GFD470/150-1050 Top-blow Cooling Fan
I. Product Purpose and Features:
The GFD series of cross-flow cooling fans for dry-type transformers (hereinafter referred to as: dry transformer cooling fans) are mainly used for cooling and capacity enhancement in dry-type transformers, electronic equipment, distribution cabinets, high and low voltage switch cabinets, etc. The use of this series of cooling fans can increase the output power of a dry-type transformer by 40-50%, greatly enhancing its load-carrying capacity and extending the service life of the dry-type transformer. This is the most economical and effective method widely adopted by domestic and international manufacturers.
Our company's GFD series of dry transformer cooling fans have been optimized through computer design, providing greater airflow and lower noise, further improving wind pressure and reducing energy consumption. The shell of the GFD series dry transformer cooling fan uses high-quality aluminum alloy materials and stainless steel, with a compact structure, beautiful appearance, easy installation, and long service life, ensuring the stable operation of the EFD series dry transformer cooling fans in harsh environments over the long term.
II. Working Principle:
When the GFD series cooling fans are used for dry-type transformers, they are placed on both sides below the transformer coil, directly blowing cold air into the high and low voltage cooling channels of the transformer coil. The heat dissipation effect is significant, ensuring the normal operation of the transformer and extending its service life. (Functions such as starting/stopping the fan, overheating alarms, and overheating trips are provided by temperature control devices.)
