Rio de Janeiro Metro, Line 4

Characteristics

An important construction for the city of Rio de Janeiro, the Metro line 4 started operating in 2016 and was designed to transport more than 300 thousand people a day, removing from the streets about 2 thousand vehicles per hour/peak in each direction of the axis Barra da Tijuca-Zona Sul. The line has approximately 16 kilometers of tracks and 6 passenger stations.

TSEA implemented São Conrado Primary Substation and the 12 Auxiliary Substations responsible for power supplying to the new line and the various auxiliary equipment located in the Tunnels, Passenger Stations and Maintenance and Maneuvering Yards, with special emphasis on the gas insulation technology (GIS: Gas Insulated Switchgear) of São Conrado Primary Substation, ensuring economy, safety and reliability to the Metro operations.

Technical Characteristics
Number of Stations 6
Max Speed 80 km/h
Headway 4 min
Primary Energy Gas Insulated Switchgear (GIS)
138 kV / 22 kV / 90 MVA
Auxiliary Energy 440 / 220 / 127 Vca -
Between 112.5 and 750 kVA per substation

São Paulo Metro, Extension of Line 5

Characteristics

The project connects Largo Treze, in the neighborhood of Santo Amaro, to Chácara Klabin, totaling an extension of 19.9 km, 17 stations and 02 depots.

TSEA’s project is composed of 01 Primary High Voltage Substation, 14 4MW Rectifier Substations, 12 Low Voltage Auxiliary Substations, 11.5 km of 1500 VDC rigid catenaries, conventional catenaries, and also the Escape Route Signaling System. TSEA’s scope encompasses the development of the executive design, equipment supply, electromechanical assembly, factory tests, training, commissioning tests, spares and assisted operation.

With the commercial start-up of the Adolfo Pinheiro – Chácara Klabin section, Line 5 – Lilac has an estimated demand forecast of 781,300 passengers/day with 34 trains operating at peak hours.
