S11 oil immersed three phase transformer

S11 oil immersed three phase transformer Advanced design and reasonable structure, easy installation and good economic performa

S11 oil immersed three phase transformer 

 Usage environment

1. The altitude of installation could not be over 1000m2. Environment temperature: . Highest temperature: +40 degree centigrade. Highest daily average temperature: +30 degree centigrade. Highest yearly average temperature: +20 degree centigrade. Lowest outdoor temperature: -25 degree centigrade

Features

1. Active part (core and winding assembly) adopt fastness measure and use locknut, which can bear the shake during transportation. 2. Dry windings and core in vacuum; Using vacuum filtrating and impregnating oil techniques make the humidity in box to be least. 3. Advanced design and reasonable structure, small size, light weight, easy installation, and good economic performance.
