High-rise buildings present unique fire safety challenges due to their vertical structure, high occupant density, and complex evacuation requirements.
During a fire incident, maintaining power and signal continuity is essential to support evacuation, fire-fighting operations, and life-safety systems.
Fire resistant cables are specifically designed to maintain circuit integrity under fire conditions, ensuring critical systems continue operating when they are most needed.
In high-rise buildings, electrical systems support a wide range of safety-critical functions.
Cable failure during a fire can lead to:
Loss of fire alarm and detection systems
Failure of emergency lighting and exit signage
Elevator control malfunction
Smoke extraction and pressurization system shutdown
Fire resistant cables help ensure these systems remain operational long enough to allow safe evacuation and emergency response.
Fire resistant cables are commonly specified for:
Fire alarm and detection systems
Emergency lighting and escape route signage
Firefighter communication systems
Smoke control and ventilation systems
Emergency power supply circuits
Elevator and lift control systems
These systems are essential for both occupant safety and fire-fighting coordination.
| Feature | Fire Resistant Cables | Flame Retardant Cables |
|---|---|---|
| Maintain circuit integrity during fire | ✔ | ✖ |
| Support evacuation systems | ✔ | Limited |
| Suitable for vertical safety systems | ✔ | Limited |
| Main function | Fire survival | Fire spread reduction |
Flame retardant cables can slow the spread of fire, but only fire resistant cables are designed to continue functioning during direct fire exposure.
BS 6387 CWZ fire resistant cables are tested to withstand:
C – Fire exposure at 950°C
W – Fire with water spray from sprinklers
Z – Fire with mechanical shock
High-rise fire scenarios often involve sprinkler activation, falling debris, and mechanical impact, making CWZ-rated cables suitable for real-world conditions.
Recommended fire resistant cable construction includes:
Copper conductors for stable electrical performance
Mica tape insulation for fire survival
XLPE insulation layer
LSZH inner and outer sheaths to reduce smoke and toxic gases
Optional armour for risers and service shafts
This construction helps protect both occupants and emergency responders.
Use fire-rated cable supports and fixings
Ensure correct installation in vertical risers
Integrate with fire-stopping systems at floor penetrations
Maintain separation from non-essential power cables
Proper installation is critical to achieving certified fire performance on site.
Fire resistant cables are widely used in:
Residential high-rise buildings
Commercial office towers
Mixed-use developments
Hotels and serviced apartments
Similar vertical safety requirements can also be found in airport infrastructure and data centers, where continuous operation of critical systems is required.
