A structure for installing an underground power cable of a substation is provided to previously prevent an electricity leakage or an electric short from generating by blocking a penetration of underground water. In a structure for installing an underground power cable(1) of a substation, the underground power cable(1) passes through the inside of a cable pipe(110). A pair of first flanges are formed on both ends of the cable pipe(110). A packing drum(120) is formed in a shape of a hollow cylinder. A second flange is coupled to the first flange of the cable pipe(110). A plurality of connection bolts is protruded upward from a top inside of a bending portion. A first through hole is formed on a central portion of a packing rubber ring(130) to pass the underground cable(1). The packing rubber ring(130) is inserted into the top inside spatial part of the packing drum(120). A finger compression plate(140) is formed in a cylindrical shape to be inserted into the top inside spatial part of the packing drum(120). And, a cover(150) is formed in a cylindrical shape opened at a bottom portion thereof and is fixed to ground concrete. |
