ABSTRACT:
An insulated electric conductor employed in a tubular drill string to transmit electric energy between subsurface and surface locations is arranged within the drill string in a convoluted configuration to provide an excess length of conductor. The convoluted conductor is prevented from entangling during drilling by rotation limiting assemblies mounted in the drill string over a selected interval.
