The traction transformers market has experienced considerable growth over the last five years, as these transformers are considered to be substitutes for fossil fuel based traction systems. Shift to traction transformers in order to address environmental concerns due to their inherent properties including higher power to weight ratio, lower power loss at higher altitudes, low running cost of locomotives, less noise pollution and lack of dependence of crude oil, is expected to drive the market over the forecast period. Significant government funding and liberalization of rail transport market are other factors expected to favorably impact market growth.
The Power Electronic Traction Transformer (PETT) is referred to as the “fourth revolution” in the traction technology as the market has gradually moved towards PETT which uses power electric components instead of conventional components. Need for special considerations owing to vibration problems and space availability is expected to pose a challenge to market growth.
Traction transformers are used in high speed trains and electric locomotives where a very high power rating of over 5.5 MVA is required. The traction transformers market can be segmented on the basis of product, rolling stock and voltage network. Based on voltage network, the market can be bifurcated into AC (Alternative Current Systems) and DC (Direct Current Systems). These transformers are mainly used in four types of rolling stocks, namely Electric Multiple Units (EMUs), high-speed trains, trams and electric locomotives. The three primary types of these transformers are tap-changing, tapped, and rectifier transformers.
ABB has been in the traction transformers manufacturing business since over a century. ABB transformers have accumulated substantial running hours worldwide. Siemens develops and produces traction transformers for rolling stock applications of customer specific requirements, ratings and voltage levels. Key players in the traction transformers market include Daiichi Electric, Mitsubishi Electric, Siemens, ABB, and Alstom.
