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.

A joint-use bracket (JUB) for installing multiple communication lines in a joint-use section on a utility pole is disclosed. The JUB includes a curved plate having a generally rectangular shape elongated in a longitudinal direction and curved along a lateral direction. The curved plate is formed to have one or more attachment holes, one or more slots, and multiple threaded receiving holes. The JUB also has multiple hooks formed contiguous to the front surface of the curved plate, each hook having a threaded through hole, wherein multiple bolts are associated with the multiple hooks, respectively. Each hook is configured to hold a wire or a cable through a D-shaped opening that is formed by the hook and the bolt when the bolt is screwed in through the threaded through hole to have the end portion engaged with the threaded receiving hole.
