Southern Cross Switchboards manufactured two 1600amp, 36kA, IP42 motor control centres for the new Western Sydney Airport Fuel Farm. Our works have been designed in coordination with the Early
Works Foundations design, Building Works design and Fuel Works design to
capture monitoring, control and safety provisions for fuel farm operations, hazardous area equipment
requirements, fuel hydrant main leak detection system software and fuel farm emergency shutdown sequence. This design package focused on the aviation fuel control and automation system elements of the fuel farm and the fuel hydrant main.
Both MCC’s were over 6m long and required 1 shipping split which required us to attend the site and carry out the jointing of the sections, It is a big place and looks very impressive.

In July 2022 Southern Cross Switchboards were contacted by an established client to urgently design & perform site remediation works for a recently installed Main Switchboard at a brand new Horsley Logistics Park in Western Sydney.
The new scope of works was introduced after Southern Cross Switchboards had already designed & delivered the Main Switchboard. Power cabling was already terminated & the scheduled electrification date had to be delayed to accommodate for the revised works.
The timeframe issued by the client was 2 weeks completion from first contact, so there was no option of failure if the objective was to be achieved.
The task: Provide a staggered MCCB motor closing & opening circuit for (x6) existing 800A circuit breakers that also accepts an external 230VAC GPO supply on top of a 230VAC Uninterruptible Power Supply in the event of the Mains Power Supply failing during operation.
Immediately a high priority was placed on this & existing projects were reassigned to ancillary team members to temporarily carry out.
Within 3 days of receiving the desired scope the circuitry was designed & Bill Of Materials prepared. With the clients timely review & approval sign off it was onto the manufacturing stage.
A wiring harness was assembled with plenty of cable slack to reach the intended MCCB cells. Existing motor wiring on site had to be modified to accept the staggered-timers.
UPS & custom bypass switches were promptly ordered & prepared to make the installation on site as quick as possible.
Existing Automatic Transfer Switch wiring was also modified on site to have a tap-off 230VAC voltage supply for the MCCB motors.
Installation on site was done by the Southern Cross Switchboards team in the early hours of the morning, conducted under mobile spotlights, to prevent existing services disruption.
With very low visibility on a bitterly cold winter morning, with overcast clouds completing a background of gloom it took an entire day to install the custom wiring harness & complete the necessary terminations.
One more day was required to perform routing testing & finalize minor wiring amendments to make the entirety work as intended.
A sequence test was performed once the client was satisfied with our routine testing & the new circuitry was functioning as intended on our first try. What a relief it was to see such an urgent retrofit project perform straight off the bat.

Keepit Dam is location on Namoi River 56km west of Tamworth. The project commenced in 1939, but halted in 1941 because of WW2. The project was finally completed in 1960. Keepit Dam was the 1st of the 3 dams built in Namoi River Basin. It is currently 55 m high, 533 m long and 48 m wide. The primary use of dam is irrigation in the Namoi Valley and water supply in Walgett.
Currently, Keepit Dam is undergoing 2nd stage of major upgrade. The project cost is 24 million and is scheduled to be finished by mid-2019. The project includes rising of the wall and embankment by approximately 3 m and strengthening the wall with post-tensioning anchors. As part of preliminary work a new substation T1 and main LV switchroom with standby generator off the dam wall were constructed.
Southern Cross Switchboards provided the main switchboard located inside the LV switchroom. The switchboard was floor mounted and rated 800A, 25kA, IP54 and form 4a. As per specifications the plinth was made of 100X50X6 rolled steel channel and hot dipped galvanized to a minimum thickness.
The Switchboard was successfully manufactured delivered on time to the site.
Telstra is Australia’s leading telecommunications and technology company. They offer wide range of communications services. Telstra in 1854 started with building the first telegraph line in Australia. Later with changing technology moved from telegraph to telephone line, and then from national communication to international communication.
In 2014 Telstra had a telephone exchange project in Mittagong. Mittagong, located in Southern Highlands is known for its stunning reserve and walking tracks. Southern Cross Switchboards provided Main Distribution Board (25kA, IP42, Form 3bih/4a, 160A). Originally they had asked for a MSB and DB, but our team had used their technical skills and experience to propose a design with 1 MDB that would fulfill the requirements for both.
The switchboard was constructed using Elsteel Type Tested Modular System. The plinth was painted gloss black with mouse-hole for lifting. Because of excellent team spirit we were able to deliver the board a day early. In feedback this act was highly appreciated.
Overall the feedback from our customer was positive. According to them our job was done before time with excellent accuracy.
