A superconducting cable includes a cryogenic fluid, a superconducting conductor, and a cryostat. A layer impervious to the cryogenic fluid is provided between the superconducting conductor and the cryogenic fluid. The superconducting conductor operates in a space substantially free from fluids liquefying at a temperature greater than or equal to an operative temperature of the superconducting cable. A method for protecting a superconducting cable from formation of balloons includes isolating the superconducting conductor from the cryogenic fluid using a layer impervious to the cryogenic fluid and operating the superconducting conductor in a space substantially free from fluids liquefying at a temperature greater than or equal to an operative temperature of the superconducting cable. A current transmission/distribution network including at least one of the superconducting cables is also disclosed.
