Increasing Adoption of Electrification of Railways Drives Growth of Traction Transformers Market

Global traction transformers market was valued at $815 million in 2024 and is anticipated to grow at a CAGR of 4.4% during the forecast period (2025-2035). Industry growth is driven by the increasing adoption of electrification of railways, increasing demand for energy-efficient and lightweight transformers with growing investment in infrastructure advancement and high-speed rail networks driving the market growth. According to the International Energy Agency, (IEA), in 2023, the annual metal consumption for transformers, distribution grids, and power transmission lines will increase by almost 50.0% in 2022–2030. Grain-oriented electrical steel (GOES) is needed to manufacture power transformers, and the US, China, Japan, Korea, and Russia account for over 85.0% of the global 3.8 Mt annual manufacturing capacity. Traction substations are a common element of electric railway systems.

Integration of Transformers in Powering Train Systems and Electrical Infrastructure

• Transformers in substations are responsible for transforming electrical electricity from power utilities into a format that can power a train system via third rails or overhead wires.
• The finest transformers for this sector must operate safely and effectively while withstanding electrical stressors, temperature changes, and mechanical vibrations. 
• For the train's traction system, traction transformers translate high-voltage AC electricity up to 25 kV into lower voltage levels of up to 1 kV. 
• On the other hand, in power transmission and distribution systems, standard transformers can step up or down voltage levels of up to 765 kV.

Recent Developments

• In September 2022, A revolutionary plug-and-play, oil-free traction transformer was introduced by Hitachi Energy. The built-in cooling system, the RESIBLOC® Rail dry-type traction transformer lowers CO2 emissions and overall running expenses while boosting energy efficiency. An innovative technique for dry-type on-board traction transformers is this plug-and-play solution. The advantages of dry-type transformers are maintained while Hitachi Energy drastically lowers installation complexity for train makers by incorporating an effective cooling system.
• In February 2022, Mitsubishi Electric delivered traction systems for the first time to SNCF Voyageurs, a French national railway operator. After a positive assessment of prototype main transformers produced for a Z2N commuter train and a T4 tram train operating in Paris, SNCF Voyageurs and CAF chose Mitsubishi Electric as the provider. Mitsubishi Electric hopes to bolster its transportation systems business.
