Transmission tower in Toronto, ON Single-circuit three-phase transmission line Transmission towers on a hill field. Three-phase electric power systems are used for high voltage (66- or 69-kV and above) and extra-high voltage (110- or 115-kV and above; most often 138- or 230-kV and above in contemporary systems) AC transmission lines. In some ...
Termination tower (overhead line to underground cable) Future termination tower of a 110 kV-line while joins are installed. A special kind of a dead-end tower is a termination pylon, also called a terminal tower. It is used when the overhead power line terminates, and is connected to substation equipment, or transitions to underground cable.
In electrical power transmission, a transposition tower is a transmission tower that changes the relative physical positions of the conductors of a transmission line in a Polyphase system. A transposition tower allows these sections to be connected together, while maintaining adequate clearance for the conductors.
In an electric power transmission line, a suspension tower is where the conductors are simply suspended from the tower, the mechanical tension being the same on each side. [ 1 ] In this case, the tower is supposed to carry a downward force, and a lateral force , but not a longitudinal force.
