Low smoke zero halogen or low smoke free of halogen (LSZH or LSOH or LS0H or LSFH or OHLS or ZHFR) is a material classification typically used for cable jacketing in the wire and cable industry. LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat.

Prysmian’s LSX cable has been specifically designed for use in buildings and can easily replace many standard PVC cables. It is described as a low smoke zero halogen (LSOH) screened wiring cable. But what do these terms actually mean?

Jan 3, 2017 · LSHF Cables when burnt give off very little smoke, grey in colour and little or no hydrogen chloride. There is a complete lack of PVC in these cables, hence no harmful fumes are given off in case of fire. They are manufactured from thermoplastic compounds meaning no halogen is emitted.

Jul 18, 2018 · IEC 62821 covers requirements for halogen-free, low-smoke thermoplastic insulated and sheathed cables with voltage ratings up to 750 volts. UL’s HF and LZSH markings can be used on many types of wire and cable, from appliance wiring to communications cable (including fiber optic), flexible cord, and power and control tray cable.

We supply a comprehensive range of Low Smoke Zero Halogen (LSZH) cables for use in applications where smoke emission and toxic fumes could pose a risk to human health and essential equipment in the event of a fire. The cables are also commonly referred to as ZHLS cables or halogen free cables.

Whilst we generally refer to this cable insulation and sheathing compound as LSZH, other references include LSHF (Low Smoke Halogen Free), 0HLS / ZHLS (Zero Halogen Low Smoke), and HFFR (Halogen Free Flame Retardant). cables which often have flame

When burned, a low-smoke cable (also known as limited-smoke cable) emits a less optically dense smoke that releases at a lower rate. During a fire, a low-smoke cable is desirable because it reduces the amount and density of the smoke, which makes exiting a space easier for occupants as well as increases the safety of firefighting operations.

Feb 7, 2023 · Low smoke zero halogen (but also called LSZH, LSOH, LS0H, LSFH or OHLS) is a material classification that is common to cable and wire casings. When exposed to flames and high levels of heat, LSZH materials produce very little visible smoke (compared to PVC and other similar materials) and no halogens, which can be harmful to humans.

Low smoke zero halogen (hereafter referred to as LSZH but also called LSOH, LS0H, LSFH or OHLS) is a material classification that is common to cable and wire casings.
