In key projects, low smoke halogen-free wires and cables are used in many places, such as fire control, monitoring and alarm, which are usually called environmental protection cables.

 

In fact, the environmental protection cable does not refer to the low smoke halogen-free wire and cable, but the cable produced according to the cable manufacturing standard of FN in Japan!!!

 

With the global promotion and spread of the concept of green environmental protection, 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 R & D and promotion of environmental protection cables.

 

China also attaches great importance to this field. Relevant laws and regulations explicitly require that non environmental protection cables are strictly prohibited in major project construction.

 

So what is environmental protection cable and what are its characteristics?

 

1. High flame retardancy

 

The environmental protection cable can fully ensure the building requirements with high fire protection requirements. 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 combustion.

 

2. Halogen free

 

The use of green environmental protection insulation layer, sheath and special oxygen isolation layer materials not only makes the environmental protection cable have good electrical and physical and mechanical properties, but also ensures that the product does not contain halogen, solves the "secondary pollution" formed during 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 cables do not contain heavy metals harmful to human body such as lead and cadmium, which will not pollute soil and water sources during the use and waste treatment of environmental protection cables. After rigorous toxicity experiments, the white mice were safe under the specified experimental conditions.

 

4. No corrosive gas is produced

 

The new special coating material without pollution to the environment is adopted, so that the environmental protection cable will not produce HCl and other toxic gases during production, use and combustion, with very little acid gas emission, less damage to personnel, equipment and instruments, and more environmental protection characteristics.

 

5. High transmittance

 

The smoke generated by the burning of environmental protection cables is very thin, which is conducive to personnel evacuation and fire fighting. Generally speaking, the light transmittance of environmental protection cable products is greater than 40%, which is much higher than the standard that the light transmittance of traditional flame retardant cables is less than 20%.

 

6. High UV or water protection

 

This performance can make the environmental protection cable less easily weathered in use, slow down the aging speed of the environmental protection cable to a certain extent and prolong its service life.

 

Generally speaking, environmental protection cable is the general trend. In recent years, the sales share of environmental protection cable products has expanded sharply. Because environmental protection cable has the characteristics of non-toxic and pollution-free to people and the environment, high safety and reliability, long service life and so on, it is expected to become the mainstream of the cable market in the future.
