GFDD358-155 is a dry-type transformer cross-flow typeCooling Fans. The following is a specific description of this model of fan:
- Model MeaningGFDD means cross-flow cooling fan for top-blown dry-type transformers, 358 means the total length of the fan is 358mm, 155 means the diameter of the impeller is 155mm.
- specificities::
- high efficiency: Adopting cross-flow design, it can provide larger air volume and better heat dissipation effect, effectively reducing the temperature rise of the transformer.
- compact design: Compact fan design with small footprint for easy installation and maintenance.
- low noise: By optimizing the blade design, the noise level of the turbine is reduced for quieter operation.
- operational stability: It is made of high quality materials with good resistance to high temperature and corrosion, which can ensure long-term stable operation.
- Easy to installThe fans are designed with standardized interfaces for easy connection to dry-type transformers, making the installation process quick and easy.
- Working Principle: The fans are placed on both sides of the lower part of the coil of the dry-type transformer, blowing the cold air directly into the coil of the transformer high and low pressure cooling air ducts, to improve the heat dissipation efficiency of the transformer by means of forced air convection, to ensure the normal operation of the transformer and to extend its service life.
- Application Areas: It is mainly used for the cooling of dry-type transformers, including those in power systems, industry and civil buildings. It is also suitable for power electronic equipment, reactors, distribution and switchgear cabinets, industrial automation equipment and other occasions where forced cooling is required.
- Technical ParameterTake GFD(S)358-155 as an example, its working voltage is single/three-phase 220/380V, power is 0.48/0.22kW, rotating speed is 1,400r/min, air volume is 630-800m3/hour, and the noise level is less than 57dB.
