　　A transformer is a device that USES electromagnetic mutual inductance to transform voltage, current and impedance. The basic form of a transformer consists of two groups of coils wound with wires, each of which is weighted by inductance.

　　With the sustained healthy and rapid development of China's economy, the demand for electricity continues to grow rapidly. In 2011, China's total electricity consumption was 4.69 trillion kilowatt-hours, an increase of 11.7 percent over the previous year. Per capita electricity consumption was 3,483 KWH, an increase of 351 KWH over the previous year and above the world average. Nowadays, China has increased the investment in power construction and transformer market. However, at the same time, a large number of enterprises have poured into the transformer industry, resulting in the rapid expansion of the industry's production capacity and some drawbacks have gradually emerged.

　　Transformer low - level operation, industrial strength to be improved

　　China's transformer industry scale is huge, small and medium-sized enterprises in the majority. By the statistics of November 2008, there are 1589 enterprises in China's transformer industry, only 130 of which have an industrial output value of more than 100 million, and 16 of which have more than 2,000 employees. Market forces are too dispersed, and the industrial system of "leading -- small and medium-sized enterprises" has not been completely formed.

　　At the same time, most transformer companies have been operating in a low efficiency environment, the phenomenon of overcapacity is particularly serious. China's annual transformer demand is around 1.5 billion kva, and the transformer industry capacity is about 3 billion kva. Since 2009, the speed of power construction in China has slowed down, and the demand for transformers in China has decreased. Especially, power grid enterprises have adopted centralized bidding to purchase transformers. Winning the bid at a low price has led to unprecedented fierce competition among enterprises.

　　"Excess capacity, hidden risks in quality and scattered industries" has become a dilemma that cannot be ignored in the whole transformer industry. How to break the dilemma has been a subject of common thinking among industry insiders. The policy of energy saving and emission reduction may provide an outlet for the transformer industry in a difficult period.

　　The industry situation is grim transformer breakout road

　　On August 21, 2012, the state council issued the "twelfth five-year" plan for energy conservation and emissions reduction, detailed and clear about the "twelfth five-year" period of energy saving and emission reduction targets and investment planning, requirement "twelfth five-year" period, reduce the loss of power transformer with no-load loss reduce 10% ~ 13%, reduced by 17% ~ 19% load loss, it provides policy support for the promotion of energy-saving transformer.

　　According to China's power grid data disclosure, by the end of 2011, the total number of distribution transformers operating in the network is about 13.5 million, among which 2.94 million are energy-saving distribution transformers of type S11 or above, accounting for 21.8% of the total. It can be seen that in the next few years, 78.2% of transformers in the power grid will need to be replaced with S11 or higher. Moreover, "eliminate high energy consumption transformer" is no longer a "look useless" recommendation. According to zhao yuejin, China's energy efficiency standards are mandatory standards, and the products that need to be eliminated will be listed in the "list of products that need to be eliminated" to provide guidance and basis for the specific implementation of the provisions.

　　Comprehensive above factors, transformer enterprises should always be prepared to fight, each enterprise practice internal work, to develop special products processing and manufacturing, to provide users with high-quality service and practical use, from a single supplier comprehensive service provider to the user's transformation, thus improve the added value of products and profits, achieve the sustainable development of the enterprise.
