Future development trend of transformer industry.
- Jan 11, 2018 -

A transformer is a device that USES electromagnetic mutual inductance to transform voltage, current and impedance.

The most basic form of a transformer consists of two sets of coils of wire, which are called together by inductance.

With the sustained and healthy development of China's economy, the demand for electricity continues to grow rapidly.

In 2011, the total electricity consumption of the whole country was 4.69 trillion KWH, an increase of 11.7% over the previous year, and consumer demand was still strong.

Per capita electricity consumption is 3,483 KWH, an increase of 351 KWH over the previous year, exceeding the world average.

Now, the state increased investment of electric power construction, activate the transformer market, at the same time, however, a large number of enterprises into the transformer industry, make the industry rapidly expanding capacity, some disadvantages also begins to show itself.

Transformer low operation, industrial strength to be improved.

China's transformer industry is large and small and medium-sized enterprises.

As of November 2008, it had a total of 1589 enterprises in transformer industry in our country, more than 100 million gross industrial output value of more than 100 million only, only 16 of more than 2000 employees, market forces are too scattered, "leading" - small and medium enterprises has not yet fully formed the industrial system.

At the same time, most of the transformer enterprises have been operating in low efficiency environment, and the phenomenon of excess capacity is especially serious.

The annual transformer demand in China is about 1.5 billion kva, and the transformer industry capacity is about 3 billion kva.

Slowed since 2009, the state power construction, demand of domestic transformer decreases, especially the way that power grid enterprises to adopt centralized bid procurement transformer, low bid enterprises unprecedented fierce competition, appear even the transformer enterprise sacrifice of the vicious competition in product quality, market order confusion.

"Excess production capacity, quality hidden trouble, more scattered industry", has become the whole transformer industry can't ignore the industry, how to break the dilemma, is always a problem in the industry of common thinking, and the national policy of energy conservation and emissions reduction may be able to in a difficult time of transformer industry provide a exports.

The industry situation of severe 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.

Disclosed according to the national grid data, by the end of 2011, the total number of distribution transformer in the network run of about 13.5 million units, including S11 type distribution transformer for 2.94 million units, and more energy-efficient accounted for 21.8% of the total.

It can be seen that in the next few years, the state grid will have 78.2% of the transformer needs to be replaced by the S11 or higher model.

Moreover, "elimination of high-energy transformer" is no longer a "useless" suggestion clause.

According to yue-jin zhao, efficiency standards in our country belongs to the compulsory standards, and to eliminate the high energy consumption of products will be listed in "energy-intensive products catalog", provide guidance and basis for the specific terms of the practice.

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.
