The Development Prospects of Dry Type Transformers In China

In recent twenty years, with further development of the international economy, dry type transformers have made a great progress, especially in distribution transformers. According to statistics, the use of dry type transformers accounts for 40% in Europe and the United states and other developed countries. In China, it is up to 50%. It can be seen that China is one of the largest country of selling dry type transformers in the world.

Currently, in China, as the step of urban power network construction speeds up, generating capacity and power consumption are increasing by the day. It is why dry type transformers have been growing popularity in China.
The dry type transformer adopts air convection to achieve the natural cooling effect. It is widely used in local lighting and electronic circuitry. Comparing to the oil filled transformer, dry type transformer is not immersed in oil, and is cooled by air convection or by fans, so it can not cause fire, explosion, pollution of environment and other problems. Also, this transformer has three forms: open type, closed type and cast type. The open type which is direct exposure to air is one of the mostly used form and is widely used in clean and dry indoor. The closed type mainly exist in the closed area and isn't contact with the air directly for the poor heat dissipation condition. The last is the cast type which uses exposy resin and other resins as main insulation. It is of simple structure, small size, so it applies to small transformer.
Furthermore, the dry type transformers have many performance features. First of all, it adopts advanced technology both at home and abroad. It has high mechanical strength, the ability to short-circuit resistance, good heat stability, high reliability, as well as long working life. Besides, this transformer has advantages of good moisture resistant. It can be used under long-term operation in harsh environments. What's more, it is equipped with measuring temperature system which adopts intelligient control system. Thus, it can adjust the temperature automotically during working. Not only that, the dry type transformer is small size, light weight, so it takes up small space and it only needs lower installation costs.
With popularization and application of dry type transformers, dry type transformer manufacturer also obtains great progress. In order to attract more customers, dry type transformer manufacturer insures that their dry type transformers can require minimun maintenance and provide long years of reliable trouble-free service. All in all, dry type transformers in China have the broad prospects for development.
