Market Overview

The global gas-insulated transformer market size was valued at USD 2,421.54 million in 2022. It is expected to reach USD 3,756.6 million by 2031, growing at a CAGR of 5% during the forecast period (2023–2031).

Gas-insulated transformers are highly sophisticated devices typically used in hydropower and underground electrical distribution networks. Densely inhabited urban areas, vital infrastructure substations, and offshore substations are typical locations for this. Gas-insulated transformers are superior to dangerous conventional transformers in several ways, including not requiring regular oil checks or replacement, never leaking oil, and being non-combustible and non-explosive. Due to these benefits, there has been a rise in the demand for gas-insulated transformers. When non-flammable, non-polluting transformers are required, gas-insulated transformers (GIS) are used. For instance, they are used where a conventional transformer's oil leak would be hazardous to the environment, such as in buildings, areas close to lakes and rivers, and densely populated areas. Gas-insulated transformers are made to cause less environmental damage and have fewer fire risks.


Market Dynamics

Global Gas-Insulated Transformer Market Drivers:

Investments in Transmission and Distribution Infrastructure

In recent years, power consumption has significantly increased in developing economies. Governments and power companies established reforms to reduce power losses in the transmission and distribution infrastructure and use environmentally friendly and efficient equipment to build T&D networks and related infrastructure. Many nations use gas-insulated transformers (GITs), especially for gas-insulated substations. GITs and gas-insulated switchgear (GIS) can be connected directly, eliminating the need for a separate transformer room. A gas-insulated substation (GIS), a typical configuration for inner-city applications and structures, is created by this arrangement. According to the European Network of Transmission System Operators, until 2030, there will be a need for annual transmission spending of about USD 10 billion. As variable renewables and electrification increased significantly in the region, investments in Europe stayed stable at close to USD 50 billion, with increases in spending on upgrading and refurbishing the existing grid.

Global Gas-Insulated Transformer Market Restraints:

Concerns and Strict Environmental Regulations

Sulfur hexafluoride (SF6) gas is frequently used in gas-insulated transformers as insulation. The dielectric property of SF6 gas makes it suitable for insulated transformers as opposed to conventionally hazardous oil, which runs the risk of fire, explosions, and contamination leaks. SF6 gas is chemically stable, non-flammable, and highly electronegative. On the other hand, SF6 is a strong greenhouse gas with a potential for global warming that is roughly 23,500 times greater than that of CO2. The Intergovernmental Panel regards SF6 on Climate Change as one of the most potent greenhouse gases (IPCC). As a result, manufacturers and consumers must take all necessary precautions to limit the design and handling of leaks.

Additionally, the Environmental Protection Agency filed charges against Electricity Supply Board (ESB), a state-owned electricity provider in Ireland, in September 2020 due to SF6 leaks. Six charges were brought against the company due to gas leaks at its power plant in Moneypoint, County Clare. According to the Environmental Protection Agency's (EPA) final report on Moneypoint, ESB released 55,000 tons of CO2 equivalent into the atmosphere during the preceding six years. During the forecast period, similar scenarios are likely to restrain the growth of gas-insulated transformers.

Global Gas-Insulated Transformer Market Opportunities: 

Growing Interest in Offshore Wind Power in Emerging Economies

Many significant economies use gas-insulated transformers (GITs) to reduce the need for a large transformer room and safety concerns. In offshore substations for wind farms, the GITs can be used as an alternative to conventional transformers to solve the problem of limited space. Vietnam is home to more than 1.5 GW of offshore wind projects, according to the Global Wind Energy Council (GWEC). Due to the government's ambitious plans, the offshore wind market in the nation will likely experience significant developments in the coming years. As a result, significant changes were opened to using gas-insulated transformers (GITs) in offshore wind substations. The government is also considering centralizing planning for offshore wind projects to ensure effective, fair, and transparent auctions and support the development of the necessary electricity network and industry-specific skills. The government's long-term goal, the upcoming offshore wind projects, and the growing interest in offshore wind power in emerging nations are all expected to create significant opportunities for gas-insulated transformers (GITs) soon.

Low voltage gas insulated transformer components include SF6 gas, an SF6 gas sleeve, a transformer on-load voltage regulation switch, a pressure monitoring device, a gas density gauge, a gas temperature gauge, a sudden pressure relay, a plate radiator, an airflow indicator, a winding temperature gauge, a gas circulation pump, a cooling system intelligent control box, and a blowing device. The transformer body has a coil, iron core, lead, pressure monitor, gas density gauge, sudden pressure relay, winding temperature gauge, and gas temperature gauge for secondary protection. The transformer uses SF6 as a cooling medium and internal insulator. Due to harsh climatic conditions and space limitations, North America and Europe's manufacturing, automotive, and commercial sectors will use gas-insulated transformers. High T&D efficiency, lower emissions than oil-based transformers, high fire resistance, and increased safety monitoring and protection configuration are benefits of these units. These factors are expected to increase demand for low-voltage gas-insulated transformers over the forecast period.

A box, a transformer body, a cable box, SF6 gas, an SF6 gas sleeve, a transformer on-load voltage regulation switch, a pressure monitoring device, a gas density gauge, a gas temperature gauge, and a sudden pressure relay are all parts of a high voltage gas insulated transformer (above 220 kV). A 220 kV high-voltage cable is also sent out using a cable box, SF6 gas, and an SF6 gas sleeve. The airflow indicator, plate radiator, blower, intelligent control box for the cooling system, and gas circulation pump cool the transformer. The SF6 gas is a cooling medium and an internal insulator for the transformer. Some significant benefits of high-voltage gas-insulated transformers include explosion resistance, increased fire resistance, safety monitoring, and protection configuration, which will likely increase demand for these products in the foreseeable future.

Based on the installation, the global gas-insulated transformer market is bifurcated indoors and outdoors.

The installation of gas-insulated transformers is intended for both indoor and outdoor applications. Due to their small size, reduced noise level, and low electromagnetic radiation emission, gas-insulated transformers are frequently used for underground or indoor installations in urban areas. To save space, ensure safety, and provide a steady supply of electricity, indoor installation of gas-insulated transformers is typically carried out in underground spaces beneath public parks and commercial buildings.

Outdoor transformers are made for safe outdoor use and convert line voltage input to the low voltage output. To transmit and distribute electricity over a great distance, outdoor installations of gas-insulated transformers are typically carried out in enclosures. Gas-insulated transformer enclosures are used for outdoor applications to shield the transformer from the elements, including any potential electrical equipment contamination. Additionally, some oil and gas production facilities are situated in remote locations, which makes it challenging to meet their energy needs. This power demand may be met by outdoor installation, propelling the segment's growth over the forecast period.

Based on the end-user, the global gas-insulated transformer market is bifurcated into industrial, commercial, and utility.

Gas-Insulated Transformers are used by industries with severe space restrictions and low maintenance needs. Aerospace, agribusiness, auto manufacturing, biopharmaceuticals, consumer goods, energy, environmental technology, machinery, and equipment are a few examples of different industries. Several nations worldwide are concentrating on growing their domestic manufacturing industries to support economic growth—one of the industries in India that is expanding the fastest in manufacturing. The Indian government started the "Make in India" program to promote the Indian economy internationally and establish the nation as a manufacturing hub. 

The commercial segment of the gas-insulated transformer market is expected to proliferate in the coming years as commercial end-users demand more electricity worldwide. Commercial electricity consumption peaks during business hours and off-peak periods have low baseloads. Gas-insulated transformers offer additional benefits due to their smaller size because most retail establishments, including shopping malls, multiplexes, and other large building complexes, are in densely populated areas with limited land. These transformers are 10% the size of standard air-insulated transformers and are housed in the terrace or basements of commercial buildings. Gas-insulated transformers are leak-proof and do not use oil, so an oil leak or spill during maintenance would not pollute the water supply. The commercial segment is expected to grow due to the environmental benefits of gas-insulated transformers in urban areas.
