High Voltage Transformers

Safe, reliable voltage — without compromise

When it comes to temporary power, getting voltage wrong isn’t an option. Equipment damage, costly delays and safety risks all stem from unstable or mismatched supply. For high-demand sites, the challenge isn’t just getting power on - it’s making sure it’s delivered at the right voltage, safely and reliably.

That’s why we go beyond simply supplying transformers. Instead, we design and deliver fully engineered voltage solutions, tailored to your site. From compact 110V tool transformers to multi-megawatt high-voltage step-up and step-down systems, our fleet covers the complete spectrum of site and grid requirements.

Every solution is backed by our certified electrical engineers, site-specific design, and the full range of switchgear and distribution equipment. So whether you’re powering a remote compound, feeding into the grid, or distributing HV across a major infrastructure project, you can be confident your voltage is stable, compliant, and built to perform.

Voltage solutions to match your site

We supply a complete range of temporary transformers for both low- and high-voltage applications - from compact site tools to multi-megawatt systems. Whether you need to step up to 11kV for long-distance distribution, step down to 230V for site equipment, or isolate sensitive loads, we have the right solution.

Our fleet includes step-up transformers for HV interfacing, step-down units for cabins and lighting, and isolation transformers for added protection on critical circuits - all backed by the expertise of our certified electrical engineers.

Engineered for critical environments

Our transformer systems are built for complex, high-pressure environments where safety, compliance, and uptime are critical. From planned grid shutdowns and utility upgrades to emergency restorations, they keep substations, rail networks, and critical infrastructure online.

On major construction sites, they enable safe distribution from high-output generators, while in remote or temporary locations they support step-up applications for long-distance transmission. With certified HV equipment, expert installation, and rapid deployment, we deliver reliable performance across 110V to 11kV — backed by full system support when it matters most.

Expert installation, end to end

High-voltage systems demand specialist expertise and rigorous compliance. That’s why every transformer we deploy is designed, installed, and tested by certified electrical engineers — ensuring voltage, load, and protection are precisely matched to your site. We manage correct earthing, isolation, switchgear, and safety devices so your system operates reliably and within regulations.

From site assessment and specification through to delivery, hook-up, and handover, we take care of the entire process. Our engineers integrate seamlessly with your infrastructure — whether generator farms, distribution rings, or utility grids — and provide monitoring and ongoing support to keep your system stable and compliant from start to finish.
