The present invention relates to a power transmission and distribution cable array structure of a common duct. The purpose of the present invention is to easily construct and maintain power transmission and distribution cables and array structures, wire a number of power transmission and distribution cables, and obtain a space for workers capable of passing in a comfortable position by installing a plurality of array structures of a common duct. The power transmission and distribution cable array structure of the common duct by the present invention comprises plate-shaped trays (10) which are installed in multiple stages in the wiring direction of the cable at both inner walls of the common duct and on which the cable is formed on the upper surface thereof; and a tray support (20) which is inclined at the bottom of the tray and fixed to the inner wall of the common duct by an anchor. The tray includes a plate-shaped tray body (30) which is equipped with a mounting groove of the cable; a guide block (32) which is installed at the outside of the upper surface of the tray body to be rotated, prevents the separation of the cable installed on the tray body, and guides the cable to the mounting groove of the tray body; and an auxiliary tray (40) which stores the cable by pushing the cable to the tray body or supports the cable formed on the tray body by being installed at a storage part formed inside the tray body for being drawn and rotated to the outside. |
