Two prototype electro-mechanical cables were evaluated electrically and mechanically to determine the suitability of the design and of the manufacturing process to the requirements of the Navys Remote Unmanned Work System, RUWS. Electrical measurements included characteristic impedance, attenuation, DC resistance, dielectric resistance, insulation resistance and corona onset and extinction voltages. Mechanical experiments measured torque balance, elongation, tensile strength and fatigue life under simulated operational conditions. The prototype cables included a coaxial conductor core surrounded by two contrahelical strength member layers which were constructed of KEVLAR-49, a high-strength, high modulus organic fiber material developed by du Pont. Its advantage, for the RUWS application, is the reduction of cable weight without sacrifice of cable strength. Modified author abstract
