an electric configuration having interconnections that comprise the electrical substation, selected from the group consisting of circuit breakers, disconnectors, intensity measurement transformers, voltage measurement transformers, electric bars and combinations thereof;

an electric insulation technology selected from the group consisting of

outdoor insulation using air as dielectric insulator, and

elements encapsulated within armoured modules in an insulating environment selected from SF6 (sulphur hexafluoride) and other insulators; and

a physical layout of electric phases;

an electric layout implemented by means of single-phase armoured modules M, forming longitudinally-linked electrical squares, respective input/output positions L projecting from each of said electrical squares; each of the armoured modules M comprising a circuit breaker I, two intensity measurement transformers TI, two disconnectors S and two grounding disconnectors S′;

the electric insulation technology comprising independent and insulated chambers by means of said insulating environment, for elements selected from the circuit breaker I, the intensity measurement transformers TI, the disconnectors S and the grounding disconnectors S′; and

the physical layout of the electrical phases being implemented in a manner selected from: by position and segregated, enabling a connection of converging input/output positions L, regardless of its layout in case the input/output positions L are lines, avoiding crossing of lines and surrounding routes, also enabling a physical layout of the armoured modules M to be selected from ring, line and combination of ring and line.
