Office Location Eskom Megawatt Park1 Maxwell driveSunninghill2157 Email Address skosanb@eskom.co.za Scope Details The Athene Hillside Impala 1 & 2, 132kV Bypass Lines are situated in the Richards Bay area, a marine and industrial environment (highly corrosive), resulting in the tower members, bolts and hardware being heavily corroded. Some of the members have corroded to the extent that some members have actually fallen of the tower. Corrosion of the tower members, bolts and hardware decreases its mechanical strength thus decreasing the mechanical integrity of tower as a whole which in turn increases the risk of hardware failure and tower failure. In order to eliminate the aforementioned risk it was decided that the Athene Hillside Impala 1 & 2, 132kV Bypass Lines be refurbished. The scope of the refurbishment will include replacement of six towers (four 224 C towers and two 224B towers), refurbishment of two beams (433D tower type) and the replacement of all insulators and selected hardware. The existing quad tern conductor will be maintained. No new joints or conductor will be required. The existing towers will be removed in stages as the new towers will be erected. Line 1 has 2 x 48 core long span All-dielectric self-supporting cable (ADSS) installed which will be re-routed, via an acceptable design, during the replacement of the towers. The aim is to replace both existing ADSS fibre with new from Tower 2 to Gantry at Impala. This report highlights the current state and recommended processes to be further designed for the refurbishment.
