Powerlink plans 92-tower 275kV 132kV expansion of Ingham -Tully transmission line |
First 10 of 10 paragraphs shown The proposed replacement transmission line was 95km long and up to 60m wide, located between the existing substations at Ingham and Tully in Far North Queensland over agricultural land and National Park Listed as part of the Wet Tropics of Queensland. Across Cairns and Townsville: The transmission line passes through the Cassowary Coast & Hinchinbrook Shires between Cairns and Townsville regional centres. Exiting easement width doubled: The existing 132kV transmission line that runs between Powerlink Queenslands Ingham and Tully substations has operated is built on easements which are 20 metres wide, although clearing in vegetated areas has generally been carried out to a width of 30 to 40 metres to ensure the safe operation of the line. Expanded to 60 metres wide: Due to the upgrade of the line to include both a 275kV and 132kV component, the replacement line requires easements which are 60 metres wide to ensure it complies with current safety standards (Electricity Safety Act, 2002). Therefore, the existing cleared corridor will need to be widened by up to 30 metres. For industry in Ingham, Cardwell, Tully, Cairns: The replacement line will initially be operated at 132kV, with a capability for one circuit to be operated at 275kV in the long term, as electricity demand increases. The plan: Powerlink Queensland (Powerlink) is proposing to carry out a replacement of the 132kV transmission lines between Ingham and Tully in Far North Queensland with a new 275/132kV dual voltage transmission line. The action to be carried out is the decommissioning of the existing line, followed by the construction, operation and maintenance of the replacement high voltage (275/132 kV) transmission line; - the Ingham to Cardwell section of the line will be constructed first, followed by; - the Cardwell to Tully section; - Construction will take approximately 24 months. The operational life of the new transmission line was estimated as 50 years. ...Log in to read rest of Article or image. |
