What cable uses a halogen free jacket material?
What does LSZH mean.
LSZH stands for low smoke zero halogen.
The compounds in the cable insulation and jacket have no fluorine, chlorine, bromine, iodine, or astatine.
This means that the cable emits little to no toxic halogens and minimal smoke when in contact with fire..
Is XLPE low smoke?
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. … There are several similar classifications such as low smoke and fume (LSF) and low smoke varieties of PVC and cross-linked polyethylene (XLPE).
Is PTFE halogen free?
By comparison PTFE base materials do not contain bromine and should not be included in the “halogen-free” debate. Fluorine is the most electronegative of elements and forms an extremely strong bond with carbon.
Is XLPE a Lszh?

Is PVC cable fire resistant?
LSOH and PVC cables are for non-essential services that do not need to operate in a fire. … These circuits are not essential for the safety of the public; they can fail in a fire with no increase in danger so they do not need to be fire resistant.
What is the difference between LSF and LSZH cable?
LSF cable will emit toxic gases while LSZH will limit the emission of these (typically under 0.5% hydrogen chloride emission). In addition to being toxic, hydrogen chloride is corrosive to equipment. The use of LSZH cables protects both people and limits the amount of equipment damage during a fire situation.
What does LSF cable mean?
Low Smoke & FumeLow Smoke & Fume (LSF)
What is halogen free cable?
Halogen-free cables are free of elements such as bromine, fluorine, iodine or chlorine, which are all very reactive. … In the case of halogen-free cables no toxic or corrosive gases are released in a fire, which could be a threat to humans or buildings.
Is PVC a Lszh?
What’s the difference between PVC and LSZH cables 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.
Why is halogen free important?
Low smoke and halogen free products are used to protect wiring, as they are proven to limit the amount of toxic gas emitted when it comes into contact with heat.
What is the difference between PVC and XLPE?
XLPE Cables have higher current rating and longer service life compared to PVC Cables. Under short circuit condition,this cable can withstand up to 250ºC temperature compared to 160ºC for PVC cables. … It also has 100 times more moisture resistance capacity compared to PVC.
What is a low smoke cable?
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.
