Product Summary

The low noise fan for transformer, based machinery industry standard JB / T96421999 "Transformers fan”, is designed and manufactured jointly with the Institute of Fluid Dynamics of Zhejiang University, specially for the use of transformer cooler and radiator in large and heavy transformer. Fan blades adopt airfoil type in the material of die-casting aluminum. Compared with similar steel products, it has the characteristics of lighter weight, more stable performance, lower noise and so on. Blade design has been patented (patent number: 200410089164.2). Its protection class is IP55, and the fan structure is the axial flow impeller connected with the direct axis of outdoor three-phase asynchronous motor.


Product Characteristics

This series of fan design adopt the blade of half section airfoil type, and optimize the blade parameters, with characteristics of large air volume, high air pressure, low noise, high efficiency, long operating life and so on.

The blade is made of high strength and die-casting aluminum alloy, with light weight, corrosion resistance and other characteristics.

Impeller and motor with direct shaft connection, according to the different installation methods cooler and radiator, either horizontally or vertically hair.

Fans are provided with a safety net.

Motor is fully enclosed outdoor three-phase motors, internal overload thermistor temperature is 110 , protection class IP55, fans can continue to run.
