Flame-Retardant Cables

In fire scenarios, standard cables tend to accelerate fire spread, while flame-retardant cables can effectively suppress flame propagation, gaining valuable time for personnel evacuation and firefighting operations. Manufactured with high-performance flame-retardant materials and specialized structural design, these cables maintain circuit safety under high-temperature open-flame conditions, preventing secondary disasters caused by cable combustion.

I. Core Characteristics of Flame-Retardant Cables

1. Flame Retardancy & Fire Spread SuppressionAdopt Low Smoke Zero Halogen (LSZH) flame-retardant materials, which do not emit large volumes of toxic gases or dense smoke when exposed to fire, reducing the risk of personnel suffocation.The outer sheath of the cable features self-extinguishing properties, ceasing combustion shortly after the ignition source is removed and preventing flame spread along the cable route.

2. Low Smoke & Low Toxicity, Enhancing Evacuation SafetyUnlike traditional Polyvinyl Chloride (PVC) cables that produce heavy black smoke and corrosive gases when burning, LSZH flame-retardant cables drastically reduce smoke density, ensuring visibility in fire sites to facilitate personnel evacuation and firefighting efforts.Only trace amounts of non-toxic gases are released during combustion, complying with the international environmental standards IEC 60754 and EN 50267.

3. High Temperature Resistance, Ensuring Emergency Power Supply ContinuityThe cable insulation layer maintains stable performance even under high-temperature exposure, guaranteeing uninterrupted power supply for critical equipment such as fire pumps, emergency lighting systems, and smoke exhaust systems during fires.Suitable for high-heat environments including high-temperature workshops, substations, and data centers with stringent heat resistance requirements.

II. Typical Application Scenarios

1. High-Rise Buildings & Commercial ComplexesEffectively block vertical fire spread in cable shafts, mitigating the fire "chimney effect".Applicable to crowded places such as shopping malls, hotels, and office buildings, meeting fire acceptance code requirements.

2. Metros, Tunnels & Underground SpacesTailored for underground environments with poor ventilation and slow smoke dissipation, the low-smoke characteristic significantly improves personnel survival chances during evacuation.Suitable for enclosed scenarios including metro power supply systems, tunnel lighting, and underground parking lots.

3. Petrochemical & Industrial PlantsIn petrochemical and oil refinery facilities with flammable and explosive gas hazards, these cables reduce the risk of ignition caused by electric sparks, meeting explosion-proof standards.High-temperature resistant variants are suitable for high-heat industrial areas such as metallurgy and glass manufacturing, ensuring long-term stable equipment operation.

4. Hospitals, Schools & Public FacilitiesIdeal for critical power supply areas in hospitals such as ICUs and operating rooms, preventing medical treatment disruptions due to power outages during fires.Improve the overall fire safety level of densely populated public facilities including schools and gymnasiums.

III. Selection Guidelines

1. General Flame-Retardant Type (FR)：Suitable for general building power distribution systems, meeting basic fire protection needs.

2. LSZH Flame-Retardant Type：Ideal for scenarios with strict smoke and toxicity control requirements, such as metros, hospitals, and data centers.

3. Fire-Resistant & Flame-Retardant Composite Type (FR-CI)：Designed for critical circuits requiring continuous power supply during fires, including fire protection systems and emergency power supplies.
