Siemens Ltd today said it has won an order worth Rs 83 crore from the Indian Railways' Diesel Locomotive Works (DLW).
The order is to design, supply and install 40 alternating current (AC) traction systems for dual-cab high horsepower diesel engine locomotives, Siemens Ltd said in a statement.
"The advent of IGBTs (insulated-gate bipolar transistor) has yielded strong efficiency gains in electric drive technology," said Tilak Raj Seth, Executive Vice-President and CEO, Mobility Division, Siemens Ltd.
The AC traction Systems will be produced at Nashik Factory of Siemens. The systems have been developed based on the state-of-the-art IGBTs technology.
The principle 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.
