ELECTREN DEVELOPMENTS
Overhead
Contact Line:
We design and develop all the E-350 for high speed overhead contact
lines, including parts, structures and systems.
Automated
Control:
Development of ART10 Control System for 1x25
​​
KV / 2x 25 KV High
Speed Substations .
Remote control:
Development and integration of remote power, MAS system, for
railways in 61-850-101 and 104. Four remote control systems implemented
at ADIF. Allows control of safety and flexibility during automatic cutoff
operations to be performed in scheduled or corrective maintenance
operations.
Mobile traction
substations:
Development of dual voltage 600/1500V DC Mobile Substations for trams
and narrow gauge railways.
Modular traction
substations:
Mobile substations on platforms evolve into the concept of modularity,
providing advantages in assembly, work economics, deadlines, reducing
environmental impacts in construction and infinite assembly and scalability
possibilities. Our solution is called “motracs”.
Electrical safety:
SENCO is an integrated development of the electrical interlocking concept,
which improves safety in high and medium voltage electrical installations.
Power supply
for containerized
railway transport:
The GERCO (“Onboard Container Refrigeration Generation”) project
allows cooling of containers during rail transport, as an appropriate and
optimal solution to ensure the cold chain and optimize transport times.
Research:
TRADIS Chair in collaboration with the University Carlos III of
Madrid, for research into the development of an Electrical Dimensioning
Platform for railway lines: Catenary, Substations and Power Distribution.
HIGH SPEED
ELECTREN, in collaboration with other companies and
bodies in the industry, has developed the technology for the
E350 high speed railway electrification system. This system
is based on the 2 x 25kV 50Hz type power supply, in which
the traction units receive voltage through the catenary
(+25kV), the return line and a negative feeder (-25kV).
It allows for more efficient power transmission as this is high
voltage (50kV) and decreases the return current through
the return cable. It thereby increases the return current
through the -25 kV cable, and reduces the effects of
diverted return currents causing interference in
communications and signalling systems in conventional 3kV
DC electrification systems nearby.
Therefore, the main advantages of this catenary are
efficient power transmission, decreased effects on nearby
systems, easy adjustability, interchangeable parts, reliability,
optimal interaction between the pantograph and the
catenary, and European interoperability according to TSI
2008.
ELECTREN HAS DEVELOPED
THE TECHNOLOGY FOR THE
E350 HIGH SPEED RAILWAY
ELECTRIFICATION SYSTEM.
