Sodium Conductor
An electrical conductor formed by injecting molten sodium under inert gas atmosphere into a tube of sheathing material. The molten sodium solidifies without external cooling and the conductor can then be put through a die to ensure continuous contact between sheathing material and sodium. A central high tensile core can be introduced into the tube and held in position in the center of the tube while the liquid sodium is introduced. The sodium should not be exposed to air because of high reactivity.
