Power demand rises, transformer industry gains rapid develop

With the rapid development of our national economy, the demand for electric power is increasing day by day. As the main equipment transformer in power transmission and transformation system, it has been developed by leaps and bounds. It is learned that the power transformer industry is a typical investment-driven industry, in the case of only considering the domestic market, domestic power investment determines the rise and fall of the transformer industry. Power transformer is a static electrical equipment, is used to a certain number of AC voltage (current) into the same frequency of another or several values of different voltage (current) equipment. Alternating magnetic flux is produced when the primary winding is fed with alternating current, which is fed through the iron core to induce an alternating electromotive force in the secondary winding. The magnitude of the electromotive force is related to the number of turns in the primary and Secondary Windings, i. e. the voltage is proportional to the number of turns. The raw materials for transformer production mainly include oriented silicon steel sheet, insulation material, transformer oil and electromagnetic wire (mainly copper) . The cost of oriented silicon steel is about 40% . Therefore, the price of oriented silicon steel has a great influence on the gross profit rate of transformer manufacturers. From the perspective of industrial chain, upstream main raw materials such as oriented silicon steel, copper and so on, its price trend is favorable to the transformer industry, promoting the overall profitability of the industry tends to rise. The power transformer industry is a typical investment-driven industry. Considering only the domestic market, domestic power investment determines the rise and fall of the transformer industry, the power plant and the power grid constitute the transformer demand of the two categories of customers. Especially the power grid companies, from the highest-end 1000kV UHV transformer to the lowest 10kV distribution transformer has a huge demand. China's Shenyang Transformer Factory, Xi'an Transformer Factory and Baoding Transformer factory have all produced 500 KV class power transformers in batches, operating in 500 KV system, the longest has been more than 17 years, after more than 10 years of continuous improvement, the operation index of the utility model is exactly the same as that of the imported transformer, and the total output is 150GVA. According to the report on market demand forecast and investment strategic planning analysis of China's power transformer industry from 2015 to 2020 released by the forward-looking Industry Research Institute, the total assets of China's power transformer industry amounted to 251.941 billion yuan from January to August 2014, it was up 23.0% year on year. In 2013, the total assets of China's power transformer industry reached 207.678 billion yuan, up 21.3 percent year-on-year. With the rapid development of China's national economy, the demand for power is also increasing, as the main equipment transformer in power transmission and distribution system has also been developed. In order to meet the market demand, many manufacturers have continuously improved the product structure, improved the product performance, imported advanced production technology and equipment from abroad, and made unremitting efforts in the exploration of new processes and new materials, in order to improve the quality and reliability of products, has made considerable progress. On the other hand, in the global competition, although our country already has considerable strength in the small capacity aspect and occupies an important position in the international market, but in the high-capacity, ultra-high-capacity transformer aspect, china's technical strength is still very weak, which has caused our country to be unable to enter the markets of high-capacity and ultra-high-capacity transformers in developed countries in Europe and the United States, which will hinder the development of China's transformer industry in the future, requires a great deal of attention. With the sustained, healthy and high-speed development of China's economy, power demand and input continued to grow rapidly, China's power transmission and distribution industry market prospects are still good. The development of electric power has injected powerful power into the development of the whole power transmission and distribution equipment industry. At present, China's annual procurement of power transmission and distribution equipment accounts for 32% of the world's total, and has become a valuable target market for its counterparts in the world.
