Description

Isolation Transformers Market Size:

Global Isolation Transformers Market is expected to grow at a 7.06% CAGR, achieving USD 2.950 billion by 2030 from USD 2.098 billion in 2025.

A transformer used to transfer electrical power from an alternating current source to a piece of equipment or device while isolating the powered item from the power source is known as an isolation transformer. This is typically done for safety concerns or to lessen transients and harmonics. The isolation transformations are used by many businesses to handle big voltage swings. The superior safety characteristics of these transformers are expected to boost their demand, thereby improving their overall market growth. The rising use of sensitive equipment such as computers and the need for microprocessor-based components has expanded across various industries, including medical equipment and electronics equipment is also anticipated to boost the demand for isolation transformers, thereby propelling the overall growth during the forecasted period.

 

Isolation Transformers Market Growth Drivers:

  • The global surge in energy demand is propelling the market growth.

Reliable power quality is necessary to operate sophisticated and delicate electronic equipment efficiently. Galvanic isolation, a safety feature that aids in preventing high-voltage electricity, is a function that is available for isolation transformers. With this crucial characteristic, isolation transformers are quickly replacing other options in the UPS and inverter industries. These isolation transformers are typically installed at the inverter's output end in UPS systems to improve the system's overall performance and the connected loads' quality of power supply. The rising inverters installation due to energy demand will boost the market growth. According to the International Energy Agency (IEA), India's energy demand is expected to climb by roughly 35% between 2019 and 2030, while the country's urban population will rise by an additional 270 million people during the following 20 years. According to projections from the U.S. Energy Information Administration (EIA), in 2021, the nation utilized 97 quadrillion BTUs of primary energy in total. This rising energy demand will accelerate the adoption of isolation transformers during the forecast period.

Isolation Transformers Market Segmentation Analysis:

  • Isolation transformers are increasingly finding application in the medical sector.

The isolation transformers are used in the medical industry as their application is to prevent incidental human contact with a live conductor, protecting users from electric shock and reducing electrical noise from damaging sensitive equipment. The CAT and MRI scanners are some of the most typical devices that use medical-grade isolation power transformers. The construction of new facilities in numerous nations worldwide helps MRI systems be adopted more frequently, boosting the market growth. For instance, in November 2021, the National Brain Research Centre (NBRC), Manesar, in Haryana, India, debuted a high-tech MRI facility. The National Brain Research Centre (NBRC) now has a Siemens MRI Scanner PRISMA 3T MRI. A rising cancer rate will increase the usage of MRI, which will also boost the market growth. According to Canadian Cancer Statistics, published in October 2021, it was anticipated that 229,200 Canadians would be diagnosed with cancer in the year 2021. In addition, it was noted that 46% of all cancer diagnoses in the nation are anticipated to be for lung, breast, colorectal, and prostate cancers in 2021. These factors thus increase the application of isolation transformers in the medical sector, boosting the overall market growth.

Isolation Transformers Market Geographical Outlook:

  • Asia Pacific accounted for a significant share of the global isolation transformers market. 

The need for isolation transformers is predicted to rise throughout the projection period due to the rising rate of industrialization and urbanization and increasing production of electric equipment, particularly in China, India, Japan, Taiwan, and South Korea. According to International Trade Administration, Taiwan's electric power equipment production has increased from 6,565,845 in 2019 to 7,436,175 in 2022. Additionally, the government regulations are designed to promote foreign direct investment, which is predicted to open new doors for manufacturers in several industries, including the energy sector, which will enhance demand for energy and increase the production of equipment that will require isolated transformers and hence will boost the market growth. In November 2021, according to the Ministry of Power, the "Integrated Power Development Scheme" (IPDS), which was announced on December 2014 to expand the power sub-transmission and distribution networks in metropolitan areas, received GoI Grants totaling Rs. 78 crores by November 2021 under IPDS which is around Rs. 30,904 crores worth of projects and have been approved, to the States and Discoms. The growing electronics equipment and the power and transmission sector in the region are expected to boost isolation transformer demand in the Asia Pacific, thereby propelling the overall market growth during the forecasted period.
