Siemens to Electrify Lima Metro Line 2 and 4
Siemens has contracted with Ansaldo STS to electrify Lima Metro Line 2 and a segment of Line 4. The new lines will be a welcome addition to the citys mass transit network, connecting areas of the city and the international airport. Passenger service will be rolled out from 2017, with other sections to be completed by 2021.
The project is being hailed as an environmental triumph, with 80% of the electricity to power the lines coming from hydroelectric power plants. The 27km double-track Line 2 will connect the eastern district of Ate to Callao in the west. While these works are being undertaken, the line will be extended to the citys airport, which will later become part of Line 4.
The project will require six feeder stations (60 kV/20kV), two 20 kV cable distribution rings, 37 station supplies and 21 rectifier substations (1.5kV, DC), as well as the SCADA (supervisory control and data acquisition) system for the electrical systems.
Siemens will fit the type series 8DN8 gas-insulated switchgear is specially designed for space-saving system configurations and features a low dead load, making it economically efficient. The equipment is also noise-efficient and emits low field emission (EMC), which makes it ideal for residential areas and city centres.
