Thermoelastic analysis of a superconducting cable
Abstract
The thermoelastic response of a superconducting power transmission cable when it is chilled from ambient to operating temperature is described. The cable consists of coaxial stranded conductors separated with a cylindrical dielectric. Cable and reactions and internal stresses are determined. Sample results for a hypothetical cable indicate that cable end reactions and peak stresses in the strands are sensitive to the initial helix angles and initial helix radii of the conductor strands.
