Abstract
A tube enclosed pressure gas insulated electrical cable has at least one conductor supported within a tubular enclosure by means of insulators, the conductor being sectionalized longitudinally and provided with expansion joints between the ends of adjacent sections to compensate for thermal expansion of the conductor. To protect the expansion joint and prevent it from being compressed and possibly collapsing under the inherent weight of the internal conductor structure when the cable is laid down a steep slope, a protective device is provided, this being constituted by a compression spring interposed between the ends of adjacent sections at the expansion joint for counteracting the weight of the conductor on the joint.
