The Demand For Dry Transformers Is Increasing
- Sep 29, 2017 -

In the development of our country current situation, the dry type transformer in the large and medium sized cities accounted for 15% of an average of about 20%, and in Beijing, Shanghai, guangzhou, shenzhen and other cities, accounted for about 50%, but as a result of rural power distribution network in our country the application of dry type transformer is relatively small, therefore, on the whole, dry type transformer of transformer used in 10-15%.


Although the market share of our country is relatively low, but with its own good application condition and performance, the proportion of dry transformer in total output of transformer will rise to a certain extent.

It is estimated that by 2020, the market share of China's dry change will reach about 50%, which is comparable to that of developed countries, so there is still a long way to go in China's dry-change market.


China's dry-change technology has reached the advanced level of the world


Forward-looking industry research institute "in 2013-2017 China's dry type transformer industry market demand forecast and investment strategy analysis report, according to the dry transformer are four kinds of structure: the epoxy resin casting, stuffed pouring, around the package, immersion type.

At present, widely used in Europe and the United States open ventilated dry type transformer class H is based on immersion type learned the winding and the structure characteristics and USES the Nomex paper developed a new type of class H after dry, because the price is high, in our country has not been popularized.


At present, the largest dry-type distribution transformer with short circuit test in China is 2500kVA, 10/0.4 kV.

The largest dry type power transformer with short circuit test capacity is 16000kVA, 35/10kv.


In 2012, the production of dry transformers in China was 18607.19 million kva, which was one of the largest sales of dry transformers in the world.

Dry transformers are now widely used in almost all electric power plants, factories and hospitals.

With low noise (below 2500 kva substation transformer noise has been controlled within 50 db), the energy conservation (no-load loss reduce 25%) of the SC (B) 9 series of popularization and application, makes China's performance of the dry type transformer and its manufacturing technology has reached the world advanced level.

Although our country's development of dry type transformer, it is a long road but in policy and technology under the guidance and development of dry type transformer is bound to broaden the market, have a place in the international market gradually.
