Here is more information about GFDD470-110 cooling fan:

Technical Parameter

  • input voltage: 220V
  • power (output): 50W
  • air volume: larger, exact value varies by manufacturer
  • static (in a signal): Low noise design for smooth operation
  • Operating Temperature Range: -40℃~75℃
  • Installation: Usually installed on both sides of the lower part of the transformer coil, blowing cold air directly into the transformer's high and low voltage cooling ducts.
  • material (that sth is made of): High-quality materials with good corrosion resistance

Product Features

  • Highly efficient heat dissipation: By increasing the diameter of the wind impeller, the airflow is significantly increased, effectively reducing the temperature of the transformer.
  • low noise: The noise elimination parts are added to the air outlet to effectively control the noise generated by the high-speed airflow.
  • structurally sound: Fully enclosed design prevents foreign objects from entering and reduces the risk of failure.
  • high reliability: Adopting famous brand motors and high quality bearings to ensure long-term stable operation.
  • adaptableThe dry-type transformer can be adapted to a variety of capacities to meet the needs of different users.

application scenario

  • Dry-type transformer cooling: It is mainly used for forced air cooling of dry-type transformers, which can significantly improve the heat dissipation efficiency of the transformer and prolong its service life.
  • run at increased capacity: With the use of this fan, the output power of the dry-type transformer can be increased by 40-50%, thus increasing the carrying capacity of the transformer.
  • Other equipment coolingIt can also be used for cooling of high and low voltage distribution cabinets, switch cabinets, electronic equipment, and so on.

Installation and use

  • mounting position: Usually mounted on both sides of the lower part of the transformer coil to ensure that cold air is blown directly into the cooling ducts.
  • Environmental requirements: The gas passing through the fan should be free of strong acids, alkalis and various solutions to avoid sand, dust and other debris from entering the interior of the fan.
  • Maintenance: Regularly check the operating status of the fan, clean up dust and debris to ensure normal operation of the fan.

How it works:

This series cooling fan is used in dry type transformer, the fan is placed on both sides of the lower part of the transformer coil, blowing the cold air directly into the coil of the transformer high and low pressure cooling air ducts, the heat dissipation effect is obvious, which can guarantee the normal operation of the transformer and prolong its service life. (Fan start, stop and transformer over-temperature alarm, over-temperature tripping and other functions are provided by the temperature control device).
