Dry transformers refer to transformers whose iron cores and windings are not immersed in insulating oil, and they achieve cooling through air convection and other means. They have characteristics such as flame resistance, fire prevention, explosion-proof, and environmental protection, making them safe and reliable to use, easy to install and maintain. They can be placed deep into load centers and are widely used in high-rise buildings, subways, train stations, airports, hospitals, petrochemical enterprises, and underground mines.
As early as the mid-20th century, countries around the world began to use dry transformers, and China started to introduce dry transformers in the 1980s and 1990s. Now, China's transformer production has reached international standards, focusing not only on protecting its intellectual property rights but also continuously conducting product research and development.
With the rapid development of China's economy, there has been a widespread phenomenon of power shortages in the southeastern coastal areas. The long-standing issue of "heavy generation and light transmission" in China's power development has gradually been exposed, highlighting a weak link in the development of China's power industry—insufficient grid facilities. After 2006, grid construction surpassed power source construction, becoming the main investment focus in power construction.
The report "2013-2017 China Dry Transformer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" by the Forward Industry Research Institute shows that the proportion of grid investment has risen from 32.10% in 2005 to 49.47% in 2012. The investment structure has become more reasonable, improving the trend of excessive scale, rapid growth, and high proportion of power source investment in recent years. The power source and grid have begun to coordinate and develop scientifically. In 2012, the completed investment in China's grid engineering construction was 369.3 billion yuan, a year-on-year increase of 0.3%, with the growth rate decreasing by 6.49 percentage points compared to the same period last year.
With the acceleration of urban and rural grid construction, China's power generation and consumption are increasing day by day. Generally, for every additional 1 kW of power generation, an increase of 11 kVA in total transformer capacity is required; among which, distribution transformers account for about 1/3 to 1/2 of the total transformer capacity. It is estimated that dry distribution transformers account for about 1/5 to 1/4 of all distribution transformers. Overall, including the application of power distribution transformers, the proportion of dry transformers in China is between 10% and 15%.
Due to the pull of investment in grid construction, the market prosperity in the transmission and distribution field is rising, and the output of dry transformers will show a continuous upward trend. The report "2013-2017 China Dry Transformer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report" by the Forward Industry Research Institute shows that in 2012, under the influence of the decline in overall economic growth, China's dry transformer output was 18,607.19 million kVA, a year-on-year increase of 8.45%. In 2013, China's dry transformer output is expected to be around 19,723.62 million kVA, and by 2015, it will reach around 220 million kVA, with an expected output of about 245 million kVA by 2017.
