Knkong Electric's dry-type transformer technology has reached the world's advanced level
Over the past 20 years, with the development of the world economy, dry transformers have achieved rapid development around the world, especially in distribution transformers, dry transformers account for an increasing proportion. According to statistics, in developed countries such as Europe and the United States, It has accounted for 40-50% of the distribution transformer.
In China, dry-type transformers currently account for about 15%-20% of the average in large and medium cities, while in Beijing, Shanghai, Guangzhou, Shenzhen, and other cities, they account for about 50%, but due to the rural power distribution network in China, There are relatively few applications of dry-type transformers. Therefore, overall, dry-type transformers account for between 10-15% of transformer applications.
Foresight Industry Research Institute's 2013-2017 China Dry-type Transformer Industry Market Demand Forecast and Investment Strategic Planning Analysis Report shows that the dry-type transformer has four structures: epoxy resin casting, pouring with filler, wrapping, and dipping. At present, the dry-type distribution transformer with the largest capacity for short-circuit test in China is 3150kVA, 10/0.4kV;
