Meeting the power demands of a critical government defence project requires more than good equipment. It requires rigorous quality assurance, proven manufacturing capability and the confidence that comes from seeing it tested in person.
Brunstock recently completed factory acceptance testing (FAT) for four 66/11 kV, 60/40 MVA oil-immersed power transformers, manufactured to order for an Australian government defence application. A Brunstock electrical engineer travelled to the Brunstock transformer facility in China to witness the testing firsthand—an essential step on a project where strict lead times and zero tolerance for failure are non-negotiable.
What is factory acceptance testing?
Factory acceptance testing is the process of verifying that equipment meets all specified technical, performance and quality requirements before it leaves our manufacturing facility. For high-voltage power transformers destined for critical infrastructure, FAT provides clients with documented assurance that each unit has been tested under controlled conditions against the agreed-upon specification—before it is shipped, installed and energised.
On this project, FAT was not simply a formality. With programme deadlines tied to a government defence facility’s operational requirements, every stage of the manufacturing and testing process was carefully managed to ensure on-time delivery without compromising quality.
The equipment
The four transformers are 66/11 kV, rated at 60/40 MVA, oil-immersed units built to Brunstock’s high-voltage specification. Brunstock’s 66 kV transformer range features a bell-type tank construction with corrugated shell for strength and thermal performance, a D-shaped yoke core with 45° mitre joint for reduced losses, and a winding layout supported by interior and exterior strips with high-tension cardboard cylinders between coils for short-circuit withstand capacity.
Full specifications for Brunstock’s 66 kV power transformer range are available at brunstock.com/66kv-electrical-transformers.
On the factory floor
Brunstock engineers worked closely with the factory team throughout the FAT process, reviewing test procedures, witnessing performance testing, and confirming that all documentation was in order for Australian delivery. The factory’s capability and attention to detail throughout the process reflected the standard of manufacturing Brunstock is built on.
All four units passed FAT successfully and are on track for delivery to site within the project’s required programme.
Brunstock and defence infrastructure
Defence and government projects require tight timelines, rigorous specification compliance and confidentiality. Brunstock’s ability to manufacture, test and deliver high-voltage power equipment to these standards positions the company as a trusted partner for critical infrastructure projects across Australia, Europe and South Africa.
