What is a Low Smoke Zero Halogen (LSZH) Cable?

If you’re looking for a secure and environmentally friendly cable, you may want to consider a low smoke zero halogen cable. This type of cable produces very little smoke and no harmful halogen gasses in the event of a fire.

These cables are often used in public buildings, such as hospitals and schools, as they offer a safer alternative to traditional PVC cables.

What Is Low Smoke Zero Halogen Cable?

What is the meaning of zero halogen? Low Smoke Zero Halogen (LSZH) is an indoor broadband cabling system that, when used in conjunction with non-combustible cables, can significantly reduce the number of toxic elements emitted by the cable and adjacent wiring.

This is a more secure option in areas where smoke and fumes can be hazardous, such as: hospitals, schools, and other public places. LSZH cable is made from materials that do not release halogens or corrosive gasses when burned, making it an option that is less harmful for the environment.
