11kv three-phase oil immersed distribution transformer

11kv three-phase oil immersed distribution transformer
Everpower Three-Phase Transformers are in accordance with IEC 60076 Standard, or National Standard GB1094 "Power Transformer". Special care is taken in the choice of high quality material, manufacturing technology and construction, so that the performance characteristics can match with those of the highest standard of the international market. Low loss and high efficiency means substantial saving in energy and low operation cost. Therefore they are widely used in places where requirement on voltage quality is emphasized, such as institutes, buildings, hotels, hospital and factories.
