Abstract: The present invention provides a superconducting cable system suitable for use over long distances and adapted to achieve improved heat absorption through the use of the latent heat of vaporisation of a liquid cryogen, the system including a cryogen supply duct, a superconductor extending longitudinally of the supply duct, a vapour return duct and an evaporation enabling medium disposed between the supply duct and the vapour return duct.

Abstract: The present invention provides a superconducting cable system designed to facilitate long distance superconducting, the cable system including at least one inner cryostat containing a supply of cryogenic fluid and at least one superconductor extending longitudinally of the inner cryostat and in thermal communication with the cryogenic fluid, the inner cryostat comprising a liquid crystal polymer.
