What is LSZH/LS0H Cable?


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.

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.

There are several similar classifications such as low smoke and fume (LSF) and low smoke varieties of PVC and cross-linked polyethylene (XLPE). Materials with these classifications have similar properties, but often fail to meet prescribed specifications.
