An increase in power generation and grid development projects is what drives the total quantity of power transformers. Power transformer demand is driven by the modernization, development, and improvement of power grids, which also support the industry's overall growth. Some of the nations and areas leading the way in the implementation of smart grids are Japan, which in 2022 announced a USD 155 billion funding package to encourage investments in smart power networks.

The growing penetration of electric cars (EVs) offers power transformers the chance to assist in the creation of EV charging infrastructure. Transformers are essential for providing charging stations with an effective and dependable power supply. Power transformers are a necessary part of the infrastructure used to charge electric cars. They assist in reducing grid electricity from high voltages to lower voltages required for different EV charging capacities. Electric car charging is now safe and effective thanks to this development. Programs like the FAME India project, tax breaks, and production-linked incentives are designed to give the electric vehicle (EV) sector a boost.

Growth Drivers

  • Demand for Eco-friendly Transformers - In accordance with environmental concerns, eco-friendly transformers employ non-toxic and biodegradable insulating lubricants, which lessens their ecological imprint. In this regard, Enel Spa unveiled a brand-new electric transformer in July 2022 for use in solar parks. This transformer uses biodegradable fluids, emits less CO2, and requires less resources to build. In addition to requiring over 14 less tons of different materials to construct the transformers, this will save more than 45 metric tons of CO2 equivalent emissions. It was first used in Spain and was being launched globally.

  • Penetration of Phase Shifting Transformer - The power flow on the transmission grid is controlled by these transformers. They are designed to protect power lines and equipment with higher voltage from heat overloads while controlling the flow of electricity across both networks. PSTs can improve the real power handling of transmission lines, allowing for flexibility in the actual energy transfer, and have little impact on VAR. In general, PSTs increase the stability of transmission systems, decrease network losses, and improve their efficiency.

Challenges

  • Fluctuating Raw Material Prices - Copper, steel, and aluminum are the primary materials used to produce electricity transformers. Due to the increased overall prices for these raw materials, sales of power transformers will be reduced in middle and lower-income countries. During the production process, copper transformer windings allow for an easy weld. However, high material costs can be incurred due to excessive copper consumption.

  • Environmental Concerns associated are anticipated to hinder the power transformer market growth in the forecast period.

  • Significant capital investment need is another significant factor posing limitations on the power transformer market growth in the forecast period.

Power Transformer Market Segmentation:

Phase Segment Analysis

In terms of phase, the three-phase segment share in power transformer market is anticipated to surpass 61% by the end of 2035. Three-phase transformers have six windings, three for the primary and three for the secondary, connected in either a delta or a triangle configuration. These circuits can be regarded as part of a single-phase converter. Delta and star are the two most common forms of three-phase connections. A delta connection, also known as a mesh connection, consists of three windings connected at the end, forming a closed loop without a neutral point.

End User Segment Analysis

Based on end user, the industrial segment in power transformer market is anticipated to record the highest revenue share of 44% during the forecast period. These transformers are mainly used in industrial settings, such as manufacturing plants, refineries, mining operations, and other heavy-duty applications. To be able to withstand the intense operating conditions, heavy construction and insulation are commonly used in industry transformers. Industrial supply voltage in Canada stands at 600 VAC similar to that of the US at 480 VAC on the other hand Europe stands at 400 volts in common industrial voltage. The majority of factories are typically supplied with 480V three-phase power, but stepping down the transformers reduces the voltage to 240 V, 208 or 120 for small devices and appliances.
