OHLA and its subsidiary EyM, which specializes in electrical installations, have been awarded the contract for the electrification and power supply systems for the entire route of the Alcalá de Guadaíra tramway (Seville). The work, which has been awarded by the Junta de Andalucía for a value of about 30 million euros, is part of the last contracts for the commissioning of the tramway.
The scope of the project includes the electrification of the 12.5 km route necessary to put into service the entire Alcalá de Guadaíra tramway line, from the Pablo de Olavide to Montecarmelo stations.
Specifically, the actions include the power supply of the tramway line by means of a 66 kV three-phase double-circuit subway power line, the installation of five traction substations along the route, as well as the construction of transformation centers for stations and stops.
A 20 kV power distribution network will also be deployed to connect the substations and transformer stations, as well as a power remote control to monitor and control the facilities and ensure traction to the trains and auxiliary services. The works also include the installation of the 750 V catenary distribution network and a low voltage network to supply the auxiliary equipment.
