1. A modular system applied to transformers, comprising:
a structure comprising a plurality of modules having different dimensions, each module comprising piping that forms a closed shape that extends around a perimeter of a transformer tank, each module being coupled to the transformer tank by means of flanged connections, wherein the piping of larger dimensioned modules and of smaller dimensioned modules are coupled between each other by means of flanged connections, wedge, blind flange and by fitting, and the piping of the larger dimensioned modules comprise in their interior outlines and channels and in their exterior rails and the larger dimensioned modules support ventilation and cooling systems in their horizontal piping and the smaller dimensioned modules, which are comprised of vertical piping and upper and lower horizontal piping, support auxiliary circuit boxes, monitoring systems and valve piping.
