Busbar system of electric high-voltage switchgear

In a busbar system, the combination of:

• a support and an insulator carried by said support;
• a busbar attached to said insulator in spaced relation to said support, said busbar comprising a pair of elongate, parallel rods, each having an inner face and an outer face, said outer faces being semicircular and said inner faces being disposed in spaced relation to each other so that said outer faces define a generally cylindrical envelope, said insulator having a portion disposed between said inner faces and said inner faces of the bars each having a longitudinally extending T-slot;
• and
• means for attaching said busbar to said insulator, said means comprising a pair of bolts having their heads received in the respective T-slots of said bars whereby the attachment may be made at a selected longitudinal position along said busbar.
