    Trafo mini substations for Zambian copper mine: design and power density notes

    March 31, 2026|

    Reviewed by Joe Ashwell

    First reported on International Mining – News

    30 Second Briefing

    Trafo Power Solutions is supplying seventeen specially engineered underground mini substations to a Zambian copper mine, comprising a mix of 800 kVA and 1,000 kVA units. The oil-cooled transformers are housed in compact, rugged enclosures designed for constrained haulages and high dust and moisture, with protection and switching gear integrated into each skid-mounted package. For mine electrical teams, the key impact is higher installed power density close to the working faces, reducing cable runs and voltage drop while keeping maintenance concentrated on modular units.

    Technical Brief

    • Orders comprise multiple 800 kVA and 1,000 kVA underground-rated mini substations from Trafo Power Solutions.
    • Units are custom-engineered for a specific Zambian copper mine’s electrical distribution and layout constraints.
    • Customisation scope reportedly included precise matching to the mine’s operating voltages and protection philosophy.

    Our Take

    Trafo Power Solutions also supplying a skid‑mounted mobile substation to an Australian mine (3 February 2026 item) suggests the company is building a niche in modular power packages for remote or constrained sites, which can shorten electrical infrastructure schedules for copper operations in Zambia.

    Within our 1183 Mining stories, copper pieces frequently highlight power reliability as a bottleneck in African underground mines, so deploying multiple 800 kVA mini substations signals an effort to decentralise and harden mine‑level distribution rather than relying solely on surface or grid infrastructure.

    Founders Factory–Rio Tinto mining tech cohort: deployment signals for mine operators

    Founders Factory and Rio Tinto have backed six new mining-technology startups through their accelerator, selected from more than 500 applications received in four months as demand for raw materials intensifies across exploration, processing and critical mineral recovery. The cohort targets digital and hardware solutions spanning orebody discovery, plant optimisation and recovery of low-grade or complex ores, signalling strong investor appetite for deployable tools rather than pure R&D. For mine operators, this points to a near-term pipeline of pilots and site trials, particularly around data-driven processing control and improved critical mineral extraction.

    Gold Fields’ Sandvik 66 t diesel-electric trial at St Ives: design notes for mine engineers

    Gold Fields will pilot a prototype Sandvik 66‑tonne diesel‑electric underground haul truck at its St Ives gold operation in Western Australia, as outlined in its Sustainability Report 2025. The trial, to be conducted with mining contractor Byrnecut as “business partner”, will test high‑capacity diesel‑electric haulage in existing St Ives stopes and declines. Outcomes will inform fleet decarbonisation strategy, power demand planning and potential changes to ventilation design for future underground expansions.

    Epiroc 480 kW charging solution: power distribution insights for mine planners

    Epiroc has introduced a 480 kW underground charging system designed for heavy‑duty battery‑electric fleets, combining ruggedised hardware with OEM‑agnostic interfaces so mixed‑brand loaders and trucks can use the same infrastructure. The system uses dynamic power distribution to allocate available capacity across multiple connected vehicles, reducing peak demand and improving utilisation of limited mine power. For mine planners and electrical engineers, this points to higher charger throughput per substation bay and simpler standardisation of charging bays in constrained headings.
