1. An intermediate connection structure of a power cable for connecting a pair of power cables, wherein the power cable comprises a conductor, an inner semiconducting layer outside the conductor, a cable insulating layer outside the inner semiconducting layer, an outer semiconducting layer outside the cable insulating layer, and a metal sheath outside the outer semiconducting layer, and
the intermediate connection structure comprises a conductor connection part to which a pair of conductors are connected, an inner semiconducting restoration layer outside the exposed conductor of the power cable and the conductor connection part, an insulating restoration layer for covering at least portions of the inner semiconducting restoration layer and the cable insulating layer, an outer semiconducting restoration layer outside the insulating restoration layer, and a metal sheath restoration layer outside the outer semiconducting restoration layer,
wherein an end of the metal sheath of the power cable and an end of the metal sheath restoration layers are spaced a predetermined distance from each other, a metal taping layer is provided below a boundary area between the end of the metal sheath of the power cable and the end of the metal sheath restoration layer, and the boundary area is finished with a soldered part.
