmium that are harmful to the human body, which can ensure our own health during daily use.

4.No corrosive gas will be decomposed. Environmentally friendly wires and cables are made of new special materials, which will not produce a variety of toxic gases due to high temperature and other reasons during use. The harm to equipment and instruments is small, and the environmental protection features are more prominent.

5.Has high flame retardancy. It is reported that flame retardancy is very important, which can completely ensure safe and fireproof cables. Wires and cables are not easy to burn and catch fire, and prevent flames from expanding.

6.No peculiar smell, corrosive smell, no hydrochloric acid and other toxic gases. It is a new type of environmentally friendly coated cable produced in an environmentally friendly way. It does not produce acid gas or discharge very little during use or combustion, ensuring the safety of personnel and reducing damage to equipment and machines.

7.High light transmittance, the smoke produced by combustion is very thin, which is conducive to evacuation and fire fighting. The light transmittance exceeds 40%, which is much higher than the standard of less than 20% for traditional flame-retardant cables.

8.Halogen-free, green insulation, special oxygen barrier material, not only has excellent electrical and mechanical properties, but also does not contain halogen in the product, which prevents carcinogenic substances from burning traditional PVC wires during combustion and avoids secondary pollution.

9.Waterproof and anti-ultraviolet performance, its special molecular structure ensures the manufacture of environmentally friendly materials with ultra-low water absorption. The special UV absorber makes the product have excellent UV protection performance.

Production requirements for environmentally friendly wire and cable:

1.First of all, it does not contain heavy metals. Ordinary PVC cables are often mixed with lead, cadmium, barium and other heavy metals that are harmful to the human body. Later, some countries stipulated that the content of eight types of heavy metals should not exceed the specified value, and the environmental protection cable A major advantage is that it does not contain heavy metals, which is also a popular selling point in the market.

2.The second requirement of environmentally friendly cables is low-smoke and halogen-free. Ordinary cables will release a lot of smoke and toxic gases when they burn, which will seriously pollute the air environment and cause harm to the human body. The low-smoke and halogen-free characteristics of environmentally friendly cables can not only protect the environment It can also help people evacuate and carry out fire rescue work when a fire breaks out.

3.Also non-toxic, all ingredient materials used in PVC formulations should be non-toxic. Cable materials contain a large amount of plasticizers, but non-toxic plasticizers must be selected for the manufacture of non-toxic materials. Therefore, the requirements of this PVC material are higher than those of lead-free and heavy metal-free materials, and the price is naturally more expensive.
