Abstract:
This invention provides a low temperature electrical transmission system which is defined by an elongated conduit having at least one electrical conductor internally positioned within said conduit, an outer jacket surrounding said elongated conduit and a circulating cryogenic dielectric cooling liquid located between the electrical conductor and the elongated conduit for simultaneously cooling and electrically insulating the conductor from the conduit and from the outer jacket. Thermal insulation is positioned between the outer jacket and conduit to prevent heat inleakage.
Abstract:
Disclosed are fluid-cooled, high-current capacity electrical conductors manufactured by spirally rolling or winding porous metal sheet into a desired shape.
