Documentation
In order to
satisfy all the needs required by the worldwide railroad market
in terms of transparencies, a large number of technologies are necessary
:
Diversity
of the rolling stocks
According to
their use, several categories of rolling stocks are to be considered
:
HST
(High Speed Trains)
Locomotives for Freight or Passengers
Intercity Trains
Street cars and Métros, Urban transportation
Diversity
of the glazings
Each family
of rolling stock requires several types of glazings, depending on
their functions :
Light
covers and Destination signs
Windshields and front windows
Side windows for cab and passengers cars
Door windows
Electro transparencies for interiors
Design
adapted to the needs
It is understandible
that each product has to be defined precisely in relation with the
industrial standards, technical specifications, size, weight etc…
SAINT-GOBAIN
SULLY builds its strength on the technical competence of its Design
team and R&D department as well.
Its cumulated
experience and their worldwide vision allow SAINT-GOBAIN SULLY to
fullfill all the needs of its customers around the world.
Development
and certification
SAINT-GOBAIN
SULLY takes part to the development of new programs as soon as possible
at the beginning of the train design, in close relationship with
its customer.
A very documented technical offer is proposed to the Engineering
people supported by the test results that are requested by the program.
Among them,
one can find :
- Résistance to the impacts, from gravels to the most energetic
impacts
- Weathering
- De-icing and de-misting of the windshields
- Spectrophotometry and Colorimetry to comply with the signals
spectrum
Tests procedures
are finalized by the certification Department in relation with the
Customer teams.
Interfaces
The installation
of the glazings on the structure is very important and SAINT-GOBAIN
SULLY takes great care to propose a panel of approved solutions
adapted to the type of window and the type of train :
- Direct bonding on to structure
- Rubber gaskets
- Molded gaskets
- Complete framed window in relationship with the frame makers
- Electrical interfaces, thermostat, sensor, ...
The goals of
our teams are to keep a high degree of safety, maintain a high life
time and minimise the global costs and replacement leadtimes.
Extra features
The rolling
stocks are more and more demanding of new functionnalities. It is
compulsory that Saint-Gobain Sully can propose proven and innovating
solutions.
- Lessen solar factor without degrading light tranmission in order
to lessen costs of cars'air condiditionning.
- Develop noise attenuation devices for more confort inside the
passengers cars.
- Increase the impact resistance of the products for a better
protection of the drivers.
- Propose anti-spall technologies in case of front impacts.
- Insure a clearer vision through the windshields in case of rain
Saint-Gobain
Sully can take advantage of the developments which are carried out
by its mother Company, SAINT-GOBAIN SEKURIT, a worldwide specialist
of the cars windows.
Documentation
The following
documents shows the impact effects of some projectiles on a windshield,
under usual conditions.
Those documents
have been recorded in our tests lab (air canon) and are usually
attached to our technical reports during the development period
of the program.
