Major Power Networks’ upgrades in Tennant Creek, NT, are officially underway, with the ground work laid in preparation for the delivery of a brand new 22kV indoor switchroom.
According to General Manager of Power Networks, John Greenwood, “This important project is part of Power and Water’s ongoing commitment to improving the security and reliability of the electricity network in regional areas.”
“The new indoor switchroom will house safer and more reliable 22kV switchgear replacing the aged outdoor 22kV switchyard.”
“Having an indoor switchroom means that the equipment is protected from dust, weather conditions and bird strikes, which are particular issues in Tennant Creek.”
“The switchroom is being constructed by specialist contractors offsite and will be delivered to Darwin initially, where it will undergo intensive testing. Local contractors are being engaged to complete the initial civil works.”
“Other upgrades already completed include the automation of the Ali Curung Line Feeder 2, replacement of old high voltage pot heads and the fitting of bird protection devices aimed at reducing bird strikes on key infrastructure.”
Mr Greenwood said switchgears are essentially circuit breakers that operate to clear faults on the overhead line feeders. The new indoor switchroom project was initiated in 2013 and the overall investment at its completion is estimated at $4.76million.
Following the testing phase, the building will be transported to Tennant Creek in early 2015 and installed and commissioned by August 2015.
