Casing of Transformer
Casing of Transformer
Product Introduction
It is not necessary for general dry-type transformer to equip casing, means the protective degree is IP00, if need to be equipped with casing, protective degree is IP20, Casing is constituted by a safety shield to prevent accidental electrocution. Under the conditionof having dripping water, the transformer can be equipped with casing of that protective level is IP23. According to users  special requirements, we can provide casing with IP54 protective level.
Temperature Controlling and Cooling Devices
Temperature controlling device

Transformer adopts BWDK temperature controlling device, temperature measuring component is in the top of low voltage winding that can detect automatically and cyclically display working temperature of three-phase winding. When the temperature of winding reaches setting value , thermometer can automatically start the fan, stop the fan, signal transfer output, tripping output, etc.
Air cooling device
Transformer is equipped with dedicated Axial flow cooling fan, transformers capacity can be increased by 40%, even more under the condition of forced- air cooling.
