For economic reasons, our next generation overhead power transmission line towers will be built with new design concepts in order to reduce the weight of the support structures. This paper discusses the computer aided design and analysis carried out on a 220 kV Single Circuit transmission line tower built with a combination of Circular Hollow Sections and Angle sections rather than built with only Angle sections. After optimization, the comparative study is presented with respect to stresses, deflection and weight of both Circular Hollow Sections and Angle sections towers. There is a saving in steel weight up to 8% resulted when a Circular Hallow Section tower is compared with an Angle Section type. The analyses results are compared with full scale test carried out at Central Power Research Institute (CPRI) Bangalore, India are presented.

Abstract


For economic reasons, our next generation overhead power transmission line towers will be built with new design concepts in order to reduce the weight of the support structures. This paper discusses the computer aided design and analysis carried out on a 220 kV Single Circuit transmission line tower built with a combination of Circular Hollow Sections and Angle sections rather than built with only Angle sections. After optimization, the comparative study is presented with respect to stresses, deflection and weight of both Circular Hollow Sections and Angle sections towers. There is a saving in steel weight up to 8% resulted when a Circular Hallow Section tower is compared with an Angle Section type. The analyses results are compared with full scale test carried out at Central Power Research Institute (CPRI) Bangalore, India are presented.
