Abstract

This project presents a methodological approach, suggestion and information in uprating the existing 275kV transmission overhead line by using the re-conductoring approach. Overhead transmission line conductors were given priority in information. Calculation regarding the maximum sag and maximum current at maximum operating temperature were the core of this project as to suggest a novel conductor available in the current market. The aim of this project is to provide more current and less sag with the new conductor proposed in comparison with the existing. In addition, the conductor will not in any way infringe the minimum safety clearence. Smart Draw, Matlab and Excel were used as a medium in the data analysis. Therefore, the apparent power of the overhead transmission line when applied with the new conductor can be calculated as to achieve the objective of this project. In Malaysia, ACSR Zebra is used the conductor for the 275 kV L3 tower. Thus, four other conductors were chosen in order to make comparison between the maximum sag current at maximum operating temperature. These conductors are the 3M Drake, AAC Narcissus, AAAC Greeley and ACCC 415 mm2 which have similar characteristics to the ACSR Zebra in terms of weight, maximum rated strength ratib and size. By using the calculations provided in this project, it is determined that the 3M Drake conductor is better to the ACSR Zebra in comparison of the maximum sag and the current at maximum operating temperature.
