The state-owned Delhi Metro Rail Corporation Limited (DMRC) serves India’s National Capital Region and is the national benchmark for on-time project execution and efficiency. Electrified via 25-kilovolt (kV), 50-hertz (Hz) overhead catenaries, DMRC oversees 213 kilometers of track and 148 street-level, elevated and underground stations, serving 2.661 million passengers each day.
ABB has delivered an array of products and systems for DMRC over the years, including traction transformers for 614 high-capacity metro trains manufactured by Bombardier. For these metro cars ABB developed an integrated, under-frame traction transformer with a silicon oil cooler unit and accessories that ensure it will provide reliable service despite heavy daily use. The ABB traction solution also guarantees low-noise levels.
The initial traction units for this project were made in Switzerland, and the remainder manufactured locally at ABB’s state-of-the-art transformer facility in Vadodara, India, providing the customer with high-quality, locally-built products.
Deliveries were completed in 2012 and in 2015 Bombardier received new orders for additional train sets which will increase the DMRC metro fleet from 614 to 776 units – all of them equipped with ABB traction transformers.
