Product Description

Transmission Tower Types

 

 

In the last article we discussed about the transmission line main accessories. Now we will discuss about transmission tower or pylon types.  The transmission tower is an important accessory and the performance of the transmission line depends very much on the design of the transmission tower. The electric transmission towers or pylons can be classified several ways. Here we will try to classify it broadly. The most obvious and visible tower types are

• Lattice structure
• Tubular pole structure

Varieties of tower types are used in practice. Traditionally self supporting lattice structures are used for electricity transmission line towers (see Fig-A). You will mostly find the use of self supporting type lattice structures for transmission lines in most of the power companies . The lattice structures can be erected easily in very inaccessible locations as the tower members can be easily transported. Lattice structures are light and cost effective. The main disadvantage of lattice structure is that it requires more ROW (Right Of Way). Right Of Way is the stretch of land acquired along the route length of line keeping the towers in the middle of ROW width. See Fig-D where the width of ROW is shown by double headed arrow. The ROW width is as per the standard set by Local authority or government agency. Clearly ROW is more for higher voltage line.
In the sketch of a single circuit lattice tower (Fig-A), two numbers of ground conductors are used. Theta is the shield angle. For reliably protecting the conductors from lightening this angle θ should be less than 30 degrees. In the Fig-A the phase conductors used are bundled type (twin conductor).
