Transformer products, including power transformer, special transformer, mutual inductor, reactor and voltage regulator, are one of the main equipment in power transmission, transformation and distribution equipment.
Since the founding of the people's Republic of China, China's transformer manufacturing industry has developed from scratch, and the transformer manufacturing industry has developed by leaps and bounds. There are nearly 1000 enterprises with a certain scale, which can manufacture various products such as transformers, mutual inductors, reactors, voltage regulators and their supporting components. It is a profitable manufacturing industry with an annual output of about 140 million KVA and an output value of nearly 8 billion yuan. According to the statistics in 1998, in the total output of 133.83 million KVA, there is one enterprise with an annual output of 20 million kV, two enterprises with an annual output of 10-20 million KVA, 11 enterprises with an annual output of 2-6 million KVA, 14 enterprises with an annual output of 1-2 million KVA, and 22 enterprises with a total output of 500-1 million KVA. The total output of the above-mentioned 50 enterprises accounted for 84% of the total output of transformers in that year.
Under the situation of reform and opening up, the transformer manufacturing industry has been booming, new production enterprises continue to emerge, and the production scale continues to expand. But in recent years, the phenomenon of low-level repeated construction is more serious, the number of joint ventures is gradually increasing, and the import products are increasing, so the market competition is very fierce.
At present, the production capacity of the whole industry greatly exceeds the market demand. In order to develop in the fierce market competition, the transformer industry must make great efforts in developing new products, and develop in the direction of safety, reliability, intelligence, low loss, low noise, light weight and large capacity, so as to meet the needs of different users. Large transformers are developing towards high voltage and large capacity. During the Tenth Five Year Plan period, the company mainly aimed at developing product varieties and vigorously carried out asset optimization to meet the needs of domestic and foreign markets.
China's Transformer exports are mainly in Southeast Asia, the Middle East and neighboring countries. Among the imported transformers, high voltage and large capacity transformers still account for a large proportion. About 2 / 3 of domestic 500kV transformers are imported products, while only 1 / 3 of domestic 500kV transformers. The annual export output of transformers are 14.83 million KVA, 7.74 million KVA, 5.26 million KVA and 11.35 million KVA respectively. The annual export output value is 400-600 million yuan, and the export earnings are 43-69 million US dollars. According to the situation of the transformer industry, this report makes a detailed exposition, which is reasonable and worthy of reference.
