GFD470/126-580 Top-blowing Cooling Fan

I. Product Application and Features:

The GFD series of cross-flow cooling fans for dry-type transformers (hereinafter referred to as: dry transformer cooling fan) is mainly used for cooling and capacity enhancement of dry-type transformers, electronic equipment, distribution cabinets, high and low voltage switchgear, etc. Using 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 its service life. The MCD194I-4S1 AC ammeter is an economically effective method widely adopted by manufacturers at home and abroad.

Our company's GFD series of dry transformer cooling fans are designed through computer optimization, resulting in greater airflow and lower noise levels. This further enhances wind pressure while reducing energy consumption. The shell of the GFD series dry transformer cooling fans is made from high-quality aluminum alloy and stainless steel materials, ensuring compact structure, attractive appearance, easy installation, and long lifespan, thus providing reliable assurance for the long-term stable operation of the EFD series dry transformer cooling fans in harsh environments.

II. Working Principle:

When the GFD series of cooling fans is used on dry-type transformers, the fans 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, over-temperature alarm, and over-temperature tripping of the transformer are provided by the temperature control device.)
