Peakhurst Telephone Exchange

Southern Cross Switchboards has recently completed a range of switchboards for the Peakhurst Telephone Exchange project, which is part of the National Broadband Network (NBN) rollout. Among the switchboards are 1 x Main Switchboard, 1 x Standby Generator Plant (SGP) Enclosure and 1 x Mechanical Services Switchboard.

The SGP Enclosure is a simple enclosure that houses an Isolator, which is supplied from a 350kVA Generator Set and feeding the Main Switchboard as the Generator Supply. The Main Switchboard on the other hand is Dual Supply 630A and is constructed to Form 3B as per AS/NZS3439.1 with a Fault Level of 50kA for 1 Second. The outgoing supplies consist of an Automatic Transfer Switch which transfers between the Generator and Mains supplies. The scope of works also included requirements to incorporate Telstra’s Alarm Monitoring System (AMS) in the Main Switchboard. Last but not least, the Mechanical Services Switchboard is a whole new ball game compared to the Main Switchboard. There are lots of control equipment and wiring required.

Similar to most projects associated with the NBN, Peakhurst Telephone Exchange had a very tight time line to completion. This has once again proven to be welcome challenge for Southern Cross Switchboards to complete all three switchboards in the limited time frame given and making sure the quality of the switchboards was not compromised.

Like all things in life, there were several obstacles along the way which set us back but nonetheless, Southern Cross Switchboards still managed to rise to the occasion and complete all three switchboards in the given time frame. Most importantly, we managed to keep our client happy.

Value: $59k
