Electric Locomotive

Electric locomotive is most preferred type of locomotive for both passenger and goods transportation.They are in application due to its significant fuel saving advantage. 3 Phase Traction Transformer of the electric locomotive has mineral oil as the cooling medium. The Propulsion system consisting of main power convertor and auxiliary convertor has water glycol coolant as the cooling medium. Heat Losses generated by traction transformer and propulsion system needs to be dissipated by cooling system. Apollo is the first Indian company to develop indigenous cooling system for electric locomotives. Optimum design of the water coolant aluminum heat exchanger and transformer oil cooler are required to be done to achieve the required cooling performance. We are the major supplier for locomotive cooling system to Indian railways. Compact Aluminum heat exchanger design helps to make the overall cooling system very effective. We provide cooling solutions for traction transformer, vehicle control unit, converter system & break compressor.
