Tension class OMZh series transformers to 27 kV power lowering with natural oil cooling, included in the alternating current main with a frequency of 50 Hz, are intended for transformation of the electric power in networks of power supply systems.
The transformer consists of active part, a tank, a cover with conclusions of BH and HH. The active part is rigidly connected to a cover of a tank and consists of a magnetic conductor with windings, the lower and top yarmovy beams, withdrawal of BH and HH. The magnetic conductor of the transformer of rod type is built from holodnokatanny electrotechnical steel. Windings are multilayered cylindrical. The transformer tank welded, consists of the top frame, the feedwell, a bottom with the plates welded on it. In the lower part of a tank there is a knot of grounding and a drain stopper. On a tank the plate with technical characteristics of the transformer is fixed.
On a cover of the transformer inputs of BH and HH, an earring for raising of the transformer, the thermometer frame case, a maslorasshiritel are mounted.
