Joint For Ultra High Voltage Cable And Ultra High Voltage Cable System Having The Same

摘要

The present invention relates to an intermediate connection box for an ultra high voltage DC power cable and an ultra high voltage DC power cable system including the same. More particularly, the present invention relates to an intermediate connection box for an ultra high voltage DC power cable, capable of effectively preventing the dielectric breakdown of a cable due to a local electric field concentration by alleviating an electric field in a part where an electric field is structurally concentrated, and an ultra high voltage DC power cable system including the same. The intermediate connection box includes a first electrode, a pair of second electrodes, and a joint sleeve.
