Product Overview
Flame Retardant Fire Resistant Cable is a special power and control wire with dual safety properties. It combine flame retardant self-extinguishing ability and fire-resistant circuit integrity performance.
Fire resistant flame retardant wire and LSZH fire resistant cable are high-value SEO extension terms. These specialized cables differ greatly from ordinary PVC electrical wires.
Ordinary cables burn fast and spread flames freely. They lose power conduction once fire happens.
Flame Retardant Fire Resistant Cable stop flame spreading actively. It keep normal circuit operation for a fixed time under high-temperature fire conditions.
This safety feature make it essential for fire emergency systems and high-risk building electrical projects.
Core Cable Classification & Types
Flame Retardant Focused Cables
These cables follow IEC 60332 test standards. The outer sheath use flame retardant polymer materials.
They cannot sustain power supply in fire. But they prevent fire spread along cable lines effectively.
Fire Resistant Focused Cables
Fire resistant cables adopt mica tape wrapping structure. The core layer resist high temperature flame erosion.
It maintain circuit integrity during fire. It support emergency power supply for rescue equipment.
Dual Performance Composite Cables
Flame Retardant Fire Resistant Cable integrate both functions. It have self-extinguishing and fire-resistant working ability.
This composite type meet strict safety standards for public buildings and industrial facilities.
Fire Performance Standard Comparison
International certification standards define clear performance differences. The table below shows verified test data of mainstream cable safety grades.
All data come from IEC and BS official test specifications and third-party detection reports.
Cable Type | Test Standard | Fire Resistance Duration | Max Flame Temperature | Circuit Integrity |
Ordinary Flame Retardant Cable | IEC 60332-3 | No sustained resistance | 450°C | Not specified |
Standard Fire Resistant Cable | IEC 60331 | 90 minutes | 750°C | Fully maintained |
High-grade BS 6387 CZ Cable | BS 6387 | 180 minutes | 950°C | Shock & heat resistant |
Flame Retardant Fire Resistant Cable | IEC 60331 + 60332 | 120 minutes | 850°C | Stable integrity |
Dual-function flame retardant fire resistant cable balance safety and cost. It fit most commercial and industrial fire protection projects.
BS 6387 high-grade cables provide extreme fire resistance. It used for core fire emergency circuits only.
Key Structural & Safety Features
Special mica tape insulation layer is the core fire-resistant structure. It block high temperature from damaging internal copper conductors.
Modified LSZH outer sheath support flame retardant performance. It produce low smoke and non-toxic gas during burning.
The cable structure resist external impact and extrusion. It keep stable performance in complex installation environments.
Long-term working temperature reach 90°C. It have good aging resistance for long service life.
Common Industrial Applications
Public Building Fire Emergency Systems
Shopping malls, hospitals and office buildings use these cables. They supply power for fire alarms and emergency lighting.
Continuous power supply ensure safe evacuation during fire accidents.
Tunnel & Metro Engineering
Closed traffic tunnels need high safety cables. Low smoke and flame retardant features avoid smoke diffusion and secondary hazards.
Industrial High-risk Workshops
Chemical and power plant workshops adopt dual-performance cables. It reduce fire spread risk in high-temperature working areas.
Basic Selection Guidelines
Common indoor ordinary areas choose standard dual-grade cables. It meet daily fire safety needs.
Closed crowded spaces must pick LSZH flame retardant fire resistant cable. Toxic smoke is strictly restricted.
Core emergency circuits need BS 6387 high-grade models for longer fire resistance time.
Industry FAQs
Q1: What is Flame Retardant Fire Resistant Cable?
It is a dual-function safety cable. It stops flame spreading via flame retardant material, and maintains circuit integrity for 90–120 minutes under fire conditions.
Q2: What is the difference between flame retardant and fire resistant cables?
Flame retardant cables only stop fire spread. Fire resistant cables keep power supply in fire. Dual-performance cables own both functions.
Q3: What standard tests apply to these cables?
They pass IEC 60331 fire resistance test and IEC 60332 flame retardant test. High-end models meet BS 6387 extreme fire safety standards.
Q4: Where must these cables be installed?
Fire emergency circuits, tunnel power systems, public building emergency lighting and high-risk industrial workshop wiring require these safety cables.
