No bird strikes in indoor switchroom

Major Power Networks’ upgrades are underway in Tennant Creek, in the Northern Territory, with the groundwork laid in preparation for the delivery of a new 22kV indoor switchroom.

Power and Water Corporation’s general manager power networks John Greenwood said the switchroom will house safer and more reliable switchgear, replacing the aged outdoor 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,” he said.

“The switchroom is being constructed by specialist contractors offsite and will be delivered to Darwin initially, where it will undergo intensive testing.

“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,” he said.

Mr Greenwood said switchgear 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 $4.76 million.

Following the testing phase, the building will be transported to Tennant Creek in early 2015 and installed and commissioned by August 2015.
