Abstract :
Twenty-two gage and 12-gage power conductors were developed using rhodium power wires, magnesium oxide insulation, platinum sheathing, and alumina end-seals. The conductor systems maintained their electrical integrity through a variety of environmental tests, including vibration, mechanical shock, acceleration, humidity, vacuum, and nuclear radiation. The wires were operated successfully at 2000??F. Rated current was determined and assigned as 10 amperes for 22-gage and 60 amperes for 12-gage conductors. The conductors passed the final cyclic test of carrying rated current at room temperature for 2 hours, at high vacuum for 25 hours, and at a reduced pressure at 2000??F for 3 hours.
