It is applied to crosscurrent top-blow cooling fan which has characteristics of low noise, High wind pressure and good looking, Etc, The fan improves the overload capability of the transformer. The intelligent thermal controller improves the reliability of the operation of the transformer.
The grade 110KV transformer products of our company have formed to be standard configuration and at the same time we launched new products such as structure of self-cooling, Maintenance-free and welded tank rim, The features of which are maintenance-free, High reliability, High impedance, Low loss, low noise, Low temperature rise, Low pd, That is "1-free, 2-high, 4-low". The products SFZ-31500/110 and SZ10-M-50000/110 Firstly passed necessary short current test in1997 and 2000 and it made this product always stand at the advanced lever in grade 110KV in china.
