Tower Division

An electrical tower or electrical support (sometimes called turret) is a high - rise structure typically constructed in lattice of steel, whose main function is to support the electrical conductors flight of the transmission lines of electrical energy. They are used both in high and low voltage electrical distribution and in DC systems such as railway traction. They can have a great variety of shapes and sizes depending on the use and voltage of the energy transported. The normal ranges of height range from 15 m to 55 m, although sometimes it can exceed 300 m. 1 In addition to steel, other materials such as concrete and wood can be used.

Types of towers Division

According to their function they can be classified as:

· Suspension tower: They only serve to support the drivers; they are employed in straight alignments.

· Mooring towers: They are used to provide mooring points when suspension cannot be used by hanging (Recommended up to 30 KV and never at an angle)

· Anchor Towers: They are used to provide firm points in the line, which limit and prevent the total destruction of the line when for any reason a conductor or support is broken.

· Angle Towers: Employees to support the conductors in the vertices or angles that form the line in their layout.

· Towers of end of line: They support the tensions produced by the line; they are the strongest anchor point.

· Special towers: with different functions to the previous ones; they can be used for crossing over railways, waterways, telecommunication lines or a fork.

Design

In its design, the following considerations, among others, must be taken into account:

· Number of drivers to be fastened

· Mechanical tension of the conductors

· Affectation of the wind , both in conductors and in the structure of the tower

· Electrical voltage (high voltage) of the conductors
