According to various sources, Low Smoke Zero Halogen (LSZH) cables present significant advantages in both safety and environmental impact. These cables produce minimal smoke and no halogen gases during combustion, making them a safer option in confined and populated spaces. Their unique thermoplastic jacket offers reliability and flame retardancy, which are essential attributes for many applications.
In densely populated areas and environments like tunnels filled with cabling, fire hazards become a significant concern. Research indicates that the primary threat during the early stages of a fire isn't the flames but rather the smoke generated. When ventilation is limited, smoke can accumulate quickly, posing serious risks. LSZH materials are specifically designed to emit little to no smoke when ignited, consisting of thermoplastic compounds that minimize visibility issues and ensure safe egress paths.
Common cable jackets typically release harmful gases containing halogens when burned. These gases can result in serious health effects, including suffocation and long-term respiratory issues. In contrast, LSZH cables are free from halogen materials, significantly reducing the production of toxic gases during combustion. This makes them a safer alternative, especially in critical environments where personnel safety is paramount.
PVC (polyvinyl chloride) jacketed cables are widely utilized but can emit dangerous smoke and gases if ignited. LSZH cables, however, are thoroughly tested for various safety parameters, ensuring that they meet rigorous standards for fire safety, smoke emission, and halogen content. Additionally, LSZH cables exhibit distinct physical characteristics, being more rigid due to their flame-retardant compositions, whereas PVC cables tend to be softer.
LSZH cables are particularly beneficial in confined spaces that house people or sensitive electronic equipment. Industries such as military, aviation, and public transport systems depend on LSZH cables for their enhanced safety properties. Due to their low emission of toxic gases, these cables ensure better visibility during a fire and protect electrical devices from corrosive harm. Moreover, they are self-extinguishing, reducing the spread of flames in emergencies.
Specifications are rigorously tested in controlled environments, ensuring that LSZH cables satisfy numerous industrial requirements. Furthermore, custom cables can be developed to match specific project needs, addressing various performance criteria.
LSZH cables are increasingly utilized in environments with limited airflow and a high density of people, such as mass transit facilities and underground tunnels. While Europe has widely adopted these cables, the U.S. market is slower to follow suit due to regulatory measures. High-rise buildings, hospitals, data centers, and various aerospace applications are among the settings where LSZH cables provide significant benefits.
LSZH insulation can be applied to a range of cable types, including instrumentation, audio/video, power, and automation cables, among others. In cases where safety and performance standards must be met, LSZH cabling remains the most viable solution.
