Cables represent less than 0,5 percent of a building's cost. Nevertheless they play an important role in guaranteeing public safety and protecting vital infrastructure; in case of fire, they can allow an efficient evacuation and help fire-fighting crews in their efforts. Indeed, a number of infernos in Europe and around the world have recently emphasized the importance of fire safety cables.
Nexans cables are divided into two different categories :
- Fire Reaction: cables are classified according to their thermal behaviour in case of fire; i.e. amount of heat released, quantity and density of smoke, acidity, droplets…
In this field, Nexans has taken a strong position in promoting Halogen Free Fire Reaction cables under the brand ALSECURE®
- Fire Resistance: cables are classified according to their ability to continue to operate in a fire; our Fire Resistant cables are grouped under the brand ALSECURE® PLUS
Benefits
- a wide choice of low-voltage energy, data, control and communication cables for residential, industrial and public buildings
- superior reaction to fire, thus limiting fire growth in sensitive public areas such as subways, tunnels and high-rises
- exceptional resistance to fire, allowing security systems like video surveillance, smoke evacuation, security alarms to keep on operating during a fire
- low smoke emission due to Halogen Free insulation and jacketing materials, meaning better visibility during evacuation and fire-fighting operations
- minimal corrosive damage to equipment and steel/concrete structures, thus reducing expensive replacement, cleaning and secondary pollution
A number of infernos
Tragic fires in Düsseldorf airport, London's Kings Cross station, Moscow University, the Mont blanc tunnel, and the Kaprun funicular in Austria have dramatically underscored the risk of fire propagation. Flames, opaque smoke, noxious fumes and corrosive gases can sometimes spread at high velocity beyond the fire area via the cable network.
