In modern buildings and industrial facilities, wires and cables function like the "nervous system" of a structure, carrying the vital missions of power transmission and signal control. However, in the event of a fire, ordinary wires and cables can become "accelerating channels" for the spread of flames. As a professional manufacturer of wires and cables, we deeply understand the importance of fire safety. Here, we provide a comprehensive analysis of the technical advantages and application value of fire-resistant wires and cables.
1. What are Fire-Resistant Wires and Cables?
Fire-resistant wires and cables are special cables that can maintain circuit integrity and continue to operate safely for a specified period under flame conditions. They not only possess flame-retardant properties but also maintain circuit continuity under high temperatures or direct flame exposure, buying precious time for the emergency operation of critical equipment, personnel evacuation, and firefighting and rescue operations.
2. Core Technical Features
1). Multi-Layer Protective Structure
Conductor: High-purity oxygen-free copper ensures stable conductivity.
Insulation Layer: Special fire-resistant mica tape or ceramifiable polymer, forming a robust protective shell under high temperatures.
Sheath: Low-smoke zero-halogen (LSZH) flame-retardant material, inhibiting flame propagation and reducing toxic smoke.
2). Exceptional Performance Indicators
Fire Resistance Duration: Maintains circuit integrity for 90-180 minutes in flames of 750-950°C.
Low-Smoke Characteristics: Smoke density during combustion is more than 70% below standard values, improving visibility.
Halogen-Free & Eco-Friendly: Free of halogens, does not release corrosive toxic gases when exposed to fire.
Mechanical Impact Resistance: Withstands water spray and mechanical vibration even after fire resistance testing.
3. Primary Application Areas
Lifeline Projects: Hospitals, schools, nursing homes, and other densely populated places.
Critical Infrastructure: Subways, tunnels, airports, data centers.
Industrial Safety: Chemical plants, power plants, mines, and other high-risk environments.
High-Rise Buildings: Power supply lines for fire protection systems, emergency lighting, smoke exhaust equipment.
Cultural Heritage Protection: Museums, libraries, historical buildings.

5. Selection Guide
When choosing fire-resistant wires and cables, please consider:
Clearly define the required fire resistance rating (e.g., highest C-W-Z classification per BS6387).
Confirm applicable national standards (e.g., GB/T 19666).
Account for environmental factors (humidity, chemical corrosion, etc.).
Select a manufacturer with a comprehensive quality assurance system.
Conclusion
Fire-resistant wires and cables are not ordinary construction materials; they are an essential component of the safety system. Investing in high-quality fire-resistant cables during building design and renovation is the most practical safeguard for life and property safety.
