Adjustable waterproof cable and pipe transit system
AFIMES
The system makes it possible to treat crossings of cables in floor, roof and ends to avoid the waves of pressures in the trains at high speed, like ensuring a protection cuts fire and acoustics in all the other trains.
System MCT Brattberg equips the trains at high speed, the regional trains, the subways, the trams and the engines of freight.
All the trains circulating in tunnel must be able to face a fire on board. They are built to resist to allow the evacuation of the passengers sufficiently a long time. The nontoxic choice of materials is paramount.
Eurostar (Paris-London) is the first TGV equipped with MCT. A very thorough reflection on the structure of construction and its fire resistance led to the choice of the MCT: in the event of fire on board, the train must arise from the tunnel 20 minutes after while having safeguarded its passengers. All the other trains are now built on this philosophy.
Moreover, the performances of sealing of the MCT improve auditive comfort of the passengers by reducing the impact of the waves of pressure generated by the entries in tunnel at high speed.
The manufacturers of rolling stocks make reliable their trains by industrializing their processes of assembly of the electrical looms. MCT is integrated during the breadboard construction. The beams can then be gone up with the connector industry.
