1000V Low Smoke Zero Halogen Wire

1000V Low Smoke Zero Halogen Wire

What is LSZH Cable?

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.

Benefits of LSZH 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.
