Development Of Dry Type Transformer
- Nov 03, 2017 -

According to the analysis report on the market demand forecast and investment strategy of China's dry transformer industry 2013-2017, China has become the largest country in the world with the largest number of dry - to-produce sales.At present abroad of all kinds of high and low voltage electrical products, occupy the domestic market, some of the important only after the dry type transformer from the end of the 20th century, almost no imported from abroad, in the domestic key projects and major projects, hard abroad do change.

At present, the construction of urban and rural power grids is accelerating, and China's electricity generation and power consumption are increasing day by day.Generally speaking, each additional 1kW of generating capacity requires an increase of 11kVA transformer total capacity;Among them, Satons distribution transformers account for about 1/3-1/2 of total transformer capacity.It is estimated that the dry-type distribution transformer accounts for 1/5-1/4 of the total distribution transformer.Driven by the investment in the construction of power grids, the transformer industry is relatively good, and the output will maintain a growth rate of around 20% after 2010.Structure change, according to the historical experience and transformer voltage grade distribution transformer ratio at about 40%, according to the proportion of 40%, this year our country new dry type transformer output will reach about 200 million KVA.

Over the past 20 years, with the development of world economy, dry obtained a rapid development in the world, especially in distribution transformer, do change the proportion of more and more big, according to statistics, in Europe and the United States and other developed countries, it has accounted for 40 ~ 50%.From production point of view, our country for the second time since 1989 after the reform of city network, the output of dry type transformer has increased significantly, from the 1990 s, the growth rate is roughly 20% each year, the total output of 1999 are close to ten thousand MVA (this value has been more than 10 years ago predicted four thousand five hundred MVA), and in 2002 the total output of twenty thousand MVA, 2004 already amounted to thirty-two thousand MVA.This rate of growth is unprecedented in the world.

From the above data shows, at present our country has become the world's one of the largest country in the dry type variable volume, regardless of size, products in the factory capacity, voltage, etc, have been in the world leading level.
