Trafo Power Solutions’ African growth: dry-type mine power systems for engineers

30 Second Briefing
Trafo Power Solutions is expanding its African footprint in mining and other heavy industries on the back of dry-type transformers and modular electrical infrastructure tailored for harsh, remote sites. The company is leveraging containerised, factory-tested MV/LV substations and skid-mounted transformer packages to shorten project schedules and simplify deployment for new mines and plant expansions. For engineers, the focus is on reduced fire risk versus oil-filled units, lower maintenance, and strong in-country technical support for design, commissioning and lifecycle service.
Technical Brief
- Dry-type transformers are specified for underground mining, where oil-filled units pose unacceptable fire and smoke hazards.
- Trafo’s modular substations are factory-acceptance-tested, reducing on-site energisation risk and commissioning errors.
- Enclosures are engineered for dust, moisture and corrosive atmospheres typical of African open-pit and plant sites.
- Designs incorporate forced-air or natural ventilation schemes to control transformer temperature without combustible cooling media.
- Remote and brownfield mines use skid or container modules to minimise hot work and high-voltage terminations on site.
- Wider adoption of dry-type, modular MV/LV systems in African mining could progressively reduce transformer fire incidents.
Our Take
In our database, Trafo Power Solutions’ recent work ranges from underground mini substations at a Zambian copper mine to dry‑type transformers for a major Pakistani copper‑gold project, signalling that its African growth push is backed by multi-continent reference sites in demanding mining environments.
The mix of oil‑cooled underground units in Zambia and dry‑type transformers in modular e‑houses suggests Trafo is positioning itself as a flexible supplier across both high‑fire‑risk and harsh underground settings, which is directly relevant to the ‘Safety’ and ‘Product’ focus of this Africa‑centred piece.
