ABSTRACT:
A gas insulated transmission line has an inner conductor supported by insulators including a fixed insulator and a movable insulator with each having recesses in their outer portion having recessed metallic inserts therein of like configuration. The fixed insulator has disposed within the insert a base of an interconnection strap that extends along the sheath and is welded thereto. An insulating standoff button is further provided on the exterior of the base of the interconnection strap and presses against the outer sheath. An insert of the movable insulator contains a roller assembly. Preferably the roller assembly includes a substantially cylindrical roller of a semi-rigid insulating material that has edges bearing against the outer sheath and conforming to the configuration of the outer sheath by reason of deformation under load.
