FIELD: power industry.

SUBSTANCE: impeller of electromechanical plant has large overall dimensions; its diameter can be 20 and more metres; and so it cannot be transported as assembled to place of destination. Impeller consists of several sectors with length of chord, which does not exceed 4.6 metres gross; the above sectors are transported to the site and then attached to each other and to the hub with attachment assemblies. Each sector consists of part of radial-annular framework, part of external mounting spar, parts of lower and upper covering; at that, each sector is restricted with reinforced ribs which are adjacent to reinforced ribs of other adjacent sectors which are overlapped, and parts of external mounting spar are attached by butt welding.
