Description

Underground distribution line connection device for improved safety and usability The present invention relates to an underground power distribution line connection mechanism for wire connection that improves safety and usability. Generally, the undergrounding of overhead power lines in Korea began with the relocation of utility poles along main roads to back alleys and the use of low-voltage cables to supply power from pole-mounted transformers to nearby consumers, and this trend is continuously expanding. Construction methods for underground power distribution lines can be broadly classified into direct burial, conduit, power tunnel, and bridge addition methods. Among these, the power conduit type, also known as the culvert type or the conduit type, is constructed by joining concrete structures underground like pipes. Shelves are fixed vertically to the floor surface by being closely attached to the left and right side walls inside the concrete structure, and the entire structure, including the shelves, is called a tray. However, in this type of power conduit construction, since the shelves are simply fixed in layers on the inner side of the concrete structure and on both side walls, if water leakage occurs in the concrete structure, water seeps in along the shelves installed on both side walls, causing leakage or short circuits in the underground power distribution line. If this situation is continuously repeated, oxidation is accelerated, which shortens the lifespan of the underground power distribution line.
