China's dry-type transformer industry is gradually infiltrating into various fields, especially in the electronic and electrical industry, and the application scale has expanded. According to the market situation of dry-type transformers in China, about 70% are domestic brands, but the market share is less than 30%, and most of the market is still occupied by European brands. Especially in the field of small capacity, the technology content is not high, domestic enterprises have set foot in one after another, the productivity is saturated, and the market competition is fierce. In the field of high capacity, due to the lack of technical capacity and the backwardness of the market management concept, Chinese enterprises failed to occupy the mainstream.
At present, dry-type transformers account for about 10%~15% on average in ordinary cities, and about 50% in Beijing, Shanghai, Guangzhou, Shenzhen and other cities. However, due to relatively few applications of dry-type transformers in rural distribution networks in China, the overall dry-type transformers account for 15%~20% of transformer applications. In 2020, the sales revenue of China's dry-type transformer industry will be about 40.1 billion yuan. According to the analysis of Zhongyan Industrial Research Institute, the Special Feasibility Study and Investment Value Consultation Report of 2022 Dry Type Transformer Project
Dry type transformers are mainly used in traditional power generation fields such as thermal power and hydropower, and new energy power generation fields such as wind power, photovoltaic power generation and nuclear power, among which wind power is the most widely used and fastest developing new energy power generation technology in the world. In recent years, the demand of downstream industries related to dry-type transformer industry in China has continued to grow, showing a steady growth trend. Data shows that in 2019, the output of dry-type transformers in China will be about 273 million kilovolt amperes.
From 2013 to 2019, the number of new dry-type transformer enterprises in China increased year by year, reaching the highest point in 2019, with 982 dry-type transformer enterprises in that year and 846 in 2020. From January to June 2021, there will be 249 new enterprises in the office transformer industry in China.
From the perspective of output, the output of dry-type transformers in China has expanded with the expansion of the production capacity of the transformer industry in China. The output of dry-type transformers in China fluctuated from 2013 to 2018. In 2019, the output of dry-type transformers in China increased slightly, reaching 273 million kva. According to interviews with insiders and authoritative experts, the output of dry-type transformers in China will be about 251.5 million volt amperes in 2020.
China is the fourth fastest growing sales market and has become the fifth largest international sales market. Especially in the past year, the capital construction of projects such as power transmission from the west to the east, mutual supply between the north and the south, and inter regional interconnection network has been accelerated, which has promoted the rapid development trend of China's power transmission and transformation machinery and equipment manufacturing industry.
Judging from the current market trend of dry-type transformer sales, the dry-type transformer processing and manufacturing industry will also usher in a steady development trend in the next two years. However, in the sales market of dry-type transformers in China, the supply of low-end products exceeds the demand, while the gap between supply and demand of high-grade dry-type transformers is large.
Dry type transformers tend to be energy efficient
Significant achievements have been made in China's economic construction, but in the face of the severe situation of tight resource constraints, serious environmental pollution and ecosystem degradation, the report of the 18th National Congress of the Communist Party of China pointed out that we should adhere to the basic national policy of resource conservation and environmental protection, and form a spatial pattern, industrial structure, production mode and lifestyle of resource conservation and environmental protection. The report of the 19th National Congress of the Communist Party of China pointed out that we should promote the revolution in energy production and consumption and build a clean, low-carbon, safe and efficient energy system. The proposal of Transformer Energy Efficiency Improvement Plan (2021-2023): accelerate the promotion of energy-saving transformers. By 2023, the number of energy-saving transformers in the network will increase by 10%, and the proportion of energy-saving transformers in that year will reach more than 75%.
Therefore, the development, production and application of new energy-saving dry-type transformer products for wind, nuclear, solar, gas power and other new energy power generation industries and railway transportation, infrastructure, and various industrial enterprises is of great significance for improving energy shortage and strengthening environmental protection. In addition, the use of new materials and technologies in energy-saving dry-type transformer products can improve product performance and reduce appropriate energy consumption, thereby improving product operation quality and reducing operating costs.
