Electrical energy is today ‘s most used type of energy without doubt. Demand for electrical energy, which began to be used for lightning purposes, grew rapidly over the next years. This situation has also made the need for energy transportation mandatory and energy transmission lines have been used for this purpose.

Population growth and technological developments (electric transportation, developments in automation systems etc.) have made it obligatory for the electrical energy produced to meet the demand above its own capacity.

To satisfy the growing need of electrical energy, establishment of new production facilities and generalization of transmission lines have become a necessity. Thus electrical energy transmission systems improved and energy production, transmission and distribution became a need.

If it is necessary to define the meaning of the electric transmission line. It is the system that allows the electrical energy acquired from Dams, Solar Energy Systems and Wind Energy Systems to reach consumers via Energy Transmission Lines through Substations.

There are Substation centres nears the electricity production facilites and electric consuption areas.

With these stations, the transmission of electrical energy to the end user is ensured.

Safe contruction of energy lines and reducing energy loss to minimum is very important. Issues such as the cost of constructing power lines, the route of the transmission line, terrain condition, and the security element of the line are examined.
