Power transmission systems with cooling mechanisms, and methods of operating the same, are described. A power transmission system can include multiple support tower assemblies. Each of the support tower assemblies includes a support tower. One or more of the support tower assemblies includes a termination (i.e., a connection point via which electrical current and/or coolant can enter the transmission line and/or exit the transmission line). The power transmission system also includes multiple conductor assemblies suspended above a surface of the earth. Each conductor assembly includes an electrical conductor and is positioned between, and mechanically supported by, a pair of the support towers. The power transmission system also includes a coolant supply system that delivers a coolant fluid, during operation of the power transmission system, to at least one of the terminations, for cooling of the conductor assemblies.

The subject matter of the present disclosure may be embodied in devices, such as flexible wiring, that include: an elongated flexible substrate; multiple electrically conductive traces arranged in an array on a first side of the elongated flexible substrate; and an electromagnetic shielding layer on a second side of the elongated flexible substrate, the second side being opposite the first side, in which the elongated flexible substrate includes a fold region between a first electronically conductive trace and a second electrically conductive trace such that the electromagnetic shielding layer provides electromagnetic shielding between the first electronically conductive trace and the second electrically conductive trace.

A conductor assembly for transmitting power includes a former that defines a shape, a superconductor material disposed around the former, and a thermally insulating jacket (TIJ) disposed around and spaced apart from the superconductor material. An outer surface of the superconductor material and an inner surface of the TIJ can define an annulus through which a coolant can flow. The conductor assembly can also include an external layer, disposed around an outside surface of the TIJ, to provide structural support to the conductor assembly. The conductor assembly can also include an electrical insulation layer disposed around the outside surface of the TIJ or around the superconductor material.
