Overhead Transmission Lines have to be supported with durable, strong and reliable structures. These structures has to be cost efficient too. The current optimal solution is steel, as in many fields of construction. The geometry of these structures is very important as well. The polygonal-section poles have been the most common structures in this sense. These poles are used for street lighting, stadium lighting and many other purposes. Polygonal poles are used in power networks too. Fabrika Enerji offers a variety of polygonal poles for power networks. These poles can be modified to meet the field conditions and the safety standards, along with the teshnical needs.
