Dry Type Transformer Market Size

The global dry type transformer market size was valued at USD 17.25 billion in 2025 and is projected to grow from USD 18.21 billion in 2026 to USD 28.10 billion by 2034, registering a CAGR of 5.57% during the forecast period from 2026 to 2034. Asia Pacific dominated the dry type transformer market with a market share of 38.6% in 2025.

A dry type transformer is one that uses forced or natural air cooling in place of oil and is built using relatively modern technology. Dry type transformers only use high-temperature insulation systems that are safe for the environment, in contrast to liquid-fill transformers that need oil or liquid to cool. It has no moving parts, so it requires little maintenance while providing dependability and a long lifespan. These transformers can be easily installed in hospitals, schools, factories, chemical plants, and other structures where fire safety is a major concern because they are completely risk-free. Cast resin and vacuum-impregnated (VPI) dry type transformers are the two technology-based segments of the global market. In a vacuum pressure-impregnated (VPI) transformer, the live part is impregnated under pressure by an epoxy varnish in a vacuum chamber. In a cast resin transformer, the live part, consisting of the core and windings, is encapsulated inside a resin, which is in liquid form when put in the molds along with a hardening agent. Even after impregnation, VPI allows access to the live part while still providing excellent fire protection ratings.

Dry Type Transformer Market Segmentation Analysis

By Type

Based on type, the global market is bifurcated into dry type converter transformers and dry type converter rectifier transformers. The dry type converter transformer segment is the highest contributor to the market and is expected to grow at a CAGR of 5.8% during the forecast period. Transformer converters are used to change power from A.C. to D.C. at one end and from D.C. to A.C. at the other. As semiconductor converters in the traction substation for the city's electrified public transportation (tram, trolley bus, and subway), converter transformers are primarily used in excitation systems for turbo and hydro-generators, electric drives of drilling equipment, and D.C. & A.C. electric drives.

The dry-type converter rectifier transformer segment is expected to witness a higher CAGR of 6.2%. Transformers known as rectifier transformers (rectiformers) contain diodes or thyristors in the same tank. They are employed in industrial processes that need a sizable supply of direct current (dc). D.C. traction, electrolysis, smelting operations, and sizable variable-speed drive trains are examples of typical processes. In a D.C. electric substation for railway applications, rectifier transformers with ratings of 3150 kVA and 22 kV are used. They have a wide range of uses, including powering devices like radios, T.V.s, computers, and other electronics that require a steady D.C. supply. Dry type rectifier transformers are therefore utilized in both residential and commercial building spaces.

By Techology

Based on technology, the global market is bifurcated into cast resin and vacuum pressure impregnated. The cast resin segment is the highest contributor to the market and is expected to grow at a CAGR of 5.8% during the forecast period. The magnetic circuit and windings are cast with an epoxy resin mixture instead of being submerged in an insulating liquid in a typical cast resin dry type transformer. Copper conductor windings for high-voltage (H.V.) and low-voltage (LV) applications are completely impregnated with epoxy resin and cast under a vacuum. The winding material is shielded from moisture by this encapsulation. CRTs are suitable for indoor applications because their winding is protected from fire hazards by non-flammable epoxy resin. CRTs are also perfect for use in areas that are prone to moisture because of the insulation.

The vacuum pressure-impregnated segment is expected to witness a higher CAGR of 6.4%. The transformer windings are impregnated with polyester or epoxy resin under vacuum pressure in order to replace air bubbles, dust, and other small particles with dielectric resin. This process eliminates any potential causes of local weakening in the insulation system. Transformers are polymerized in an oven following the initial impregnation using carefully timed thermal cycles. The conductor material, insulation, and resin are all solidified together during this process, improving both the mechanical and electrical properties. As a winding insulator, fiberglass, mica, or aramid paper is used to achieve self-extinguishing properties.

By Phase

Based on phase, the global market is bifurcated into single-phase and three-phase. The single-phase segment is the highest contributor to the market and is expected to grow at a CAGR of 5.9% during the forecast period. Transformers of the single-phase dry type is suitable for applications requiring less than 1,000 watts of power. They are utilized as electronic devices and home appliances in low-voltage commercial applications. In addition to serving as a step-down voltage transformer, single-phase dry type transformers can also provide enough power to tune electric motors up to 5 horsepower (hp). A single-phase dry type transformer installed in residential and commercial spaces reduces the high voltage that is received from the power grid. To balance the total phase impedance in applications of contemporary steel processes, three single-phase furnace dry-type transformers rather than a single three-phase transformer are used in steel plants.

The three-phase segment is expected to witness a higher CAGR of 6.4%. The voltage can be changed from one side of a three-phase dry type transformer to the other. But compared to a single-phase dry type transformer, it can distribute three times as much power. Data centers, mobile towers, and power grids are some of the main applications for three-phase dry type transformers. Induction motors need three-phase power to run in an industrial setting. Compared to single-phase transformers, a three-phase dry type transformer can run at higher power loads. Because three-phase transformers can carry loads greater than 1000 watts, which are required to operate some industrial machinery, auxiliaries, and motors, they are used in more commercial applications than single-phase transformers.

By Voltage

Based on voltage, the global market is bifurcated into low-voltage and medium-voltage. The low-voltage segment is the highest contributor to the market and is expected to grow at a CAGR of 6.1% during the forecast period. The voltage is typically stepped down using low-voltage dry type transformers (LVDT), which are bought from utility companies. Buildings employ LVDTs to reduce the incoming voltage so that appliances, lighting, and other consumer electronics can be powered. It is rated for voltage at less than 600 volts. They are typically produced using VPI technology, and they have a wide range of regular and unique applications in commercial buildings, ships, deep mines, and other industrial settings.

The medium-voltage segment is expected to witness a higher CAGR of 5.6%. Commercial and industrial businesses, governmental organizations, and other large facility operators are the main owners of medium-voltage dry-type distribution transformers. The transformer receives an incoming voltage in the range of 5 kV to 35 kV. For use in commercial, institutional, or industrial applications, they are primarily used to step down medium-voltage power to a lower operating voltage. Transformers with a medium voltage can also be used to step up voltage, though. The expansion of end users like the commercial and residential sectors affects the demand for medium-voltage dry type transformers. These transformers are replacing conventional oil-filled transformers in places like hospitals, schools, factories, chemical plants, and buildings where fire safety is a major concern because they are completely risk-free.

By End Use

Based on end use, the global market is bifurcated into industrial, commercial, and others. The industrial segment is the highest contributor to the market and is expected to grow at a CAGR of 5.8% during the forecast period. The industrials segment consists of the use of dry type transformers as step-up or step-down voltages in industrial power distribution systems. The majority of industrial facilities have environments that make it unsafe for wet transformers to operate safely, which is why the demand for dry type transformers is rising. The adoption of dry-type transformers in industrial settings is influenced by features like excellent overload tolerance, eco-friendliness, non-combustibility, and excellent impulse voltage strength. Additionally, dry type transformers are built to be humidity resistant, and the lack of a cooling liquid completely eliminates the possibility of an oil spill.

The commercial segment is expected to witness a higher CAGR of 6.2%. Commercial structures, including airports, water treatment plants, hospitals, hotels, underground stores, stadiums, educational facilities, and shopping malls, are among the commercial spaces that use dry type transformers. Private and public electricity distribution companies are other industrial end-user of dry type distribution transformers. In order to lower the building distribution voltage to a level that can be used by particular equipment, dry type transformers are also installed indoors. Commercial buildings typically have step-down transformers to reduce the voltage from a higher utility distribution voltage (7 to 25 kV) to a lower utilization voltage.
