Overhead
aluminium conductors used for both medium and high voltage installations are
flexible and uniform in weight along their lengths. They often take the form of
catenary changes with conductor temperature, ice and wind loading and time.
Adequate vertical and horizontal clearance under all weather and electrical
loading conditions are guaranteed by ensuring the breaking strength of the
conductor is not exceeded. Thus, the behaviour of the conductor catenary under
all conditions need to be incorporated into the transmission line in the
constructional design regardless of the length of the transmission line.
Overhead transmission lines constructed across water such as Lagoon are good
illustration of the characteristics described above. Therefore, this research
presents a case study of 33kV overhead line construction crossing 265 m wide
‘Lagoon’ which requires Sag parameter calculations. Detail description of the
case study, specifications for Aluminium conductor steel reinforced (ACSR) type
A1/S1A IEC 61089 standard and sag calculations with and without wind or ice
weather conditions are presented. The design calculation for weight of a
required Dead-End Lattice Tower via determination of weight of the individual 5
components of a Tower are also presented. The obtained results are presented
and discussed. The Sag parameter results and that of Dead-end lattice tower and
its components weights evaluated were applied to the proposed project. The
method of this research work generated reliable results suggesting that it can
be applied to any other Transmission tower successfully.
