Abstract

The present invention relates to a joint box for an ultra-high voltage direct current power cable, and an ultra-high voltage direct current power cable system comprising the same. Specifically, the present invention relates to a joint box for an ultra-high voltage direct current power cable which can effectively prevent dielectric breakdown of the joint box of the cable due to local field concentration by alleviating an electric field at a portion on which the electric field structurally concentrates, and an ultra-high voltage direct current power cable system comprising the same.
