    Abstract: A cooling system for a subterranean power line may include a cooling tube configured to house a fluid. Heat generated by the subterranean power line may be radiated and/or conducted to the cooling tube and absorbed by the fluid within the cooling tube. As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.

    Abstract: A support system for supporting one or more transmission lines and for mitigating sagging or swinging of the transmission lines may comprise support lines coupled to the transmission lines by adjustable risers. The adjustable risers may be dynamically adjustable in length to compensate for the sagging or swinging of the transmission lines. Various embodiments of the adjustable risers, support lines, and support system are contemplated. These embodiments may include adjustment mechanisms, sensors, shock absorbers, positioning mechanisms, zero gap connections, guy wires, lateral members, and various different arrangements of the elements.
