FIELD: electricity.SUBSTANCE: assembly kit comprises a rack 1 having a carrying plate with openings at the top, extension piece 4, which is made as a pipe section of rectangular cross-section with the base made as a plate fixed at one butt ends with openings, the first beam 7 made as a section of flat-topped profile of normal cross-section with openings in its middle part placed in regard to the profile length, near its middle part 9, at that at ends 10 of the profile there are rigidly fixed parts for attachment of suspended insulators 12; the second beam 13 made as a pipe section of rectangular cross-section, at which one of the ends there is a rigidly fixed part 15 for attachment of a suspended insulator 16. The first beam 7 is made so that it may be placed at the top 3 of rack 1 with placement of the carrying plate of rack 1 in its cavity while extension piece 4 may be placed above the first beam 7 with its base as continuation of rack 1. Openings in the carrying plate of rack 1, in the first beam 7 and at the base of extension piece 4 are made so that they may be matched and tightened by threaded fasteners 18. The second beam 13 is made so that it may be fixed at extension piece 4 from the side of its second butt end orthogonally to longitudinal direction of rack 1 in the same plane with the first beam 7.EFFECT: widening range of equipment in the form of assembly kit for construction of poles intended for overhead transmission lines, increasing carrying capacity and reliability of poles.8 cl, 11 dwg |
