ABSTRACT:
Apparatus for selectively connecting and disconnecting two sets (1, 2) of three-phase busbars via isolating switch means, said sets of busbars being covered by metal cladding (31, 32), and extending in two different directions in a common plane (40) such that the center-lines of the two sets intersect, wherein the point of intersection is located within a metal sphere (41) having sleeve joints (41, 42) to which the cladding (31, 32) of the busbars is fixed, with the axes of the sleeve joints lying in said common plane (40) and wherein where they pass through the sphere, the busbars of one of the sets occupy a first plane parallel to said common plane and wherein the busbars of the other set occupy a second plane parallel to said common plane and on the other side thereof relative to said first plane, said isolating switch means being provided with contact rods (51) to connect corresponding bars of different sets together, said contact rods (51) lying in a plane which is perpendicular to said first and second planes and which is inclined relative to both of said different directions in which said sets of busbars extend.
