A utility pole, commonly referred to as a transmission pole, telephone pole, telecommunication pole, power pole, hydro pole, telegraph pole, or telegraph post, is a column or post used to support overhead power lines and various other public utilities, such as electrical cable, fiber optic cable, and related equipment such as transformers and ...
Dead-end towers may use earth anchor cables to compensate for the asymmetric attachment of the conductors. They are often used when the power line must cross a large gap, such as a railway line, river, or valley. Dead-end towers may be constructed of the same materials as other structures of the line.
Strain insulator - A dead end or anchor pole or tower is used where a straight section of line ends, or angles off in another direction. These poles must withstand the lateral (horizontal) tension of the long straight section of wire. To support this lateral load, strain insulators are used.
The anchor must be adequate to resist the maximum tensile load of the guy wires; both the dead load of the tension of the wire and the maximum possible live load due to wind. Since the guy wire exerts its force at an angle, the anchor has both vertical and lateral (horizontal) forces on it.
Wire transposition on top of pole. A transposing scheme is a pattern by which the conductors of overhead power lines are transposed at transposing structures. To ensure balanced capacitance of a three-phase line, each of the three conductors must hang once at each position of the overhead line.
A three phase electric circuit terminated with a pothead Crossarms with two three phase electric circuits terminated with potheads. A pothead is a type of insulated electrical terminal used for transitioning between overhead line and underground high-voltage cable or for connecting overhead wiring to equipment like transformers.

A weatherhead on a residence in Mount Vernon, Washington, US. A weatherhead, also called a weathercap, service head, service entrance cap, or gooseneck (slang) is a weatherproof service drop entry point where overhead power or telephone wires enter a building, or where wires transition between overhead and underground cables.
