The method of installation, consisting in location of the sector by the shell surface on a fixed support therewith the shells of individual sectors approximate shell section as a whole, is offered. Mathematical expressions of deviation profile of the sector with the real sector size and distances, which define a position of the supports, are received. The factors affecting geometric accuracy of the shell section and the impact of these factors on the accuracy are examined. Problem of determination of the maximum deviation of the profile of the sector, depending on the tolerance of the sector size and distance, establishing the position of the supports, is set. The dependences of the maximum values of the deviation of the sector profile on the of the tolerance levels are gotten. It is shown that the proposed scheme can be installed to provide higher accuracy of the shell section, than that which has a separate sector.
