Do you provide both standard and custom transformer builds?

Yes. We offer standard configurations and fully custom designs to meet specific voltage, kVA, and environmental requirements.

Where are your transformers manufactured?

All products are designed, manufactured and tested in our Melbourne-based facility.

What industries do you serve?

We supply industrial, mining, renewable, data center, defence, and rail projects, among others.

How quickly can you deliver?

Lead times vary by size, but we maintain high stock levels to enable fast turnaround. We will provide you with accurate leadtimes when we provide your quote. Critical leadtimes are generally achievable, but may incur a production disruption surcharge.

Can you assist with specifying the right transformer?

Yes. Our engineering team will review your application and provide sizing and specification support.
