ASSEMBLY KIT FOR INTERMEDIATE OVERHEAD TRANSMISSION LINE POLE Russian patent published in 2014 - IPC E04H12/12 

FIELD: electricity.

SUBSTANCE: assembly kit includes reinforced concrete rack, isolated wire fixation elements 2, support element 3 for attachment of elements 2, clamp 5 for connection of support element 3 to rack armature for earthing. Elements 2 are made in the form of three electric isolation cross-bars, each consisting of two isolators 7 with lugs 8, 9 at each end, pad 10 and wire fixation element 11, so that each isolator 7 has a joint connection at the end 8 to pad 10 which is also connected to element 11 by a joint. Support element 3 is made in the form of long extension for vertical bracket fixation in extended position on top 4 with four lugs 14-17 at one side and two lugs 18, 19 at the opposite side. Lugs 14-19 are positioned in sequence along the length of long extension (3) and allow for joint connection of isolators on them by lugs 9 so that isolator pairs 7 are positioned in geometrical longitudinal axes at an angle to each other. Long extension includes two steel angles 20 bent at top 21 and welded together at the top with the help of strap 22 so that one of shelves 23 is positioned in the same plane with shelf 23 of the other angle and towards these shelves to form side walls of long extension (3) by other shelves 24, where lugs 17-19 are attached; long strap 26 welded to shelves 23 at the end of long extension (3) with protruding ends 27 at side walls where holes for bracket 12 ends; set of reinforcing plates 30 with at least one plate welded at each level of lugs 14-19, so that each reinforcing plate 30 is attached by its opposite sides to internal surfaces of both steel angles 20.

EFFECT: extended range of equipment for erection of overhead transmission line poles by intermediate pole erection kit with simple and compact design of supporting element for fixation of isolated wire bearing elements, simplifying pole transportation to the site and erection.
