China Dry-type Transformer Industry Panorama Insight 2025: In-depth Analysis of Classification, Industry Chain and Production Trend

With the rapid development of China's economy, the demand for electricity is also increasing. Transformer as an important part of the power system, its market demand has climbed. Especially in terms of efficient and safe power transmission, dry-type transformers have gradually become the market favorite by virtue of their unique advantages. In this article, we will deeply analyze the classification, industry chain structure and future production trend of China dry-type transformer industry in 2025 to reveal the development trend of this industry for readers.

The basic concept and advantages of dry-type transformer

Dry-type transformers, i.e., transformers in which the iron core and coils are not immersed in insulating oil, are mainly cooled by air. Compared with oil-immersed transformers, dry-type transformers use resin or insulating paper as their insulating medium, providing higher safety and insulation levels. Its main advantages include:

High safety: dry-type transformers have virtually no risk of oil leakage, avoiding the danger of explosion.

Maintenance-free: unlike oil-immersed transformers, which require regular grease replacement, dry-type transformers require little additional maintenance during use.

Environmentally friendly: because they do not use grease, they reduce the possibility of contamination and can be used in a wider range of environments. However, dry-type transformers are relatively costly and are usually used indoors or in situations with high safety requirements, while oil-immersed transformers are mostly used outdoors.

Industry chain analysis

The industrial chain of dry-type transformer can be divided into two parts: upstream and downstream. The upstream mainly includes common steel, silicon steel sheet, non-ferrous metals (such as copper, aluminum) and epoxy resin used to encapsulate the transformer and other materials. The manufacture of dry-type transformers not only requires superior material performance, but also relies on a reasonable production process.

Epoxy resin, as a key material for dry-type transformers, accounts for 15-20% of the cost. According to statistics, China's production of epoxy resin reached 1.34 million tons in 2021, showing a steady growth trend.

The downstream application field is wide, involving petroleum and petrochemical, electric power construction, rail transportation and other industries. Especially with the development of renewable energy, the demand for dry-type transformers is becoming more and more prosperous, especially in the emerging fields of photovoltaic, wind power and other emerging areas with good application prospects.

Future production trends and industry analysis

The market demand for dry-type transformers is expected to continue to grow through 2025, mainly due to:

Continued national investment in power infrastructure construction, especially in the context of rapid urbanization.

Increased demand for safe power supply and environmental protection in various industries, driving up the demand for dry-type transformers.

The development of new energy industry has driven the application of dry-type transformers, especially in wind power and photovoltaic power generation access support.

In terms of the overall market, the production level of dry-type transformers continues to climb and is expected to reach a new peak in 2025. At the same time, with the advancement of technology, future dry-type transformers will have a higher level of intelligence, improve energy efficiency and reduce operating costs.

Conclusion

Dry-type transformers are gradually occupying a larger share of the market due to their advantages of safety, maintenance-free and environmental protection. In the future, with the increasing development of the power industry and the promotion of renewable energy applications, the demand for dry-type transformers will continue to increase, leading to the transformation and upgrading of the entire industry. Investment and research institutions should pay attention to the development of this field, layout in advance to grasp the upcoming market opportunities. For related enterprises, improving the production process and material use efficiency will be an important way to enhance competitiveness.
