Siemens Ltd. has bagged an order worth approximately $12.3 million from Indian Railways' Diesel Locomotive Works (DLW), Varanasi. The company will design, supply and install 40 Alternating Current (AC) Traction Systems for dual-cab high horsepower diesel engine locomotives. The AC Traction Systems will be produced at Siemens' Nashik Factory. The systems have been developed based on the state-of-the-art Insulated Gate Bipolar Transistors (IGBTs) technology. The main benefit of IGBTs over Gate Turn-off thyristors (GTOs) is that it reduces the current required, and therefore the heat generated, giving smaller and lighter units.
Tilak Raj Seth, Executive Vice-President and CEO, Mobility Division, Siemens Ltd. said that the introduction of IGBTs has yielded strong efficiency gains in electric drive technology. The project showcases Siemens' partnership with the Indian Railways as it combines innovation with responsibility, bringing together the combined expertise of its teams.
