Abstract
A system () for transporting electric energy in superconductivity conditions includes a superconducting cable () including superconducting material, and a cryogenic plant () for cooling said superconducting cable () below the critical temperature of the material, comprising: a) a circuit () for circulating a first refrigerating fluid having a first predetermined temperature lower than the critical temperature of the superconducting material, from and to the superconducting cable (); b) a refrigerating circuit () for cooling a second refrigerating fluid to a second predetermined temperature lower than the temperature of the first refrigerating fluid; c) a heat exchange unit () for effecting a heat exchange between the first and second refrigerating fluids, which is characterized in that the heat exchange unit () is provided with a storage unit () of a third refrigerating fluid having a third predetermined temperature lower than the temperature of the first refrigerating fluid and being in heat exchange relationship with the first and second fluids.
