The Sawyers Valley solution
Release Date: 20 December 2007
The finishing touches to Western Power's reliability upgrade of Sawyer's Valley are nearly complete ready for the expected increased use in power over the summer peak.
The $2.4 million project designed to improve the power reliability to Sawyers Valley and Chidlow includes the installation of 8524 metres of new overhead power lines and 1100 metres 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.
"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.
"By bundling the cables together and insulating the lines, we significantly decrease the chances of a power interruption caused by a falling branches, flying debris and birds," Ms Chapman said.
She said the extra investment was worthwhile for the community and Western Power.
"These special lines are a little more expensive but they are worth while," she said.
Ms Chapman said the Sawyers Valley project illustrated Western Power's commitment to improving the reliability of power supplies to rural and semi-rural customers.
"We believe these measures will improve power supplies to our customers in Sawyers Valley and Chidlow," Ms Chapman said.
