DEVICE TO REPLACE INSULATORS ON OVERHEAD POWER TRANSMISSION LINES Russian patent published in 2011 - IPC H02G1/00 

FIELD: electricity.

SUBSTANCE: device comprises detachable clamps (2, 3), arranged of brackets and a tightening mechanism. The clamp (2) has inserts in the form of a canted semi-tumbler of alternating cylindrical form with axial hole and flange with holes designed for fixation to brackets. The axial holes is arranged with radius R₁=(0.51÷1.6)d_p, where d_p is minimum diametre of the insulator (1) pestle, for which the device is designed. The clamp (3), similar to the clamp (2), is equipped with inserts arranged as canted semi-tumblers of cylindrical shape of identical diametre along their whole height, with a flange along side surface and a hole for fixation of the clamp (3) brackets. The hole is also arranged with the radius R₁=(0.51÷1.6)d_p. The flange is arranged at height determined based on the following ratio: h=(0.4÷0.85)H, where H is a pillar height. An insert from organosilicic rubber in the form of a cylindrical washer with flat surface at one side and circular ledges at the other side is installed on the base of the insert.

EFFECT: simplification and reduction of manufacturing and operation process cost.
