In many areas of key projects, such as fire protection, monitoring, alarm, places will be used LSZH cable, people usually call it environmental protection cable, in fact does not refer to the environmental protection cable low smoke halogen-free cable, the following is a detailed analysis of the difference between non halogen low smoke cables and cable protection:
1. Halogen free:
The green jacket insulation layer, and a special oxygen barrier layer material, not only has good electrical properties, mechanical properties, and ensure that the product does not contain halogen, solves its combustion to form a "two pollution", to avoid the traditional PVC wires produced during the combustion of carcinogenic substances "dioxin".
2. High flame retardancy:
The environmental protection cable guarantees its high requirements for fire protection. The cable is not easy to burn in fire, and it can prevent the spread of fire and the expansion of disaster.
3, low toxin:
The heavy metals, which do not contain lead and cadmium in the insulation and sheath, will not pollute the soil and water when the cable is used and discarded. And after a severe toxicity test, the mice were safe and sound under the prescribed experimental conditions.
