A tower testing station is a special plant for testing various design for towers for transmission lines and similar uses. A tower testing station consists of two steel stands and one or more foundations, on which a sample of the tower can be built.
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.
Partially guyed towers are typically used when a very high tower for FM and TV transmission is required, while also carrying antennas for directional radio services at a much lower height. In such cases the antennas for directional radio services are mounted on the top of the free-standing part of the tower, while the guyed mast on its top ...
In the case of the cross-rope suspension tower, the tower legs are spread apart on two different foundations. [35] In addition, the crossbar is replaced by a series of suspension cables with three vertical insulator strings to support the three bundles, which allows this design to consume only 6.3 tonnes of steel per kilometre of line.

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.
