Zusammenfassung:The present invention relates to a joint box for an ultra-high-voltage direct-current (DC) power cable and an ultra-high-voltage DC power cable system including the same. Specifically, the present invention relates to a joint box, for an ultra-high-voltage DC power cable, which is capable of alleviating an electric field in a region in which an electric field concentration occurs structurally to effectively prevent dielectric breakdown of the joint box due to a local electric-field concentration, and an ultra-high-voltage DC power cable system including the same.
