The amorphous alloy transformer market has entered a period of rapid growth. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. In electrical equipment and radio circuits, they are often used as up-and-down voltage, matching impedance, safety isolation, etc. At present, there are more than 1200 transformer manufacturers in China, which can produce transformers, transformers, reactors, voltage regulators and their supporting components. In recent years, China's electricity demand has increased rapidly, and the high-speed construction and investment of power grid have stimulated the market demand of transmission and transformation equipment. The huge power construction funds bring opportunities and challenges to the transformer industry (including transformer, transformer, reactor, component manufacturer), and promote the rapid development of the transformer industry. Data from China Business Intelligence Network show that in the first three quarters of 2011, China's transformer output exceeded 1.1 billion kilovolt-amperes, an increase of 13.9% over the same period last year. With the deepening of power grid reconstruction project and the acceleration of power grid upgrade, transformer production in China will still maintain a relatively fast growth rate. It is estimated that by 2015, the output of transformers in China will exceed 2 billion KVA. With the deepening of China's energy-saving and consumption-reducing policies, the State encourages the development of energy-saving, low noise, intelligent distribution transformer products. Distribution transformers with high energy consumption are facing the need of technology upgrading and renewal, and will be gradually replaced by transformers with energy saving, material saving, environmental protection and low noise in the future. Amorphous alloy transformer has both energy saving and economy. Its remarkable feature is that no-load loss is very low, which meets the requirements of national industrial policy and energy saving and consumption reduction of power grid. It is the most advanced energy-saving effect and relatively economical distribution transformer product at present. After solving the problem of noise, the products are generally applicable to all kinds of places in cities and rural areas.
