TRASFORMER TANK

摘要

The present invention relates to an electrical box for a transformer. A lower casing member and an upper casing member are connected in the electrical box for a transformer. The present invention minimizes an area for installing a transformer by reinforcing the electrical box for a connection part between the lower casing member and the upper casing member without adding additional facilities or improving the size of mechanical rigidity in the connection part between the lower casing member and the upper casing member. The present invention also remarkably reduces manufacturing costs and risks of environmental contamination by preventing insulating oil from being leaked in a transformer accident and improves reliability of power supply.
