LH Marthinusen (LHM), a division of ACTOM and one of the largest global operations offering a comprehensive suite of on- and off-site electro-mechanical repair and manufacturing services, is completing the manufacture of two 30 MVA transformers for a mining house in Botswana.
LH Martinusen is set to supply two 30 MVA transformers to deliver reliable, high-performance power for a Botswana mine.
The new transformers will replace existing equipment which the mining house found to be no longer able to meet the demands of increased production capacity and operational reliability.
Chris Thoka, Divisional Sales and Marketing Manager at LHM, explains that ageing equipment, coupled with the growing need for stable, high-capacity power to support critical mining operations, prompted the company to seek a more robust solution that could ensure uninterrupted performance and long-term efficiency.
“The company conducted a competitive tender process to identify a supplier capable of meeting its stringent technical and operational requirements. LHM was selected after a comprehensive evaluation, a decision that reflects our strong reputation and proven expertise in delivering tailored, high-performance power solutions,” says Thoka.
“Our deep understanding of the unique operational challenges in the mining industry further strengthened the client’s confidence in our solution. Our ability to meet the required technical specifications, combined with our commitment to local support, after-sales service, and competitive pricing, positioned us as the preferred partner.”
The project requires LHM to deliver two 30 MVA transformers, engineered to handle high-voltage demand with a high level of reliability and efficiency. The transformers need to integrate with the mine’s existing infrastructure, comply with stringent safety and environmental standards, and support long-term operational sustainability. In addition, the solution is required to be delivered within a strict timeline to support the company’s production targets.
Thoka says, “We are in the final stages of manufacturing, with the transformers fully built and a few minor tasks to be completed before Factory Acceptance Testing (FAT). Our team is working closely with the mining house to ensure alignment with its operational timelines.”
Initial site assessments and preparatory work have already begun, and the delivery and installation plan is scheduled to roll out in the coming weeks. Although no significant challenges have arisen to date, LHM anticipates potential logistical complexities due to the remote location of the site.
“To mitigate this, we have implemented a robust supply chain protocol and are leveraging our local expertise to ensure smooth delivery and installation. Any challenges arising will be managed through proactive communication and the support of our experienced project management team. At this stage, we do not foresee any issues that could impact the project’s successful completion,” adds Thoka.
Benefits and cost savings
The transformers are designed to bring several benefits to the mine, including enhanced power reliability, reduced risk of downtime, and improved energy efficiency, all of which will support the mining house’s operational goals. Once installed and operational, the new transformers are expected to deliver significant cost savings through lower maintenance requirements and optimised performance, in turn boosting productivity across the site.
“This project underscores LHM’s commitment to supporting the Botswana mining industry with innovative, reliable, and sustainable power solutions. Our presence and industry expertise in Sub-Saharan Africa enable us to deliver tailored solutions that support operational success and to develop and maintain long-term partnerships. We are proud to contribute to the growth and sustainability of the mining sector across the SADC region,” Thoka says.
