An apparatus for connecting a high voltage cable of a substation is provided to offer power to consumers and reduce repair cost by supporting a connecting unit of the cable with a cable support and preventing the disconnection of the connecting unit. An apparatus for connecting a high voltage cable(1) of a substation includes a cable insertion guide hole(10), a water-leakage blocking ring(20), a connector(30), and a cable support(40). The cable insertion guide hole is installed to face a manhole and consists of a plurality of cylindrical cable pipes(11) which penetrate the side wall of the underground manhole and has the high voltage cable inside, an outer wall waterproof plate(12) which is integrally formed at one side of the cable pipe and has the inner surface supported by the outer surface of the manhole, an inner wall waterproof plate(13) which is integrally formed at the other side of the cable path and has the inner surface supported by the inner surface of the manhole, and a cable guide pipe(14) which is protruded to be connected with the cable pipe and guides the high voltage cable. The water-leakage blocking ring is coupled by a plurality of bolts at the outer surface of the inner wall waterproof plate, and seals the gap between the inner wall waterproof plate and the high voltage cable. The connector is pipe-shaped with a diameter to become larger toward one end and both open sides, and is inserted into the end which faces the high voltage cable, and consists of a first connecting piece(31) and a second connecting piece(32) which seal a connecting unit of the high voltage cable by being charged with a water stopping agent through injection holes. The cable support has a curved cable installment groove at the upper surface and a bottom unit(42) to support the cable support inside the manhole, and supports the high voltage through the cable installment groove. |
