  • Patent number: 4131759
    Abstract: A multiple caged armored electromechanical cable is provided which is characterized in being torque balanced and strength tapered throughout its entire length. The selective strength tapering of the cable permits the orientation of the cable such that the strongest portion thereof will support the entire cable and the weakest portion thereof will support only itself and whatever instrumentation is desirable. A slip sleeve mechanism is provided for retaining portions of the strength tapered elements of the cable to prevent inadvertant electrical shorting as well as providing for a relative slippage of the tapered strength elements with respect to select other elements of the cable.
