Abstract In a gas-insulated isolated-phase bus bar installation suitable for transmitting electric power at a voltage of at least 22 kv. and a current of at least 1,000 A. comprising a tubular loadcarrying conductor mounted coaxially within a tubular outer enclosure, a length of load-carrying conductor is mounted by a plurality of supports each comprising a control hub which adheres to the surface of the said tubular conductor, to a metal sleeve fitting into the said tubular conductor, or to a metal tube acting as a joint between lengths of the said tubular conductor. The shape of each spacer is such that the cross section of the hub in any plane at right angles to the conductor axis is substantially circular and its section in any plane passing through the conductor axis is substantially elliptical at each end of the hub, with the major axis of the ellipse lying on the inner surface of the hub and the minor axis of the ellipse lying on a radius of the conductor cross section and extending to substantially the maximum thickness of the end part of the hub. The ellipse may be a circle.
