ROLLING STOCK TRACTION TRANSFORMER MARKET OVERVIEW

Global rolling stock traction transformer market size is predicted to reach USD 3.2 billion by 2032 from USD 2 billion in 2023, registering a CAGR of 5.3% during the forecast period.

A vital part of electrifying railroad networks is a rolling stock traction transformer. It is essential in providing the proper voltage and frequency to run the traction motors of electric trains when converting electrical power from the grid or an overhead catenary system. A traction transformer's main job is to reduce the high voltage from the power supply—which is usually between 15 and 25 kV—to the voltage that the traction motors need, which is usually between 600 and 3 kV. To satisfy the unique needs of the train's propulsion system, this change is required.

COVID-19 IMPACT

COVID-19 Adverse Effected in Project Delays and the Financial Challenges Havocked the Market Growth 

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to market’s growth and demand returning to pre-pandemic levels.

The economic aftermath of the epidemic, lockdowns, travel restrictions, and budgetary constraints may have resulted in delays or postponements of several rail electrification projects. This might thus have an impact on the need for rolling stock traction transformers. The pandemic may have caused budget cuts for manufacturers, suppliers, and railway operators, which would have impacted investments in electrification projects and new train equipment.

LATEST TRENDS

High Speed Rail and Urban Transit Projects with Advanced Technologies to Tumble Up the Market Shares

Urban transportation systems and high-speed rail are in constant demand. In these projects, traction transformers are essential, and manufacturers can concentrate on creating transformers that satisfy the particular needs of urban and high-speed rail applications.

ROLLING STOCK TRACTION TRANSFORMER MARKET SEGMENTATION

By Type

Based on type the global market can be categorized into core type traction transformer and shell type traction transformer.

  • Core Type Traction Transformer: The main and secondary windings of a core-type transformer encircle the magnetic core, which is made of laminated iron or steel. Usually, the windings are coiled around the core's limbs, or legs. Due to its small size and good magnetic coupling between the windings, it is often more affordable at power ratings below those of other options.
  • Shell Type Traction Transformer: The windings of a shell-type transformer are encircled by the magnetic core. The magnetic core is positioned inside the windings, and the windings are encased in the core like a shell. Typically, the windings have a concentric or cylindrical structure. It gives windings more mechanical support and improved short-circuit strength. Because of the winding configuration, it is more easily cooled and adjustable for larger power ratings.

By Application

Based on application the global market can be categorized into Electric Locomotives, High Speed Trains, Electric Multiple Units (Emus), Trams and others.

  • Electric Railways: Rolling Stock Drive An essential part of electric locomotives are transformers. They are in charge of transforming third rail or overhead catenary high-voltage AC electricity into the appropriate voltage and frequency needed by the traction motors. This makes it possible for the locomotive to provide the power required for motion.
  • High-Speed Trains: Robust and potent traction systems are necessary for high-speed trains, which run at considerably faster speeds than conventional trains. In order to reduce the high-voltage electricity coming from the electrified infrastructure to the levels needed by the traction motors of the high-speed train, rolling stock traction transformers are essential. They enhance the high-speed train services' overall effectiveness, dependability, and performance.
  • Electric Multiple Units (EMUs): EMUs are made up of several vehicles, each having a separate traction system. Each vehicle has Rolling Stock Traction Transformers that convert the incoming high-voltage AC electricity to the right levels for the traction motors. In suburban and regional train services, EMUs are frequently utilized to provide effective and adaptable transportation.
  • Trams: Often referred to as streetcars or trolleys, trams are powered by either a track-based power source or overhead wires. The similar process is carried out by rolling stock traction transformers in trams, which transform incoming high-voltage AC power into the amounts needed for the tram's traction motors. For efficiency and environmental concerns, electrification of trams is a preferred option for urban transportation.

DRIVING FACTORS

Rail Electrification Initiatives and High-Speed Rail Development to Electrify the Market Growth

Initiatives to electrify trains have surged as a result of the worldwide movement toward environmentally friendly and sustainable modes of transportation.
