MONOBLOCK FOR WIRE AND/OR OPTICAL CABLE ATTACHMENT TO POWER LINE TOWER BODY Russian patent published in 2009 - IPC H02G7/20 H01B17/02 

FIELD: electricity.

SUBSTANCE: invention is attributed to the field of electrical equipment. Monoblock body has carrying element 1 in the form of equilateral trapezium along lateral faces 2 and smaller base 3 of which bent bearing part repeating the shape of lateral faces 2 and smaller base 3 of trapezoidal carrying element 1 is welded at right angle. In the first version of invention inside the angle formed by coupled carrying element 1 and bearing part 4 and at right angle to their surfaces, two steel strips 6 and 7 are welded to envelope tower body end portion by their facing surfaces. Ring-shaped part (9, 10) is fixed at ends of strips 6 and 7. In the second version of invention angle seat is welded by its leg outer surface to one of the sides of carrying element outer surface. Angle seat projects in opposite direction to bent bearing part location. In the third version of invention two angle seats are welded by their leg ends at sides of carrying element to its outer surface. Angle seats project in opposite direction to bent bearing part location. Each insulator comprises bearing part with element for insulator attachment, fiber-glass plastic rod attached by on its end to bearing part, head that is fixed on the second end of rod, and insulating body created of fiber-glass plastic around rod between bearing part and head with radial ribs made of silicon rubber.

EFFECT: structure weight reduction.
