In this paper, the structural design of 132kV HV lines is addressed at the conceptual level, where concept design and support types for HV lines are discussed. We explore the importance of selecting the correct support design philosophy, which is suited to the terrain and risks associated with the area. Here we explore the difference between guyed and non-guyed steel poles and lattice towers, and illustrate the large variations in life-cycle cost associated with each of the 4 support types. Recommendations are given for where such structure types would be ideally suited, with specific reference to uniquely African considerations such as member theft.
