Western Power's Sawyers Valley Upgrade Nears Completion

Posted on: Friday, 21 December 2007, 09:00 CST

Australia-based utility Western Power has announced that the reliability upgrade of Sawyers Valley project is almost complete and ready for the expected increased power supply in the summer peak.

The A$2.4 million project, which was designed to improve power reliability to Sawyers Valley and Chidlow in western Australia, includes the installation of 8,524 meters of new overhead power lines and 1,100 meters of underground power cables.

Western Power spokesperson Marisa Chapman said that innovative solutions were needed to combat power interruptions caused by falling branches in Sawyers Valley.

Ms Chapman said: "Sawyers Valley has a high concentration of tall trees so Western Power used a new type of covered powerline called Aerial Bundled Cabling, which insulates the lines and helps prevent branches causing a power interruption.

"The new overhead lines in Sawyers Valley are now insulated whereas most powerlines in overhead networks are exposed. The insulated lines are bundled together like a liquorice twist and are used in heavily vegetated areas where vegetation is a large contributor to power interruptions."
