Especially in buildings with public traffic, tunnels as department stores, airports, hospitals and other public places security is top priority.
The emergency power supply in accordance with regional building regulations is generally required.
 In the event of fire, the functional integrity of the emergency power supply must be guaranteed for a specific period of time. 
This ensures that electric devices, such asemergency lighting, lifts, smoke extractors, alarms, junction boxes etc. remain operational for 30, 60, 90 or 120 minutes and that people can leave the building and rescue services can work in case of fire.

In addition to these requirements electrical installation systems must fulfi ll especially the electrical parameters with all components

Delvalle offers a full range of fire resistant junction boxes, suitable for use within confined spaces and working environments such as road and rail & road tunnels.

As these environments can be extremely corrosive due to heavy pollution, cleaning, road debris, smoke and heat generated in the event of a fire, it is critical that installed electrical equipment is compliant with European & International standards with respect to fire resistance and flame retardancy.

Fire rated enclosures are prepared for a high humidity concentration or a very dry environment, with the guarantee that the electrical components will continue operating after many years.

Fire rated enclosures are designed to meet the specifications for building fire safety, over ground and underground, rail applications, road tunnels and other public places where electrical power supply, emergency lighting and public address systems are required to be fully operational in the event of a fire.
