During the second five, China's environmental protection investment will reach 3.1 trillion yuan, 2015, China's energy-saving environmental protection industry output will reach 5.3 trillion yuan, equivalent to 8% to 10% of GDP over the same period. High-voltage inverter as saving energy and reducing The main force of the platoon and pioneer, there is a huge market demand in the future. High-voltage inverter involves a very wide area, including electricity, metallurgy, coal, petrochemical and other industries, including electricity, metallurgy, cement and other industries are increasing share of each year. In 2011, the oil, gas, mining, cement and petrochemical industries covered nearly 50% of the domestic market of high-voltage frequency converters. The market size of the cement industry reached 1.201 billion yuan, making it the largest market in the four industries 16%. These industries are mostly high energy-consuming industries, energy-saving emission reduction tasks to be solved. As the high-voltage frequency converter less affected by the economic cycle, influenced by the relevant national policies. Under the twelfth five-year energy-saving emission reduction in China under tremendous pressure, high-voltage inverter market opened up room for appreciation. At present, high-voltage inverter is used in fan, water pump, compressor, rolling mill and other equipment, it can not only improve the process, extend the service life of equipment, improve work efficiency, the most important thing is that it can save energy and reduce consumption. As China further expands its consumption economy, investment will continue to increase. As a result, factories and integrated power applications in many industries require energy-saving measures. Second, power control opportunities in the Asian OEM, process and heavy industry markets are expected to provide significant growth potential for this acquisition. High-voltage frequency converters are an integral part of many large-scale automation projects. At present, the strength of supporting industries in China's inverters is relatively weak. Generally speaking, domestic brands have a gap with foreign brands both in terms of technology, processing and manufacturing, industrial design, etc., especially with Siemens and ABB The gap between the giants even more obvious. However, with the rise of local brands, the market share of domestic inverter manufacturers is gradually expanding. Especially in recent years, there has been a trend of accelerating the substitution of foreign brands. In recent years, domestic brands of inverter manufacturers already have a certain series of products, digital control system also gradually covered in the industry, the extension of the industrial chain also allows the structure has a balanced development trend. With the rise of domestic manufacturers of high-voltage frequency converters, the pattern of monopolization of imported products by foreign manufacturers has been broken.
