Transformer Industry In The Future Development Trend
- Sep 23, 2017 -

Transformer is a device that utilizes electromagnetic mutual inductance, transform voltage, current and impedance. The most basic form of the transformer, including two groups of wires around the wire, and together in an inductive way together.

As China's economy continues to grow rapidly, electricity demand continues to grow rapidly. In 2011 the national total electricity consumption of 4.69 trillion kwh, up 11.7% over the previous year, consumer demand is still strong. Per capita electricity consumption of 3483 kilowatt hours, an increase of 351 kilowatt hours over the previous year, more than the world average. Today, the state has increased investment in power construction, activation of the transformer market, but at the same time, a large number of enterprises into the transformer industry, so that the rapid expansion of production capacity, some drawbacks began to gradually appear.

Transformer low operation, industry strength to be improved

China's large-scale transformer industry, the majority of small and medium enterprises. As of November 2008 statistics, China's transformer industry, a total of 1589 enterprises, more than 100 million industrial output value of more than 130, the number of employees more than 2,000 people only 16, the market power is too scattered, not yet fully formed " - small and medium enterprises "industrial system.

At the same time, most of the transformer business has been operating in a low-cost environment, the phenomenon of excess capacity is particularly serious. China's annual demand for transformers are about 1.5 billion kVA, while the transformer industry capacity is about 3 billion kVA. Since 2009, the national power construction slowed down, the domestic demand for transformer has been reduced, especially the grid companies to use centralized bidding to purchase transformers, low-cost winning lead to fierce competition in the enterprise, and even the emergence of the transformer enterprises at the expense of product quality malicious competition The situation, the market order chaos.

"Overcapacity, the quality of hidden and more scattered industry," has become the transformer industry can not ignore the industry dilemma, how to break the dilemma, has been the industry's common thinking of the subject, and the national energy-saving emission reduction policy may be difficult Period of the transformer industry to provide an export.

Industry situation serious transformer breakthrough road

August 21, 2012, the State Council issued "energy-saving emission reduction," Twelfth Five-Year Plan "detailed draft, clear the" second five "during the specific objectives of energy-saving emission reduction and investment planning, requiring" second five " Power transformer losses, including no-load loss reduced by 10% to 13%, load loss reduced by 17% to 19%, which undoubtedly for the promotion of energy-saving transformers to provide policy support.

According to the national grid data disclosure, as of the end of 2011, the total number of distribution transformers running in the network is about 13.5 million units, of which S11 type and above energy-efficient distribution transformers for 2.94 million units, accounting for 21.8% of the total. It can be seen that the next few years, the national grid will have 78.2% of the transformers need to be replaced by S11 type or higher model. Moreover, the "elimination of high energy consumption transformer" is no longer "in the use of" the proposed terms. According to Zhao Yuejin, China's energy efficiency standards are mandatory standards, and need to eliminate the high energy consumption products will be listed in the "high energy consumption products out of catalog", the specific implementation of the provisions of the provision of guidance and basis.

Comprehensive above a variety of factors, the transformer business to do a good job to fight a long time to prepare for the war, the enterprises practicing internal strength, to carry out product manufacturing, to provide users with quality service and practical use of the program from the original single product supplier to the user Of the integrated service providers to change, thereby enhancing the added value of products and corporate profits, to achieve sustainable development of enterprises.
