TRADIS Chair in collaboration with the University Carlos III of Research: Madrid, for research into the development of an Electrical Dimensioning Platform for railway lines: Catenary, Substations and Power Distribution. HIGHSPEED

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.
