摘要： 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.
