Abstract

Electrical transmission line is
it medium to carry power loads from one station to
another station, therefore, it is one of the most important projects in power business.
To maintain the reliability and safety of' the structure, the dynamic and static load
acting on transmission structure should be thoroughly studied before an efficient
design may be obtained. I ligh standard of design to cater effect of wind load must be
implemented to preclude any structural Ihilure which will interrupt the national grid
supply of power. The main objective of this study is to identify the behavior of
electrical transmission tower due to lateral wind forces. In addition, this study aims to
evaluate current design practice adopted by Tenaga Nasional Berhad (TNB) on its
adequacy and in optimization of their design. The study begins with comprehensive
research and literature review on behavior of transmission tower and conductor under
wind loads. A 132kV electrical transmission tower is identified for the purpose of
analysis. The calculation of design wind loads are in accordance with American
Society of* Civil Engineers (ASCE) 7-05 Minimum Design Loads for Building and
Other Structures. The electrical transmission tower is assumed located at
mountainous area with it wind speed of' 38 m/s and assessed as a global structure
under normal situation as well as under broken conductor situation. As the outcome
of the analysis, it design assessment of the transmission tower is provided.
Subsequently, the reliability of' TNB current practice of design and the design
adequacy is evaluated.
