Low-smoke, halogen-free (LSZH) cables are used in many areas of critical projects, such as fire protection, surveillance, and alarm systems. They are often referred to as environmentally friendly cables. However, environmentally friendly cables do not necessarily refer to LSZH cables. The following is a detailed analysis of the differences between environmentally friendly cables and LSZH cables.
1. Halogen-free:
Using green, environmentally friendly insulation, sheathing, and specialized oxygen barrier materials, LSZH cables not only offer excellent electrical and mechanical properties but also guarantee halogen-free performance, eliminating the "secondary pollution" caused by combustion and avoiding the carcinogenic dioxins produced by traditional PVC cables. Shenzhen Jinhuanyu Wire and Cable Co., Ltd. produces LSZH cables.
2. High Flame Retardancy:
Environmentally friendly cables fully meet the requirements of buildings with strict fire protection requirements. They are resistant to combustion during fires and can prevent the spread of flames and the expansion of damage.
3. Low Toxins:
The insulation and sheathing do not contain harmful heavy metals such as lead and cadmium, ensuring that the cables will not pollute soil or water during use or disposal. After rigorous toxicity testing, the mice remained unharmed under the prescribed experimental conditions.
4. No Corrosive Gases:
Using a new, environmentally friendly special coating material, the cable does not produce gases such as HCl during production, use, or combustion. The acid gas emissions are minimal, minimizing damage to personnel, equipment, and instruments, further enhancing its environmental protection.
The above is an introduction to the difference between environmentally friendly cables and low-smoke halogen-free cables, which I believe you are familiar with. Low-smoke halogen-free cables are just one type of wire and cable. Broadly speaking, low-smoke halogen-free cables are not necessarily environmentally friendly, but environmentally friendly cables must be low-smoke halogen-free cables.
