Ordinary wires and cables will release hydrogen halide or other acidic gases when heated and burned, which is polluting to a certain extent, and the smoke produced will hinder the visibility of fire fighting and rescue. Low-smoke halogen-free cables perfectly solve this problem and can protect personnel and equipment from toxic and corrosive gases. What is the difference between low-smoke halogen-free cables and ordinary wires? Let's take a closer look.

What is LSZH Cable?

(1) Definition.

LSZH, LSOH, LS0H, LSFH and OHLS are referred to as LSZH, LSOH, LS0H, LSFH and OHLS, which are material classifications for wire sheaths in the wire and cable industry. LSZH wire sheaths are composed of thermoplastic or thermoset and contain no halogens to reduce the generation of toxic and corrosive gases during combustion.

(2) Performance characteristics.

1. Halogen-free.

Adopt green environmental protection insulation layer. The sheath and the special oxygen barrier material not only have good electrical properties. physical and mechanical properties, and to ensure that the product is halogen-free. It solves the secondary pollution formed in the burning process and avoids the toxic substances produced in the burning process of traditional PVC wires.

2. Low smoke and low toxicity.

It is produced with a new type of special coating material that is non-polluting to the environment. No toxic gas will be generated during use and combustion, and the emission of acid gas is very small, reducing damage to personnel and equipment. In the case of concentrated personnel, it is very necessary to use low-smoke halogen-free cables.

3. Environmental protection.

The insulation and sheath do not contain lead, cadmium and other heavy metals that are harmful to the human body. When the cable is used and discarded, it will not pollute the soil and water sources, and it is more environmentally friendly than traditional cables. Low-smoke halogen-free cables, also known as environmentally friendly cables, are very friendly to the environment.

4. High flame retardancy.

The environmentally friendly cable guarantees its building requirements for high fire protection requirements. The cable is not easy to burn in a fire, which can prevent the spread of the flame and the expansion of the disaster after burning. Especially in modern buildings, the emergence of super high-rise buildings and modern material products has increased the difficulty of rescue in the event of a fire. The use of low-smoke, halogen-free cables can increase the rescue time and reduce the harm of harmful gases to the human body.
