Apparatus for changing the direction of a three-phase pipe-type gas-pressurized electrical cable

In a three-phase pipe-type gas-pressurized electrical cable constituted principally by rigid straight pipe lengths connected in series and wherein the axes of the three phase conductors supported within the pipe when viewed in cross-section form an equilateral triangle, the improvement wherein means are provided for changing the direction of the cable, said direction-changing means comprising a spherical elbow interposed between two straight pipe lengths, said elbow including a pair of branch pipe stubs connected to the ends of the adjoining straight pipe lengths and three curved conductor members supported in spaced relation within said elbow, one of said curved conductor members and which has the largest radius of curvature being located in a plane formed by the respective axes of said two branch pipe stubs which intersect at the center of said elbow and the other two curved conductor members having a smaller radius of curvature being located at equal distances on each side of said plane, and three intermedite conductor sections connecting and adapting the respective positions of the ends of the three conductors supported within the adjoining pipe lengths to their correlated conductor members within said elbow.
