<p>A main distribution station for the distribution of electric power includes a high voltage part (5) a medium voltage part (6) and at least one transformer (7, 8) connected between the parts. Each on part comprises multiphase feed sectors mounted so that they may be arranged together with corresponding additional feed sectors each forming a complete feed ring, wherein the high voltage feed ring is positioned axially above the medium voltage feed ring while the transformers are installed at the side of these rings. Apart from the transformers the entire main distribution station may be installed within a two storeyed tower in which the medium voltage part (6) is installed within the lower storey while the high voltage part (5) is located in the upper storey. A substation for the distribution of electric energy may include only a medium voltage part supplied by means of a cable, rather than by a transformer. <IMAGE></p> |
