Increasing efficiency by using composite core aluminum conductor in energy transmission lines

For over a century, steel core in overhead line conductors has been used to increase tensile strength, provide longer spacing between short bearing structures, and reduce temperature-induced sagging of bare overhead conductors. Along with the developing technology, many researches and apps are carried out on conductors, which are one of the most important elements in the transfer of energy. It is aimed to increase the efficiency of power systems in subjects such as providing the opportunity to work at high temperatures by using conductors with different technologies on overhead lines, increasing the current carrying capacity, improving mechanical strength and reducing deflection. With the developments in High Temperature Low Sag (HTLS) conductor technologies, it has been possible to design efficient energy systems. Basically, HTLS conductors with high current carrying capacity at high surface temperature also increase reliability with their low deflection value. In addition, despite their high cost, reducing losses, being suitable for the use of different pole types etc. When the parameters are taken into consideration, suitable economic solutions can be produced. Today, studies are carried out to prefer high technology composite core aluminum conductors (HTLS) instead of traditional steel core aluminum conductors (ACSR) on many transmission lines that need high carrying capacity. The tests performed during the use of HTLS conductors are handled in two phases: laboratory tests and field tests. In field tests, thermal resistance, determination of deflection value, determination of tensile strength, current carrying capacity, etc. while conducting studies, the conductive structure and strength can be tested in the laboratory environment. In this thesis, the data obtained from a real application using composite core aluminum conductors (ACCC), a type of conductors with high temperature tolerance and low sagging (HTLS), in overhead lines were analyzed and the efficiency of the conductors was investigated. In this context; the double-circuit energy transmission line, called ALANYURT and KÖYLER Feeders, which is produced for the first time in Turkey and receives energy from the İnegöl Transformer Center within the borders of Bursa Province, İnegöl District, has been determined. Current, active and reactive power states, voltage drop, line loading and line losses for both HAWK and LISBON conductor facility conditions of this line were examined in detail, the results obtained were compared and the benefits of composite core aluminum conductor structures in terms of operation and efficiency were discussed.
