The new 6.5 kilometer 66 kV “Goolwa to Middleton” line utilized Helsinki size ACCC Conductor mounted on steel monopoles replaced an older line where corrosion had taken its toll. The lines, which were moved to a new position are made from ACCC Conductor which has greater strength, less sag and is better suited to harsh coastal conditions with the bonus of needing fewer poles to carry the weight.
In the next ten years, SA Power Networks plans to build a new substation at Middleton to meet the growing power demand in the area and have coordinated current maintenance with future plans to keep costs and impacts for electricity customers as low as possible.
The work was done before the busy summer tourist season to minimize any disruption to holiday plans.
The average span was approximately 300 meters with the longest span at 424 meters. ACCC Conductor for the project was supplied by Taihan and hardware was supplied by PLP. SA Power Networks did their own engineering and construction.
SAPN crews used Tesmec pullers and tensioners. ACCC Master Installer Shariffudin Abdullah provided preconstruction training and project review. Michael Parr of SAPN reported that the project went well with no issues.
The project supplies 8,000 residents and businesses in the Goolwa community.
