Abstract

The overhead power line system is an important system that transmits power from the source to the load. The demand for electric energy transmission is increasing due to population growth, development of transport technology and the economic expansion, which are cause of overload of the overhead line system (OHL). Therefore, increasing the transmission capacity of the power lines is a practical solution to meet energy demand problems. However, the commonly used Aluminium Conductor Steel Reinforced (ACSR) line expands and deflects, increasing resistance as the transmission capacity increases, causing overheating because of the disadvantage of having a high coefficient of thermal expansion. To increase the transmission capacity of systems without building new transmission lines is to replace the ACSR wire by Aluminum conductor Composite core (ACCC®) wire. The carbon fiber composite core is up to 25% stiffer than the steel core, greatly reducing the deflection of the ACCC® line at high temperatures. This means that ACCC® conductors can carry higher capacity while deflection less than ACSR cables. In this paper, the authors performed sag-tension simulations of ACCC® cables using Conductor Comparison Program Software and the results compared with conventional wires using ACSR in the same working conditions.
