    In the community why did not see buried box type substation

    According to the different structure and the different components, the box-type substation can be divided into two typical styles: European box-type transformer and American box-type transformer. From the structure of high and low voltage switch cabinet, transformer composition, this type of box substation is called European box transformer. Metaphor for high and low voltage switchgear, transformer built a house. In the structure of the load switch, ring network switch and fuse structure simplified into the transformer tank immersed in oil, lightning arrester also USES oil-immersed zinc oxide arrester, transformer remove the oil cushion, oil tank and radiator exposed to the air, this type of box substation is called the American box transformer. It's like hanging a box next to a transformer. ...
