Gas-Insulated Transformer Market Size, Share, and Industry Analysis, By Installation (Indoor and Outdoor), By Voltage (Low (Up To 72.5 kV), Medium (72.5 kV - 220 kV), and High (Above 220 kV)), By End-User (Industrial, Commercial, and Utility), and Regional Forecast, 2025-2032

The Gas-Insulated Transformer (GIT) is a device used in hydropower and underground electrical distribution network systems. It offers the best solution for overcoming the sharp increase in electric power demand in large and metro cities. SF6 gas is employed as an insulating and cooling agent in GITs, which is why it is also called an SF6 insulated transformer. SF6 insulated transformers or GITs are characterized by non-flammability insulation effects and safety and are designed to reduce fire hazards and less risk to the environment. Gas-insulated transformers are preferable to conventional transformers in many different ways, such as they don't require regular oil checks and replacement and are non-combustible and non-explosive. When non-flammable, non-polluting transformers are required, Gas-Insulated Transformers (GIS) are used. Moreover, with increasing demand, key players are investing in R&D to innovate new products.

• In December 2021, Arteche and Hitachi Energy collaborated on a joint venture in Arteche Gas Insulated Transformers (AGIT). Under this partnership, both companies focus on and invest in R&D for the sustainable gas-insulated transformer market. In this collaboration, Arteche holds a 51% majority stake, while Hitachi Energy holds 49%, strengthening its position in the field of both.

The halt in the supply chain due to the COVID-19 pandemic caused a delay in many projects in new electricity generation capacity. Meanwhile, demand and prices were reduced, and investments in this sector were also impacted as consumer spending on oil and gas fell drastically. According to IEA, almost all the investment activity was disrupted as a result of restrictions on the movement of people, goods, and equipment. Overall, the impact of the COVID-19 pandemic on the gas-insulated transformer market was negative.

SEGMENTATION

 ANALYSIS BY VOLTAGE

Based on voltage, the market is segmented into Low (Up To 72.5 kV), Medium (72.5 kV - 220 kV), and High (Above 220 kV). Gas-insulated transformers with low voltage can reach upto 72.5 kV power voltage. Owing to harsh climatic conditions and limited space availability, North America and Europe's manufacturing, automotive, and commercial sectors use gas-insulated transformers for various applications. High T&D efficiency, lower emissions, high fire resistance, and increased safety monitoring configuration are benefits of these units. These factors drive the demand for gas-insulated transformers and are also expected to increase demand over the forecast period.

220 kV high-voltage cable is also sent out using a cable box, SF6 gas, and an SF6 gas sleeve. Some of the benefits of high-voltage gas-insulated transformers include increased fire resistance, explosion resistance, safety monitoring, and protection configuration, which is expected to create growth opportunities for these products over the forecast period.

ANALYSIS BY INSTALLATION

Based on installation, the market is segmented into indoor and outdoor. Indoor installation is the fastest-growing segment, and this is attributed to its small size, low electromagnetic radiation emission, and reduced noise level. These transformers are being frequently used for underground and indoor installations in large and metro cities, which is expected to impact the market positively.

Outdoor transformers are used for converting line voltage input to low voltage output, specifically for safe outdoor use. Outdoor gas-insulated transformers are used to transmit and distribute electricity over a long distance.

ANALYSIS BY END-USER

Based on end-user, the market is segmented into industrial, commercial, and utility.

The industrial sector dominates the global market, followed by the commercial sector and then the utility sector. In the industrial sector, low maintenance and severe space restrictions are the key factors contributing to the excess use of gas-insulated transformers. As governments and key players are focusing on increasing manufacturing capacities to support economic growth, the use of this transformer has become essential. Thus, this increases the demand in the market.

The commercial segment is projected to increase over the coming year due to various development initiatives, which will eventually increase the demand for electricity. Due to the small size of gas-insulated transformers, it offers additional benefits to shopping malls, theaters, and other large building complexes, which are in densely populated cities with limited land.

REGIONAL ANALYSIS

The gas-insulated transformer market has been studied across North America, Europe, Asia Pacific, Latin America, and the Middle East & Africa. Asia Pacific dominates the gas-insulated transformer market.

Increasing population, urbanization, and industrialization in this region are leading to an increase in demand for electricity. Owing to these requirements, transmission and distribution (T&D) infrastructure investments have also increased significantly. Gas-insulated transformers are widely used in residential and commercial sectors for efficient power supply and to prevent fire incidents. China and India are major countries that are propelling the market for gas-insulated transformers in the Asia Pacific region.

North America is a major producer and consumer of electricity for various applications, and the rapidly increasing market of electricity in the U.S. and Canada creates profitable opportunities for advanced safety technologies such as gas-insulated transformers.

In Europe, investments in renewable technologies, such as solar and wind power, for energy diversification are the latest trend in the region. Moreover, the government's policies regarding the advancement of renewable energy are adding to renewable energy share in the total energy production in the region. The market is anticipated to grow owing to several policies, eventually promoting the application of gas-insulated transformers to increase the renewable energy sector. Moreover, growth is expected in Latin America and the Middle East & Africa regions due to infrastructure developments and various intergovernmental initiatives and collaborations to help advancements in the energy sector in these regions.
