GFD Series Crossflow for Side-blown Dry-type TransformersCooling Fans(Hereinafter referred to as: dry-type transformer cross-flow cooling fan) is mainly used for dry-type transformer cooling capacity increase, and electronic equipment, distribution cabinet, high and low voltage switchgear and other forced air cooling. Dry-type transformer with this fan cooling, can increase capacity 40 ~ 50% operation, thus greatly improving the carrying capacity of dry-type transformer, and prolong the service life of dry-type transformer, is the domestic and foreign manufacturers commonly used economic and effective way.

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).
