ABB Switzerland modernizes SBB locomotives
ABB has received a follow-up order from SBB to modernize locomotives with traction converters. This significantly increases the energy efficiency of the locomotives.
As part of the new order, 18 SBB locomotives of the latest generation will be modernized with traction converters from ABB, according to a press release. The Zurich-based and internationally active technology group has its Swiss headquarters in Baden and manufactures traction converters in its plant in Turgi AG. In 2014, ABB received an order from SBB to modernize locomotives with traction converters. With the follow-up order now received, ABB will modernize the entire Re 460 fleet. These are the locomotives of most intercity trains.
SBB is implementing a modernization program for the fleet, which will extend its service life by 20 years. The new traction converters and additional technical measures can save around 30 gigawatt hours of energy annually, "that's five gigawatt hours more than originally expected," says ABB. According to the report, these energy savings correspond to the “average electricity consumption of 10,000 Swiss households”. For this purpose, the power electronics based on the technology of the 90s are being replaced by energy-efficient, water-cooled IGBT traction converters (insulated-gate bipolar transistor). This retrofit and cooling systems operated with water instead of oil can reduce energy consumption.
"We are pleased that we are a partner in this major modernization project in the Swiss home market with our drive solution and that we are working closely with SBB to ensure that the vehicles continue to be operated in an energy-efficient manner," said Robert Itschner, Country Managing Director at ABB Switzerland.
