Demand For Dry-type Transformers Is Increasing
- Mar 13, 2018 -

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 China's market share is relatively low, but with its own excellent application conditions and performance, the proportion of dry transformers in total output of transformers will rise to a certain extent.

It is estimated that by 2020, China's dry market share will reach about 50%, which is equivalent to the proportion of developed countries. Therefore, China's dry market has a long way to go.


China's dry - changing 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 distribution transformer with short circuit test capacity is 2500kVA and 10/0.4kv.

The dry power transformer with the maximum capacity of short circuit test is 16000kVA and 35/10kv.


In 2012, the output of dry-type transformers in China was 1860719,000 kva, which is one of the largest dry transformers in the world.

Dry transformers are now widely used in power stations, factories, hospitals and almost all other electrical systems.

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.
