Apparatus for jointing CV cables

A power cable joint structure in which a sheath isolation is provided in a cable shielding layer in, for instance, each phase of a three-phase circuit. A reinforcing insulation is covered on the connected cable conductors and a shielding layer is covered on the outer periphery of the above-mentioned joint itself. The shielding layer has a pair of mutually opposite layers with a gap therebetween which provides a sheath isolation. A thick sheet-like insulator 12 with a plurality of spherical electrodes distributed therein is contained in the sheath isolation.

Power cable joint structure having sheath isolation member containing

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.
