Low-smoke and halogen-free cables are used in many places of key cable projects, such as fire fighting, monitoring and alarm. Usually, people call them environmental protection cables, but in fact, environmental protection cables do not refer to wdz.
1.Halogen-free: The use of green insulation layer, sheath and special oxygen barrier material not only has good electrical performance and physical and mechanical properties, but also ensures that the product is halogen-free, solves the "secondary pollution" caused by its combustion, and avoids the generation of carcinogenic "dioxin" substances when traditional PVC wires are burned.
2.High flame retardancy: the environmental protection cable fully meets the building requirements with high fire protection requirements, and the cable is not easy to burn in case of fire, and can prevent the spread of flame and the expansion of disasters after burning.
3.Low toxicity: the insulation and sheath do not contain heavy metals harmful to human body, such as lead and cadmium, and will not pollute soil and water sources when cables are used and discarded. And after harsh toxicity experiments, the white rats are safe and sound under the specified experimental conditions.
4.No corrosive gas: A new type of special coating material that is pollution-free to the environment is adopted, which will not produce HCL and other gases during production, use and combustion, and will emit little acid gas, which will cause little damage to personnel, equipment and instruments, and is more environmentally friendly.
5.Waterproof and UV-proof: adopt green materials with special molecular structure to ensure ultra-low water absorption. Special ultraviolet absorber makes the product have good anti-ultraviolet function. It ensures the safety of this kind of products and prolongs the service life. The name of "environmental protection cable" was first initiated by a Japanese company, and its product standard was FN(Ecomaterial) ecological cable standard. In western countries, Britain also formulated advanced environmental protection cable standard requirements.
6.High light transmittance: the smoke generated when the cable burns is extremely thin, which is beneficial to the evacuation of personnel and the fire fighting work. The light transmittance of the product is more than 40%, which is far higher than the standard that the light transmittance of traditional flame retardant cables is less than 20%.
