A twenty-two gauge AWG flexible power-wire system was fabricated using seven strands of 0.010-inch-diameter rhodium wire, bulk aluminum oxide and silicon dioxide insulation, knitted Inconel wire sheathing, and Monel end terminations. This wire system maintained its electrical integrity through a variety of environmental tests, including vibration, mechanical shock, acceleration, humidity, vacuum, and nuclear radiation. The wires were operated under various temperature-pressure conditions from room tepmerature to 2000 F and sea level to 500 miles. Design parameters were determined, including maximum rated current, dielectric strength, insulation resistance, resistivity, corona onset voltage, transmission line characteristics, and flexibility. These insulated conductor cables should find application as high temperature power and control conductors in nuclear reactors and direct energy conversion devices as power and control conductors in the leading edges and other hot regions of supersonic and suborbital vehicles. The conductors may also be used with suitable further protection for antenna connectors leading through the nose cone of a reentry vehicle to a hypersonic antenna permitting control and telemetry during reentry. An industrial application consists of insulated high temperature 1200 - 1500 C furnace windings.
