Abstract
A direction-changing arrangement for 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 a triangle. The desired change in direction is accomplished by interposing a spherical elbow pipe between two straight pipe lengths which includes a pair of branch pipe stubs connected to the ends of the adjoining straight pipe lengths, and three curved conductor members supported within the elbow and arranged symmetrically to the plane formed by the respective axes of the two branch pipe stubs which intersect at the center of the elbow. Three intermediate conductor sections are provided and these serve to interconnect the ends of the three inner conductors within the adjoining straight pipe lengths with the ends of the three curved conductor members within the elbow.
