Siemens Ltd. on Friday announced receiving of an order worth Rs. 98 crore from Diesel Locomotive Works (DLW) to design, supply and install 48 Alternating Current (AC) Traction systems for Dual Cab High Horsepower Diesel Engine locomotive for Indian Railways.
The AC Traction systems will be produced at Nashik Factory of Siemens Limited. The systems have been developed based on the state of art Insulated Gate Bipolar Transistors (IGBTs) technologies.
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.
In addition, Siemens was also awarded orders worth Rs. 166 crore for supply of propulsion sets for Freight Locomotives and Rs. 55 crore for supply of propulsion sets for Passenger Locomotives. Read more
