DEVICE TO ANCHOR AND INTERMEDIATE FASTENING OF OVERHEAD POWER LINE INDEPENDENT ISOLATED WIRES Russian patent published in 2010 - IPC H02G7/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly to overhead power line isolated wire fastening. Proposed device comprises casing (1), base (2) and one single-finger clevis (3) with hole to fasten anchor or support clamp. Casing (1) represents equilateral triangle with sides (5, 6) and base-plate (7) with slots (10 ,11) that have holes. Width 1 of every slot (10, 11) exceeds size S between faces of fastening bolt head, while distance A between extreme holes of plate 7 is determined from relationship A=(4.0 to 5.0)·d_bolt, where d_bolt is the fastening bolt diametre. Note that width I of slots (10,11) is I=S+(1.0 to 1.3) mm, where S is the distance between bolt hexagonal head faces. Note that distance L between casing lateral sides is L=(0.55 to 0.72)·A, casing height H is H=(1.0 to 1.2)·L, and casing lateral sides are made along radius R with its center located on the plane of plate 7 and calculated from relationship covered by this invention.

EFFECT: higher reliability, ease of mounting.
