Understanding Low Smoke Zero Halogen (LSZH) Cables
Low Smoke Zero Halogen (LSZH) refers to cable jacketing materials that emit minimal smoke and no toxic halogen gases (like chlorine or fluorine) when exposed to high heat. This makes them a critically important component for safety in many installations.
Key Safety Features
- Low Smoke Emission: LSZH cables produce significantly less smoke than standard PVC, improving visibility for safe evacuation during a fire.
- Zero Halogen Toxicity: They do not release harmful halogen gases, reducing the risk of injury from inhaling toxic fumes.
- Non-Corrosive: The lack of acidic gases during combustion protects sensitive electronic equipment from damage.
Common Applications
- Poorly Ventilated Areas: Ideal for confined spaces such as aircraft, rail carriages, ships, and submarines.
- Public Infrastructure: Widely used in tunnels and other public transport systems where ventilation is limited.
- High-Risk Facilities: Essential in data centres and nuclear facilities to protect both people and expensive equipment.
LSZH vs. PVC Cables
Compared to standard PVC cables, LSZH provides superior fire safety and is more environmentally sustainable, though it is generally more expensive and slightly less flexible. The choice depends on balancing budget with the specific safety requirements of the installation environment.
