Galaxy is a leading low smoke zero halogen (LSZH) cable supplier offering custom and stock LSZH cable and LSZH wire. LSZH cables are often used where safety, along with performance and reliability, are critical. They are typically specified for use in highly populated, enclosed public spaces where flame resistance, low smoke production and reduced toxic/corrosive gas emissions during combustion are critical.
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.
Low smoke zero halogen cables are used when fire safety is critical, especially in enclosed spaces. A number of fires in transportation facilities and other locations led to the development of LSZH cables. In these emergency fire situations, the low smoke factor helps maintain visibility and can reduce respiratory damage, while zero halogen material cuts the production of toxic, halogenated gases.
Halogen free cable/wire, also called zero halogen cable, refers to cables where the cable jacketing and insulation is made with materials that produce no toxic halogens when exposed to fire or high temperatures. These halogen free cables are used when smoke considerations are minimal. Halogen-free cables also do not use materials that may have an environmental impact.
Low smoke cable/wire, also called limited smoke cable, refers to cables where the cable jacketing and insulation is made with materials that produce no or only small amounts of smoke when exposed to fire or high temperatures. These low smoke cables are used when halogen considerations are minimal.
Because of their low smoke and toxicity benefits, LSZH cables are often chosen for a multitude of applications. These include:
LSZH insulation and jacketing can be used to manufacture nearly any type of cable, including but not limited to:
SUNUA contains other products and information you need, so please check it out.
In some locations, there are regulations that require the use of low smoke zero halogen wire/cable. Local codes should be checked to see if LSZH wires are required.
Galaxy has successfully transitioned a large number of cable projects from unapproved cable specifications to cables that now meet stringent low smoke zero halogen requirements. This expertise and experience is a strong reason to choose Galaxy for LSZH cable.
Also, there are various combinations of cable compounds with different characteristics. There are some low-smoke compounds that are not halogen free, and some halogen free compounds that are not considered low smoke. Galaxy&#;s Sales Engineers can provide guidance in selecting a cable solution that is well suited for specific applications and understand the challenges that come along with the cable selection process. No matter the environment or desired functionality of the cable, a LSZH cable can be manufactured that allows equipment to function as intended when fire and smoke safety is critical.
