Carrying and switching system (1) for above ground electric power line voltage with a triangular arrangement of conductors (2, 3, 4) comprises a support system which is mounted on the top of the column (5) which consists of the lower arm (34) carrying the anchor chain insulator (7 ) the two outer of conductors (2, 4) and a central arm (35) carrying on the anchor chain insulator (8) the center conductor (3). Further includes a switching system arranged on the column (5) below the grid and comprising switching elements (11, 12, 13), which are using leakage wires (14, 15, 16) connected to the wires (2, 3, 4). Disclosure of solution consists of the fact that above the lower arm (34) is arranged horizontally isolated abutting console (36) for the birds which its upper contact surface is located at H => 300 mm above the phase conductors (2, 4), or of their anchor chain insulator (7), and at least leaky central conductors (15) connecting the country's center conductor (3) with a switching element (12) are isolated and / or adapted for auxiliary insulator (20), arranged transversely to the abutting console (36) and are stored in a protective insulating cover (21) at least in the area abutting console (36). |
