Analysis of market demand for dry-type transformer industry in China

Author:


In the past 20 years, with the development of the world economy, dry transformer has made rapid development in the world, especially in distribution transformers, the proportion of dry transformer is getting larger and larger. According to statistics, in developed countries such as Europe and the United States, it has accounted for 40-50% of distribution transformer. In 2012, China's dry-type transformer output was 186.0719 million kVA, which is one of the countries with the largest production and sales of dry-type transformers in the world. Dry-type transformers are now widely used in power stations, factories, hospitals and almost all electrical. In China, dry-type transformers currently account for about 15%-20% on average in large and medium-sized cities, while in Beijing, Shanghai,

In the past 20 years, with the development of the world economy, dry change has made rapid development in the world, especially in the distribution transformer, the proportion of dry change is growing, according to statistics, in Europe and the United States and other developed countries, it has accounted for 40-50% of the distribution.
 
In 2012, the output of dry-type transformer in China was 186.0719 million kVA, which is one of the countries with the largest production and sales of dry-type transformer in the world. Dry-type transformers are now widely used in power stations, factories, hospitals and almost all electrical. In China, the current dry-type transformer in large and medium-sized cities in an average of about 15%-20%, and in Beijing, Shanghai, Guangzhou, Shenzhen and other cities, about 50%, but due to the application of dry-type transformers in China's rural distribution network is relatively small, therefore, on the whole, dry-type transformers accounted for between 10-15% of transformer applications.
 
Compared with developed countries, the market share of dry transformer in China is still low, but with its excellent application conditions and performance, the proportion of dry-type transformer in the total output of transformers will rise to a certain extent. It is estimated that by 2020, my country's dry change market share will reach about 50%, which is equivalent to the current proportion of developed countries. Therefore, my country's dry change market still has a long way to go.
 
"2013-2017 China dry-type transformer industry market demand forecast and investment strategic planning analysis report" shows that dry change has four structures: epoxy resin pouring, filling pouring, wrapping, impregnation. At present, Europe and the United States widely used open ventilation H-class dry-type transformer, is on the basis of the immersion of the characteristics of the winding structure and the use of Nomex paper after the development of the new H-class dry change, due to the high price, in China has not been promoted.
 
At present, the dry-type distribution transformer with the largest short-circuit test capacity in China is 2500kVA and 10/0.4kV. The dry-type power transformer with the largest short-circuit test capacity is 16000kVA and 35/10kV. With the popularization and application of SC(B)9 series with low noise (distribution transformer noise below 2500kVA has been controlled within 50dB) and energy saving (no-load loss reduced by 25%), the performance index and manufacturing technology of dry-type transformer in China have reached the world advanced level.
