A stop joint for a pair of electric cables having fluid under pressure therein in which the fluid impermeable pipe or shield around the cable, which is spaced at its end from the bared conductor end to expose the cable insulation, is connected to the connector for interconnecting the cable ends by a multi-part stop tube having an intermediate portion of insulating material and a pair of end portions bonded to respective ends of the intermediate portion, the end portions being made of an insulating material rendered conductive by the addition of conductive material or of insulating material having a conductive layer thereon for forming electrodes for electrical stress distribution purposes. The electrodes have substantially the same coefficient of expansion as the material of the intermediate tube portion to prevent separation of the end portions from the intermediate portion with temperature changes.

Stop joint assembly for pressurized laminar dielectric cable

In a pipe type electric cable installation in which portions of the cable cores extend into a joint casing where the conductors of the cores are conductively joined, the portions of the cores within the casing are enclosed by tubes which are longitudinally curved, preferably, S-shaped, to restrict axial movement of the cores with varying load conditions, one end of each tube being anchored, at least with respect to longitudinal movement, to the casing.
