Development of power transformer

In the past decade of development, China's rapid development of power construction, impressive. Among them, the power generation capacity of high-speed growth, power grid construction speed by leaps and bounds, power structure adjustment and continuous optimization, a substantial increase in the level of technology and equipment, energy-saving emission reduction effect is remarkable, power construction to achieve a leap-forward development. This is a stable and rapid development of China's economic and social development has provided a powerful driving force to improve people's lives has played an important support and security role.

According to the National Bureau of Statistics data, from 2007 to 2011, the sales scale of the ac power transformer manufacturing industry has been expanding and the sales revenue has increased by more than 13% annually. The sales revenue in 2011 reached 1,784.36 billion yuan, up 16.53% over the same period of last year. Billion, down 5.43% year on year. Overall, in 2011, China's power transformer manufacturing industry developed stable, but profitability has declined. For the sake of the global economic environment, China's future may increase the proportion of renewable energy. State Grid, South Network are studying light DC, these are new trends, the transformer industry will bring new areas of development. And power transformers in the market development and use of more and more widely in the technical and quality of some of the well-known enterprises also stand out For example, a group of investment over the years the company has been committed to the development of national electrical industry, and many scientific research institutes, Colleges and universities and international industry giants to establish close cooperation, the establishment of the "Shanghai Electric Science Institute," professional research and development, production transmission and distribution control equipment, high and low voltage electrical components, smart electrical and other goods, has developed a "intelligent PLC control (B) H15-M, S (the total screen "and" intelligent complete sets of switch control "and other high and low voltage electrical components; and Shenyang Transformer Research Institute, research and development, production of high and low voltage transformer products, B) H16-M amorphous alloy roll core power transformer, SC9, SCB9, SC10, SCB10 series resin insulated dry-type transformers, SG10 type H-class insulated dry-type power transformers, SGB11- r roll core h-class non-encapsulated Coil dry power transformers, 10kV class S9, S11 series oil-immersed power transformers, 35kV class S9- □ - □ series oil-immersed power transformers and other products And at the same time R & D and production of the transformer production foil winding machine, amorphous alloy shearing machine, high and low pressure winding machine and other special machinery and equipment; and the United States General Electric Company (GE) strong combination, to create the Asia-Pacific region's largest and most professional Marine switch equipment and low-voltage electrical equipment, has developed the GEA plus2.0, Modula plus, Modula 630k, marine transformers(50kva power transformer), marine box-type substation, marine electrical automation equipment, tunnel dedicated distribution cabinet and other products.
