  • Sodium filled flexible transmission cable
    Patent number: 4056679
    Abstract: A corrugated flexible thin copper tube filled with sodium has a resilient flexible core along the axis thereof so arranged that it will contract and expand to take up the force of thermal expansion and contraction of the sodium. Since the coefficients of expansion of the sodium and copper are different, the absorption of this differential in force by the core prevents rupture of the copper tube and the formation of voids and hot spots within the copper tube.
