Abstract: A typical embodiment of the invention is directed to a "Horizontal Vee" power transmission line conductor installation system. Typically, a connector protrudes from the insulator coupling. A cable clamp is releasably attached to the connector. An auxiliary cable seized in the clamp also is attached through cable grips to the line conductor. A come along transfers load from the line conductor to the cable to enable the slackened portion of the line conductor to be clipped by a suspension clamp and permanently joined to the connector. The auxiliary cable is released from the line conductor and removed from the connector in order to transfer the line conductor load back to the line conductor. This technique avoids the need for cranes, jib poles and other erection equipment and also avoids imposing excessive forces on the electrical insulators during installation.

Abstract: A shear bolt assembly for a load limiting line support for a post insulator comprising a bolt having a first portion engaged with a saddle of the line support and a collar engaged by a line clamp. The collar is in abutting relation with the bolt and the collar and bolt have aligned axial bores in which a shear pin is secured. The shear pin can be secured in the collar and bolt by an adhesive layer and the shear pin can be brought into electrical contact with the bolt by providing a knurled section at one end which establishes interference fit and mechanical contact between the shear pin and the bolt.
