Another field of activity of Faragstar company is the engineering and implementation of transmission and distribution lines that are placed underground. Such lines are implemented in two ways, buried and placed in canals that are built for this purpose. These lines do not harm the beauty of the environment, and because they are not accessible, they will have much less risks than air lines, and because no privacy is defined for them. They are very useful in narrow residential areas. Scientifically, these lines have low series reactance and are suitable for high load densities. This company has completed the implementation of more than 1000 kilometers of underground cabling.
