Joint for ultra high voltage cable and ultra high voltage cable joint system comprising the same

摘要

The present invention relates to an intermediate junction box for an ultra-high voltage DC power cable and an ultra-high voltage DC power cable connection system including the same. Specifically, the present invention provides an intermediate junction box for an ultra-high voltage DC power cable, which can effectively prevent insulation breakdown of the intermediate junction box of the cable due to local electric field concentration by mitigating the electric field in the part where the electric field is structurally concentrated, and the intermediate junction box comprising the same It relates to an ultra-high voltage DC power cable connection system.
