Abstract
In the joint structure for a power cable, a cable insulator covers a cable conductor. A reinforcement insulator is mounted on the said cable insulator. In the said reinforcement insulator there are disposed by dispersion a plurality of electrode spheres. The voltage applied in between the said cable conductor and a cable shielding layer covering the said cable insulator is borne by the electrostatic capacities occurring among the said electrode spheres.
Claims3
