Superconducting Power Cable : HTS system operating at temperatures just below the boiling point of liquid nitrogen reduces resistance to the flow of electric current

Power CableAmerican Electric has launched a test of high temperature superconducting power cables operating at extremely low temperatures to reduce resistance to the flow of electric current. HTS cables can deliver up to five times more electricity than traditional conventional copper or aluminum cables. With their higher capacity, superconducting cables have the potential to increase the supply of electricity to an area using the existing underground cable footprint. Additionally, because HTS cables can carry more current at a lower voltage over longer distances, large power transformers could be located farther from urban centers and densely populated areas freeing up valuable real estate for development or green space. Although called high-temperature, this HTS system operates at temperatures just below the boiling point of liquid nitrogen (-321 degrees Fahrenheit).
