Unlike PVC cables and those made of other compounds which produce vast amounts of dense black smoke, toxic fumes and acid gas when exposed to fire, LSZH cables produce very low levels of smoke and toxic fume and no acid gases.
Secondly, is EPR halogen free?
Halogen-free materials for cables
There are several halogen-free materials that can be used for cables. These include EVA, Polyamides, EPR, EPDM, PE, PP, SHF1 and SHF2.
Then, is PVC cable halogen free?
The halogen-free material is a material that does not contain a group of halogen elements (fluorine, chlorine, bromine, iodine, and astat). … PVC or polyvinyl chloride is not a halogen-free material because it contains chlorine.
Is rigid conduit 2 hour fire rated?
It is listed as a 2-hour fire-rated electrical circuit protective system when installed in ½-in. minimum electrical metallic tubing (EMT) or rigid metal conduit (RMC) and is ideal for retrofit applications in existing conduit.
Should I use low smoke 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 cable uses a halogen free jacket material?
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).
What is halogen-free conduit?
Electri-Flex Company manufactures many types of low-smoke, halogen-free (LSZH) flexible electrical conduits that virtually eliminate the release of the toxic gases found in PVC products. … LSZH reduces the amount of smoke and flame spread, which can allow people more time to easily escape areas of fire.
What is Lsoh conduit?
Conduit is LSZH (Low Smoke Zero Halogen) more commonly referred to as HFT and is largely used in tunnels, theatres, shopping centre and anywhere that there is a large public presence. Product gives off no toxic fumes or gases and releases no toxic halogens.
What is the purpose of halogen free cable?
Halogen free or zero halogen cabling is used in many areas of the cable and wiring industry, including aircraft, rail and construction. Used to protect wiring, it is proven to limit the amount of toxic gas emitted when it comes into contact with heat.
Where can I use halogen-free cables?
Where are halogen-free cables used? Great attention should be paid to the use of halogen-free cables, especially in applications with increased fire hazard. So if a cable is used where there is an increased risk of fire, the absence of halogen excludes a risky source of hazard.
