The newly established Stefanutti Stocks Power Division successfully secured the award of its first major project. ESKOM required considerable restructuring of the existing electricity grid to ensure security of supply during the 2010 Football World Cup. In some instances the supply of power was diverted onto new lines.
The restructuring of the existing grid included the tie-in of 400 kV and 765 kV power lines at the Majuba Power Station near Volksrust. This also entailed the installation of foundations, erection and stringing of two 400 kV lines and one 765 kV line, as well as the dismantling of portion of the existing Majuba-Venus 400 kV line.
The 765 kV terminal tower foundation is made up of 180m3 of concrete and weighs 78 ton. The lift of this tower was done in three sections, using a 150 ton crane.
“Work progressed continuously since the beginning of February in order to meet the three shutdown dates that were programmed over three week-ends in April,” says Roger Venzo, from Stefanutti Stocks. “Despite time lost due to rain which resulted in lack of access with heavy plant, the program ran on time. A feat which is due to the commitment of our team.”
The project was successfully completed at the end of April.
