An aircraft comprises a fuselage, at least a first electrical generator and a second electrical generator, a set of electrical equipment items distributed in the fuselage and an electrical power distribution network comprising a switching system and a set of buses. The buses comprise at least a first bus and a second bus extending, at least partly, in a longitudinal direction of the fuselage and following segregated paths in the fuselage. In a normal mode of operation, the switching system links the first electrical generator to the first bus and the second electrical generator to the second bus. Each bus comprises connection points at different locations distributed along its length and each of the electrical equipment items is linked to a connection point of a bus via a local electrical power supply link.
