LSZHpäällysteitä

LSZHpäällysteitä is a Finnish term referring to low smoke zero halogen sheathing. This type of sheathing is a material used for the outer protective layer of cables. Unlike traditional PVC sheathing, LSZH materials are designed to emit very little smoke and no toxic halogenated gases when exposed to fire. This characteristic is crucial for safety in enclosed spaces where smoke inhalation can be a significant hazard.

The "low smoke" property means that the amount of smoke produced during a fire is significantly reduced, improving visibility for escape and rescue operations. The "zero halogen" aspect indicates that the material does not release corrosive or toxic halogenated compounds, such as chlorine or bromine, when burned. These compounds can damage electronic equipment and pose serious health risks.

LSZH sheathing is commonly used in public buildings like hospitals, schools, airports, and underground transit systems, as well as in data centers and telecommunication facilities where the protection of equipment and human life is paramount. The adoption of LSZH cables contributes to enhanced fire safety and reduces the potential for secondary damage caused by corrosive smoke. While LSZH cables may have a slightly higher initial cost compared to standard PVC cables, the safety benefits and reduced long-term damage potential often justify the investment.
