How much do you know about the trend of environment-friendly cables and six features?In many key projects, such as fire protection, monitoring, alarm and other places will use low-smoke halogen free wire and cable, usually people will call it environmental protection cable.

With the promotion and spread of green environmental protection concept in the world, the concept of environmental protection is gradually permeating into all walks of life, and with the gradual use of environmental protection products and deeply rooted in the hearts of people, the wire and cable industry also began to pay attention to the research and development and promotion of environmental protection cable.

China also attaches great importance to this field. Relevant laws and regulations require that non-environmental protection cables should be strictly prohibited in major engineering construction.

So what is environmental protection cable, it has what characteristic again?

Environmental protection cable refers to the cable does not contain lead, cadmium, hexavalent chromium, mercury and other heavy metals, does not contain bromine flame retardant, by the SGS recognized testing institutions of environmental protection performance test, in line with the eu environmental protection directive (RoSH) and higher than its index requirements.Do not produce harmful halogen gas, do not produce corrosive gas, have a low fever when burning, do not pollute the soil wire and cable.

1. High flame resistance

Environment-friendly cable can completely guarantee its high requirements for fire protection. In case of fire, environment-friendly cable can not only not be easy to burn, but also prevent the spread of flame and the expansion of disaster after burning.

2. Halogen free

The use of green environmental protection insulation layer, sheath and special oxygen layer material, not only makes the environmental protection cable has good electrical properties, physical and mechanical properties, and ensure that the product does not contain halogen, solve the formation of its combustion of the "secondary pollution", to avoid the traditional PVC wire combustion can produce carcinogenic "dioxin" material.

3. Low toxin

The insulation and sheath of environment-friendly cables do not contain heavy metals harmful to human health, such as lead and cadmium, which will not cause soil and water pollution when the cables are used and discarded.And after rigorous toxicity tests, the mice were safe and sound under the prescribed experimental conditions.

4. No corrosive gas is generated

The new type of special coating material with no pollution to the environment is adopted, so that the environment-friendly cable will not produce HCL and other toxic gases in the production, use and combustion process, and the emission of acid gas is very small, which will cause little damage to personnel, equipment and instruments, and show more environment-friendly features.

5. High light transmittance

The smoke generated by the burning of environment-friendly cables is extremely thin, which is conducive to the evacuation and fire fighting of personnel.Generally speaking, the light transmittance of environment-friendly cable products is more than 40%, far higher than the standard of less than 20% of the light transmittance of traditional flame retardant cables.

6. High protection against ultraviolet rays or water

This kind of performance can make the environmental protection cable is not easy to be weathered in use, to a certain extent, slow down the environmental protection cable aging speed, extend its service life.

In general, environmentally friendly cable is the trend.In recent years, the sales share of environment-friendly cable products has increased sharply. Due to the non-toxic and pollution-free characteristics of environment-friendly cables, such as high safety and reliability, long service life, etc., environment-friendly cables are expected to become the mainstream of the cable market in the future.
