Q4 delivers reliable outcomes for complex, high-capacity projects with demanding timelines and zero-tolerance failure points. The division was formed to address a clear market need: supplying high-volume main switchboards within compressed timeframes and with minimal risk.
The joint venture brings together SRS Power, Aline Group, Bentrol and Q4 Power Distribution. Combined, the group represents 350 staff and $345 million in revenue, bringing together significant Australian engineering, manufacturing and delivery capability.
The joint venture between Q4 and the following partners has been born from an identified gap in the sector to supply high volume, medium voltage, main switchboards in compressed timeframes with minimal risk.
Pre-Fabrication
One standard, many builders, built off-site.
Every board is pre-fabricated in the factory to a single non-proprietary Siemens standard, so appearance, layout and functionality stay consistent regardless of which JV manufacturer builds it. This multi-manufacturer production model lets large programs be distributed across the JV without stretching labour or blowing out delivery times, while off-site assembly removes work from the critical path and reduces on-site risk and time.
- Factory build to a single, non-proprietary Siemens standard
- Multi-manufacturer production model for consistency at scale
- Off-site assembly that reduces site risk and compresses program time
- Warehousing concept for the 5–10 most common board types
Backing Australian Manufacturing
Q4 is committed to Australian manufacturing and local supply, keeping capability, jobs and quality control here in Australia. This commitment runs through our Q4 Power Distribution capability, where switchboards and assemblies are manufactured locally. By sourcing and building domestically, we deliver equipment our clients can trust — with the traceability and accountability that local manufacture provides.
Site Installation
Built and installation expertise
Unlike other switchboard manufacturers, Q4 are a fully fledged EBA business, so we can supply the fully design, build and install solution. We design the boards so that they are easy to install and maintain and so that they can be installed by the Q4 team across any industrial landscape throughout Australia. The benefits that this unique service provides the client include:
Free Issue Equipment Installation
Expert care and installation of other critical equipment
With extensive experience and specific training from most OEM electrical component suppliers, Q4 offer a fully warranted “Free Issue Equipment” installation service to the end client. Providing the critical onsite link between the overseas manufacturers and onsite installation, Q4 work closely with the end client and OEM manufacturer to take responsibility for the installation of overseas-procured assets including:
Testing & Commissioning
The Independent Commissioning Agent
More than the standard Factory Acceptance Testing (FAT), Q4 offer the client the highest level of verification and functional testing before all switchboard assets leave the factory. We then provide full, rigorous onsite level 3–5 commissioning and testing to ensure the assets are failsafe and secure. Our onsite teams complete all commissioning using quality calibrated digital testing and recording equipment for testing validation. The Q4 testing and commissioning process provides considerable benefits, including:
Manufacturing
Shared capacity, single standard, serious scale.
The JV draws on a 190+ workforce across four Victorian plants, enabling rapid scaling, workload balancing and resource sharing so no project stalls waiting on a single line. Every board is built on the Siemens SIVACON platform with SENTRON 3WA breakers, assembled from Australian BlueScope steel to the highest Australian standards. Backed by the JV’s combined 350 staff and $345m revenue, this model delivers rapid, consistent and repeatable output for stage-based data-centre programs where volume reliability matters.
- 190+ workforce across four Victorian manufacturing plants
- Siemens SIVACON switchboards with SENTRON 3WA air circuit breakers
- Australian-made using BlueScope steel
- JV scale of 350 staff and $345m revenue for reliable, repeatable output
