Low-smoke, halogen-free, flame-retardant cable
Low Smoke Zero Halogen (LSZH) Flame Retardant Cable – Product Introduction
The Low Smoke Zero Halogen (LSZH) Flame Retardant Cable is designed to meet the highest requirements for fire safety, environmental protection, and reliable electrical performance in modern power and control installations. Unlike conventional PVC cables, LSZH cables are manufactured using advanced halogen-free flame-retardant compounds that significantly reduce smoke generation and completely eliminate the release of toxic and corrosive gases when exposed to fire.
In the event of a fire, LSZH cables help maintain clearer visibility, reduce the risk of toxic gas inhalation, and minimize secondary damage to equipment and building structures. At the same time, their flame-retardant construction effectively limits flame spread along cable routes, helping to control fire development and reduce overall losses. LSZH flame retardant cables are widely used in public buildings, high-rise projects, subways, tunnels, airports, hospitals, data centers, rail transit systems, marine applications, and industrial facilities, where strict fire safety and environmental standards are required. The cables comply with major international standards such as IEC, EN, and GB, ensuring stable quality and global market acceptance.
Key Selling Points
1. Superior Fire Safety with Low Smoke Density and Zero Halogen Emission
LSZH flame retardant cables are specifically engineered to perform safely in fire emergencies. When burning, they produce very low smoke density, which significantly improves visibility in enclosed and crowded environments such as corridors, underground facilities, and transportation systems. This allows people to evacuate more quickly and safely, reducing panic and potential injuries. More importantly, because LSZH materials contain no halogen elements, the cables do not release toxic or corrosive halogen gases during combustion. This greatly reduces the risk of suffocation and prevents severe corrosion to metal structures, electrical cabinets, and sensitive electronic equipment. As a result, LSZH cables are the preferred solution for life-safety-critical and high-occupancy applications.
2. Excellent Flame Retardant Performance and Enhanced System Reliability
Manufactured with high-quality flame-retardant LSZH compounds, the cable effectively inhibits flame propagation along its length. This helps prevent fire from spreading rapidly through cable trays, ducts, and vertical shafts, limiting fire damage and protecting adjacent systems. In addition, LSZH materials maintain better insulation stability under elevated temperatures, enabling critical circuits such as emergency power supplies, fire alarm systems, emergency lighting, and communication networks to remain operational for a longer time during fire incidents. Compliance with international flame retardancy standards, including IEC 60332, ensures consistent and dependable performance in demanding and safety-critical installations.
3. Environmentally Friendly Design with Long Service Life and Low Maintenance
Beyond fire safety, LSZH flame retardant cables offer significant environmental and lifecycle benefits. Halogen-free materials produce fewer harmful substances during manufacturing, use, and disposal, supporting global trends toward green buildings and sustainable development. At the same time, modern LSZH compounds provide excellent mechanical strength, flexibility, and resistance to aging, moisture, and environmental stress. These characteristics ensure stable electrical performance over long-term operation and reduce the likelihood of premature cable failure. As a result, LSZH cables deliver a long service life, reduced maintenance requirements, and lower total cost of ownership, making them a future-ready and cost-effective solution for modern infrastructure projects.
