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.
