Low smoke zero halogen cable, referred to as LSZH, LSOH, LS0H, LSFH and OHLS, is a material classification of wire sheaths in the wire and cable industry.Low smoke zero halogen wire sheaths are composed of thermoplastic or thermosetting materials that emit low levels of smoke when heated and do not contain halogens.
Low-smoke and halogen-free wire does not contain halogens and does not produce dense smoke when burning. It is non-toxic and environmentally friendly.Compared to ordinary PVC wire, halogen-free low-smoke wire is suitable for home decoration.
Low-smoke and halogen-free cables, also known as green cables, non-polluting cables, clean cables, etc., refer to environmentally friendly cables that do not produce toxic smoke (such as hydrogen halides, carbon monoxide, carbon dioxide, etc.) during combustion. They are made of rubber materials and contain no halogens (F, Cl, Br, I, at), lead, cadmium, chromium, mercury, and other environmental substances.
The so-called low smoke emphasizes that there will not be a large amount of thick smoke after combustion.Halogen-free refers to the fact that during the production of cables, some chemicals such as chlorine and fluorine are not added, as these chemicals emit toxic gases when burned, causing toxicity to the human body.Therefore, low smoke and halogen-free cables are a more environmentally friendly type of cable.
