Description

Underground distribution line support device with wire protection The present invention relates to a wire protection type underground power distribution line support device capable of protecting wires. 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. Underground power distribution line construction methods 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 side walls inside the concrete structure, if water leakage occurs in the concrete structure, seepage water flows in along the shelves installed on the side walls, causing leakage or short circuits in the underground power distribution lines. If this situation is continuously repeated, oxidation is accelerated, which shortens the lifespan of the underground power distribution lines. In particular, if objects fall from the ceiling of a power conduit onto underground power lines, it directly leads to damage to the lines, which incurs time and costs because the lines must be replaced.
