What is halogen cable?
Halogen-free cables are cables whose materials are not processed with the elements of the halogen group. As non-conductors, halogens such as chlorine are excellent insulators and are therefore often used as jacket material for cables. The most common example of this is polyvinyl chloride (PVC).
What is LSF cable used for?
LSF/LSZH cables are popular in places where people live close to cable assemblies and cannot get sufficient ventilation during the fire. These cables find vast application in skyscraper, malls, large commercial spaces, military, railroad, maritime and aerospace.
What is the difference between PVC and LSZH cable?
A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns.
Where should LSZH cable be used?
They are therefore often specified indoors, especially in public areas, and in other hazardous environments and poorly ventilated areas. This includes cars, aircraft, railway carriages and ships. LSZH sheathed cables are commonly used across tunnels and underground rail networks.
What does low halogen mean?
Within Intel, the term “low-halogen” is defined in Clause 4 of JEDEC JEP 709 and is used to identify solid state devices that contain low concentrations of bromine and chlorine from brominated and chlorinated flame retardants (BFRs, CFRs).
Is halogen free cable low smoke?
HF = Halogen free. LS = low, limited smoke. FRLS = fire resistant, low smoke.
Is LSF a PVC cable?
LSF (Low Smoke & Fume) Cables LSF cables are usually made up of a modified PVC compound which produces somewhat less HCL gas and smoke on burning than PVC. However, it still produces 15% to 22 % (depending on quality) of HCL gas and due to the presence of PVC can still emit dense black smoke.
Do you have to use LSF cable?
The use of LSOH cables is not a requirement of BS 7671 in domestic or Non-domestic buildings at present. The use of these cables is often subject to specification requirements rather than regulation. Regulations, however, may soon require such cables when installed in escape routes in certain buildings.
What is LSZH wire?
LSZH cable/wire refers to cables where the cable jacketing and insulation is made with materials that produce low/limited smoke and non-toxic halogens when exposed to fire or high temperatures. There is also low smoke cable and zero halogen cable / halogen free cable.
Do I have to use LSF cable?
Is XLPE cable LSF?
Application: The power and control cables with insulation of cross-linked polyethylene (XLPE) type LSOH are flame retardant, with low halogen free smoke emission and corrosion at fire conditions and are suitable for use in electrical installations for nominal voltage Uo/U 0.6/1 kV.
