In many areas of key projects, such as fire control, surveillance, and alarms, low-smoke halogen-free cables are used in places such as fire control, surveillance, and alarms. People usually call them environmentally friendly cables. In fact, environmental protection cables do not refer to low-smoke halogen-free cables. The detailed analysis of the differences between environmentally friendly cables and low-smoke halogen-free cables:
1, halogen-free:
The use of green insulating layer, jacket and special oxygen barrier material not only has good electrical properties, physical and mechanical properties, but also guarantees that the product does not contain halogen, solves the "secondary pollution" formed during combustion, and avoids When traditional PVC wires burn, they can cause cancer-causing "dioxin" substances.
2, high flame retardant:
The environmental protection cable completely guarantees the construction requirements that require high fire protection. In case of fire, the cable is not easy to burn, and it can prevent the spread of flames and the expansion of disasters after the fire.
3, low toxin:
The insulation and sheathing do not contain lead, cadmium, or other heavy metals that are harmful to the human body and do not pollute the soil or water sources during cable use and disposal. After harsh toxicity experiments, the rats were safe under the specified experimental conditions.
4, no corrosion gas:
The use of new special coating materials that have no pollution to the environment will not produce gases such as HCL during production, use, and combustion, and will emit very little sour gas, which will result in less damage to personnel, equipment, and instruments, and will be more environmentally friendly.
5, waterproof, anti-ultraviolet:
Uses a special molecular structure of green materials to ensure ultra-low water absorption. Special UV absorbers provide good UV protection. Guarantee the safety of this type of product and prolong its service life.
6, high light transmittance:
The smoke generated when the cable is burned is extremely thin, which facilitates the evacuation of personnel and the execution of fire fighting. The light transmission rate of the product is more than 40%, which is far higher than the standard of less than 20% of the transmission rate of the traditional flame-retardant cable.
