The global dry type transformer market size was valued at USD  6.23 billion in 2023. The market is projected to grow from USD 6.51 billion in 2024 to USD 10.47 billion by 2032, exhibiting a CAGR of 6.12% during the forecasted period.

A dry-type transformer is an electrical transformer that uses solid insulation materials, such as epoxy resin and fiberglass to insulate the windings and core, thereby eliminating the need for liquid dielectric materials, such as oil. These transformers are designed to provide electrical isolation and voltage transformation in various applications. They are called "dry-type" as they do not rely on a liquid coolant or insulating oil for their operation. Instead, they dissipate heat generated during operation through natural convection or forced air circulation. Dry-type transformers are known for their environmental friendliness, fire resistance, and suitability for a wide range of indoor and outdoor installations. There are two types of transformers which come in different phases, such as single phase and three phase which have various uses and applications. These factors are expected to boost the market growth in the coming years.

The COVID-19 pandemic disrupted the global supply chains, causing delays in the production and delivery of electrical equipment, including dry type transformers. Manufacturers faced challenges in sourcing materials and components, which led to production slowdowns and increased costs. Many manufacturers relied on a complex network of suppliers and sub-suppliers to source materials and components necessary for building these transformers. Many factories across the globe temporarily shut down or reduced their production capacity to comply with lockdowns, social distancing measures, and workforce shortages. This led to delays in the supply of critical components. With disruptions in the supply of important materials and components, manufacturers of these transformers faced challenges in maintaining their production schedules. This resulted in production delays and potential backlogs.

Dry Type Transformer Market Trends

Increasing Adoption of Renewable Energy to Propel Market Growth

The increasing adoption of renewable energy sources has had a positive impact on the market for dry type transformers. Renewable energy sources, such as wind and solar power often require transformers to step up voltage levels for efficient electricity distribution and transmission. Dry type transformers are commonly used in these applications due to their environmental friendliness and safety features, making them a preferred choice in renewable energy projects.

For instance, In October 2022 Hitachi Energy India Limited (Hitachi Energy) has received an order from NTPC Renewable Energy Limited (NTPC REL) to supply power transformers for its upcoming 4.75 GW renewable energy park in Gujarat. This is part of India's largest solar park, spread over 72,600 hectares in Kutch. This will increase the adoption of renewable energy.

Latest Innovations in Transformers and Its Components to Propel Market Growth

Manufacturers are focusing on enhancing the efficiency of dry type transformers. This involves the use of advanced materials, better core designs, and improved winding techniques to reduce energy losses and make them more attractive to energy-conscious customers. New features, such as use of fire-resistant materials are making transformers safer and more reliable, creating more demand for them and accelerating the market growth.

For instance, In June 2023 Hitachi showcased its latest innovations in transformer insulation and components, offered interactive sessions with experts, and hosted a product launch of the latest addition to its implementation portfolio.

Dry Type Transformer Market Growth Factors

Increasing Demand for Electricity to Drive the Dry Type Transformer Market Growth

As the global population continues to increase, especially in urban areas, the demand for electricity rises. Urbanization leads to the development of residential, commercial, and industrial infrastructure, all of which require reliable electricity supply. Dry type transformers play an important role in effectively distributing electricity in these urban environments. Industrialization is a major driver of electricity demand. Industries, such as manufacturing, mining, and construction, need substantial amounts of electricity to power their operations. As countries undergo economic development and industrialize further, the demand for electricity increases, thereby driving the demand for transformers, comprising dry type transformers, to ensure efficient power distribution.

Thus, the increasing demand for electricity, driven by factors, such as population growth, urbanization, industrialization, technological advancements, renewable energy integration, and infrastructure renewal, is a key driver for the growth of the dry type transformer market. As per the latest update in December 2023 by the U.S. Energy Information Administration, the U.S. electricity consumption in 2022 was about 3.2% higher than in 2021. In 2022, retail electricity sales to the residential sector were about 2.6% higher than in 2021, and retail electricity sales to businesses were about 4.7% higher than in 2021. Thus, the increasing demand for electricity drives the dry type transformer market growth.

Upgrade of Aging Power Distribution and Transmission Infrastructure to Accelerate Market Development

Modernization of the ageing power distribution and transmission systems is expected to drive the growth of the market. This trend is increasing due to the rising domestic electricity demand and rapid industrialization, which has led to the expansion of distribution and transmission networks. The increasing demand for modernized and intelligent power distribution infrastructure will likely create numerous market opportunities. In addition, using the vacuum pressure impregnation technology increases the penetration of transformers in moisture-prone areas, which is expected to increase the product demand.

For example, Canada and the U.S. have quite an old infrastructure of transmission lines that are over 50 years old. To cater to the rising electricity demand, Canada needs to upgrade its existing infrastructure while substantially increasing the capacity of the grid. By 2050, the total investment is expected to reach more than USD 1.1 trillion.


High Initial Costs to Hinder Market Growth

One of the primary challenges associated with these transformers is their higher upfront cost as compared to that of oil-filled transformers. It requires specialized insulation materials to ensure proper electrical insulation and thermal performance. These materials are often more expensive than the oil and paper insulation used in oil-filled transformers. The design and construction of these transformers can be more complex than those of their oil-filled counterparts. These transformers may include features, such as epoxy resin casting or Vacuum Pressure Impregnation (VPI), which require precision engineering and specialized manufacturing processes.

Dry Type Transformer Market Segmentation Analysis

By Rating Analysis

Development of Advanced Rotary Bit Technologies Drove the Use of 5 MVA to 30 MVA Dry Type Transformers

Based on rating, the market is segmented into less than 5 MVA, 5 MVA to 30 MVA, and above 30 MVA.

The 5 MVA to 30 MVA segment held a larger market share in 2023. The development of advanced rotary bit technologies propelled their adoption in the mining industry. Manufacturers are introducing innovations, such as improved cutting structures, enhanced materials, and better designs to make rotary bits more effective and efficient for mining applications. Rotary bits can offer higher drilling speeds and better penetration rates in certain geological formations. Mining companies may opt for these bits to increase productivity and reduce overall drilling costs.

By Installation Analysis

Due to the Initiation of Advanced Product Design Indoor Transformer Will enhance the market share of this segment

Based on the Installation the market is segmented into Indoor and Outdoor. The Indoor type segment is leading the global market. Indoor types are specifically designed to be installed indoors, typically in enclosed spaces, such as utility rooms, substations, or industrial buildings. They are constructed to be compact and often have features, such as noise reduction to minimize the impact of background noise on the indoor environment. Indoor transformers do not require additional protective enclosures or housing as they are designed for a controlled and sheltered environment.

On the other hand, the outdoor transformers are designed for installations in open-air environments where they are exposed to weather conditions, such as rain, snow, and sunlight.
