Product General
Transverse-flow type ventilators for dry-type transformers
Dry Type Transformers cross-flow cooling fan mainly for dry-type transformer cooling capacity enlargement, electronic equipment, power distribution equipment and high-low voltage switch cabinet force air cooling. With this fan, it will enlarge capacity 40~50%.
The product designed strictly in accordance with JB/T8971-1999 "dry-type transformer with cross-flow cooling fan". Motor stator and rotor core using quality steel; Low noise bearings; Impeller electrophoresis using aluminum alloy surface treatment, and through the refinement of Balancing adjustments; Around end-plate using stainless steel plate metal forming.
progressive Wind boards, panels and wind up wind deflector using aluminum alloy composition profile fixating bandage.
Model Note

Technical parameters
Note: Others is available accordingly.
The installation steps
It is installed under the dry-type transformers next to pieces andunder the cooling fan out of the wind angle (the angle between the level of about 135 °) and the location of storm out.
The cooling fan usually installed under the feet end-support.
Installed its air inlets (referring to the lateral aspect), and closed the barrier to maintain a certain distance (generally less than 10cm).
