Abstract: In a distributor, a plurality of switches are connected in series with one another on main distribution lines emerging from a receiver switching apparatus, thus forming a trunk. A branch line extends from a junction between each pair of adjoining switches and leads to each load via another switch and a transformer, wherein each pair of switches on the trunk is formed as a single branch unit, and the switch and transformer are united as a power package. In each power package, a supply bushing and a load bushing are placed on the top of a transformer, and shielded with closed housings. A switch is placed in the closed housing for the supply bushing, and a distribution board is placed in the closed housing for the transformer. This configuration enables the disconnection of any branch distribution lines from the main distribution lines and diminishes the installation space.
