This catenary free system which enables it to preserve the aesthetics of the city reduces the rail system s footprint by eliminating poles while optimizing safety and operational reliability.
Aps ground level power supply system.
Opening in december 2003 the bordeaux france tramway became the first second generation tramway to use the aps or alimentation par sol ground power road surface power supply system.
In addition the ground level power supply system which has been in use since 2003 in bordeaux is now completely reliable thanks to feedback on more than 7 million km travelled.
One of the most innovative aspects of the bordeaux tram system is the complete lack of overhead cables for significant portions of the network.
The aps ground level power supply system has been chosen by transport companies in angers bordeaux brasilia dubai orleans and reims.
The solution will be installed on the new ten kilometre long halic golden horn line thereby rendering it entirely catenary free.
Aps system stations one of the cutting edge technologies developed for the dubai citadis tramway is its aps ground level power supply.
Alstom will supply a full aps ground level power supply solution for the istanbul metropolitan municipality 1.
Ground level power supply or in french aps alimentation par.
Alstom s aps consists of a conduit flush with the ground on top of which are 8 metre long contact strips alternating with 3 metre long insulated segments.
Alstom will design and supply the continuous traction power transmission.
The solution will be installed on the new ten kilometre long halic golden horn line thereby rendering it entirely catenary free.
As with many other cities bordeaux had previously used trams its former first generation system closed in 1958.
Inside this conduit are the supply cables and an antenna.
The bordeaux tramway and aps.
There is a power supply box adjacent to every other insulated segment that feeds the adjacent contact strips.
This is thanks to the use of a technique that was conceived and perfected for the bordeaux project first by spie innorail then by alstom.
Ground level power supply also known as surface current collection and alimentation par le sol aps which literally means feeding via the ground is a modern method of third rail electrical pick up for street trams instead of more common overhead lines thus it is one of the methods that could allow construction of catenary free light rail system it was invented for the bordeaux tramway.
