Electrén, high speed leader |
|
Electrén has worked with other companies and bodies in the sector on developing rail electrification system technology for AE350 high speed rail.
This system is based on 2 x 25 kV 50 Hz type power supply, in which the traction units are powered via the catenary (+25kV), a grounded return line and a negative feeder (-25kV).
The main advantages of this system are:
- Ease of control.
- Pieces which are interchangeable with other installed systems, simplifying maintenance management.
- Reliability.
- Optimum interaction between catenary and pantograph.
- Complies with European interoperability regulations.

This is a summary of technical features of the AE350 catenary.
- Simple, polygonal, vertical, and braced catenary with compensator.
- Design speed: 350km/h+10%.
- Auxiliary messenger cable (Y−shaped catenary hanger).
- Aluminum tubular cantilevers.
- Contact wire: 150 mm2 (CuMg0.5), mechanical tension: 3,150 Kg.
- Messenger cable: Cu 95 mm2, mechanical tension: 1.575 Kg.
- Auxiliary messenger cable: Cu 35 mm2, mechanical tension: 315 Kg.
- Equipotential catenary hangers with Cu 25 mm2 loops.
