Transformers are devices that change ac voltage according to the principle of electromagnetic induction, electrical devices and rf circuits, used to raise voltage, impedance matching. At present, China has a certain scale of transformer manufacturers more than one thousand, they produce transformers, reactors, voltage regulators and supporting components and other products.

In recent years, China's power demand has increased rapidly, high-speed network construction and investment drive the power transmission and transformation equipment market. Large power transformer industry (including transformer, reactor, component plant) construction funds brought opportunities and challenges, promote the transformer industry has been rapid development. Business Intelligence Data Network, in the first three quarters of 2011, China had a billion kVA transformer output, growing at an annual rate of 13%. With the development of power network renovation projects and the acceleration of power network upgrading, China's transformer production will continue to grow rapidly. It is estimated that by 2015, China's transformer output will exceed 2 billion kVA.

With the deepening of China's energy conservation policy, the country encourages the development of energy saving, low noise, intelligent distribution transformers. High energy consumption distribution transformer, facing the demand of technology upgrading and upgrading, will gradually become energy saving, material saving, environmental protection, low noise transformer replaced in the future. As an amorphous alloy transformer of energy and economy, it has very low no-load loss, conforms to the characteristics of national industrial policy and power energy saving requirements, and is the most advanced energy-saving effect in China at present, and the use cost is also relatively economical distribution transformer products. In solving the problem of noise, the products are widely used in urban and rural areas.

The report shows that urban and rural distribution networks continue to accelerate the development of power grid construction and renovation, and the transformer market demand is expected to maintain strong growth. In 2010, the amorphous alloy transformer in China was about 1.8 billion yuan. The market promotion of amorphous alloy transformer accelerated the market scale and the application proportion of products gradually increased. In the next ten years, the market capacity of amorphous alloy transformer will reach 10 billion YUAN, and the annual market capacity will exceed 1 billion yuan, which is a huge market space.

The state will encourage the development of energy-efficient, low noise, intelligent distribution transformer products. In the same industry, large enterprises with large operation scale and strong r&d ability will face more development opportunities.
