Product
The low noise fan fory transformer is developed. Designed and manufacture together with Zhejiang university hydrokinetics graduates school according to the mechanical sector standard JB/T96421999 《Transformer Fan》. The low noise fan used by transformer is specially used on the big and middle-sized transformer cooler and radiator. The vane of this low noise fan adopts the aerofoil type and its material adopts the die-casting aluminum. Compared with the same type steeliness products. The low noise fan used transformer has several characteristics such as the light weight, stable performance and low noise etc. the protecting grade of this low noise fan is IP55 and its fan structure is: straight axis link by the axis flowing type impeller with the outdoor three different phase electromotor.
