Because the gas-insulated transmission line(GIL) is very long so the design is generally divided into a plurality of inflatable units.Each line inflatable unit is composed of a plurality of manufacturing units and generally contains an telescopic joint.In order to ensure the line inflatable unit only to move along the axial direction and not move radially during the normal operation
the installation modes of each line inflatable unit should be one point fixed and other points can move freely.And how to properly design the position of fixed fulcrum and to calculate the intensity of support bracket is also discussed in this paper.
