Product Description

Dry Type Transformer for Airproof Places


Dry type transformer, also called dry type distribution transformer or dry type power transformer, is a kind of voltage transformer utilizes air cooling method to reduce its working temperature. Compared with oil immersed transformer, dry type transformer is kind of transformer whose iron core and winding are not immersed in the insulation oil. The cooling methods of dry type transformer are divided into natural air cooling (AN) and forced air cooling (AF). When in the condition of natural air cooling, dry type transformer can be operated long-term continuously under the rated capacity. When in the condition of forced air cooling, the output capacity of dry type transformer can increase by 50%. Dry type transformers are widely used in local lighting, high-rise buildings, airports, places with mechanical equipment, etc.

Low loss, low noise, obvious energy saving effect.
Safety, fireproof, no pollution, can be directly run in the load center.
Excellent heat dissipation performance, strong loading capacity, the operating capacity can be increased when in condition of forced air cooling.
Excellent moisture resistance performance, transformer can adapt to high humidity and other harsh environments.
Adopted the international advanced technology, transformer features high mechanical strength, strong ability of anti short circuit, small partial discharge, good thermal stability, high reliability and long service life.
Dry type transformer can be equipped with completed temperature detection and protection system. Adopted intelligent signal temperature control system, transformer can automatically detect, display the working temperature of the three-phase winding, automatically start and stop the fan, at the same time, it can set up the function of warning, tripping and so on.
Application: 
With excellent fireproof performance, dry type transformers are usually used for places where need fireproof and explosion-proof, such as large buildings, high-rise buildings, local lighting, airports, or places with mechanical equipment. At the same time, dry type transformer can also be installed in the center load area to reduce the voltage loss and electrical power loss.
