Trafo Power Solutions mobile substation: deployment and design notes for mine engineers

30 Second Briefing
Trafo Power Solutions has designed and supplied a skid‑mounted mobile substation for an Australian mine, providing a transformer and associated switchgear on a single transportable base for rapid deployment. Managing Director David Claassen says the in‑house engineered unit is built for harsh mining conditions, with a robust steel skid, integrated cooling and protection systems, and plug‑and‑play terminations to minimise on‑site installation time. The solution allows the mine to relocate power infrastructure as pits advance, reducing civil works and downtime during reconfiguration.
Technical Brief
- Design leverages Trafo’s prior experience supplying transformers and substations across mining and industrial sectors.
- Electrical configuration integrates transformer and switchgear to Trafo’s standard protection and control philosophy.
- Cooling arrangement and enclosure specification tailored for abrasive dust, vibration and thermal cycling typical of open pits.
- Mechanical interfaces and lifting points detailed to withstand repeated relocations without frame distortion.
- Similar skid-based substations are increasingly used on multi-pit operations to defer permanent substation civils.
Our Take
Australia features heavily in our Mining category, and mobile substations like this one are increasingly used there to shorten pre-strip and early works schedules on remote projects where grid extensions lag mine development.
For product-tagged pieces in our database, modular power solutions are often paired with temporary or contract mining fleets, suggesting Trafo Power Solutions is targeting mines that want to defer permanent electrical infrastructure until resource confidence or mine life is better defined.
With no specific commodity tied to this Australian deployment, the mobile substation concept is likely being pitched as commodity-agnostic infrastructure, which can be redeployed between sites and thus appeal to multi-asset operators managing shifting project pipelines.
