The present disclosure relates to a power cable and an intermediate connection structure, for connection thereof, which is capable of preventing the concentration of stress on a soldered part, which is configured to join a metal sheath of the power cable and a metal sheath restoration layer of the intermediate connection structure while ensuring airtight or watertight sealing therebetween, preventing deformation of or damage to the soldered part due to stress applied thereto, and minimizing thermal history in the power cable during the formation of the soldered part.

Intermediate connection structure of power cable

Provided is an intermediate connection system for an ultra-high-voltage direct-current (DC) power cable. Specifically, the present invention relates to an intermediate connection system, for an ultra-high-voltage DC power cable, which is capable of simultaneously preventing or minimizing electric field distortion, a decrease of DC dielectric strength, and a decrease of impulse breakdown strength due to the accumulation of space charges in an insulating layer of a cable and an insulating material of an intermediate connection part.
