Description

Underground power distribution line connection device capable of safety inspection {Connector Equipment for Underground Line} The present invention relates to an underground power distribution line connection device capable of safety inspection. Generally, electricity produced at power plants is distributed to each consumer through overhead distribution lines. Meanwhile, recently, underground power distribution using power conduits is being widely used rather than overhead power distribution for urban aesthetics and safety. As shown in Fig. 1, the underground power distribution method involves installing a tray (2) inside a power conduit (1) to arrange the underground power distribution line (3). However, conventionally, when an underground power line (3) is connected to a tray (2), if a leakage current occurs from the underground power line (3), it is not possible to inspect it, making it difficult to respond safely to the leakage current. In addition, conventionally, when placing an underground power line (3) in a tray (2), it was difficult to safely move the underground power line (3) to the tray (2) and conveniently place the underground power line (3) on the upper surface of the tray (2).
