What is the information do you know about the Dry Type Transformer?

The Dry Type Transformer is mainly composed of an iron core composed of silicon steel sheets and a coil cast by epoxy resin. An insulating tube is placed between the high and low voltage coils to increase electrical insulation. Then, the coil is supported and constrained by spacers and its parts are overlapped by fasteners. All of them have anti-loose properties.

What are the structural features of Dry Type Transformer?

-Temperature control system

The safe operation and service life of Dry Type Transformer largely depend on the safety and reliability of transformer winding insulation.

-Cooling mode

Dry Type Transformer is divided into natural air cooling (an) and forced air cooling (AF). In case of natural air cooling, the transformer can operate continuously for a long time under the rated capacity. When forced air cooling, the output capacity of the transformer can be increased by 50%. It is applicable to intermittent overload operation or emergency accident overload operation; As the load loss and impedance voltage increase greatly during overload, it is in non economic operation state, so it shall not be in continuous overload operation for a long time.

9. Noise coefficient: ≤30dB.

What is the difference between Dry Type Transformer and inverter?

Inverter: It can adjust the required power frequency (50hz, 60hz, etc.) to meet our special needs for electricity.

Transformer: Generally, it is a "step-down device", which is commonly found near communities or factories. Its function is to reduce the ultra-high voltage to the normal electricity voltage of our residents to meet people's daily electricity consumption.

Dry-type transformers and oil-immersed transformers are the two most commonly used transformers. Compared with oil-immersed transformers, dry-type transformers have better fire resistance and are mostly used in places requiring higher fire protection levels, such as hospitals, airports, stations, etc. On the other hand, the price is higher, and there are certain requirements for the ambient environment, such as not being too humid, not having too much dust and dirt, etc. In addition, the operational maturity of dry-type transformers is not as good as that of oil-immersed transformers.

Dry Type Transformer has an indispensable position in the current industrial production process. hejiang Zhegui Electric Co., Ltd has committed to providing the most suitable Dry Type Transformers at a reasonable price.
