Providing tailored electrical power solutions to the African market has positioned Trafo Power Solutions as a key player in the region. The company’s success is rooted in its deep expertise, extensive experience and thorough understanding of the needs of mining operations across the continent. This has enabled Trafo Power Solutions to meet the unique challenges associated with electrical power supply in these harsh and demanding environments.

One of the company’s latest projects highlights its ability to provide specialised transformer solutions suited to the rigorous conditions of mining applications. Trafo Power Solutions recently supplied nine transformers to an electrical contractor for installation at a mineral sands operation in Mozambique.

This delivery included seven 800 kVA transformers designed for skid mounting, ensuring ease of mobility across the expansive mining site. The remaining two units, rated at 160 kVA, will be pole-mounted. All transformers in this order are rated at 22 kV to 415 V, aligning with the site’s specific voltage requirements.

David Claassen, Managing Director of Trafo Power Solutions, explains that this latest order follows a previous successful supply of four dry-type transformers directly to the mining operation. The earlier batch included 3150 kVA transformers, also rated at 22 kV to 415 V, and installed within IP23 enclosures. These transformers were equipped with the necessary control and protection equipment to ensure robust performance in the highly corrosive operating environment of the mineral sands mine.

“The mineral sands mining environment is particularly harsh, with high humidity and salinity levels that can accelerate corrosion. Our transformers are specifically designed to withstand these conditions, ensuring longevity and reliability in such an aggressive setting,” says Claassen.

A key factor in this repeat business was the mine’s confidence in the performance of the previously supplied transformers. “When the need arose for additional transformers, the customer specifically requested Trafo Power Solutions, which underscores our commitment to delivering quality solutions that meet the exact needs of mining operations,” Claassen adds.

One of the critical design considerations for these transformers was minimising electrical losses while ensuring the ability to handle large non-linear loads from the mine’s Variable Speed Drives (VSDs). These transformers were engineered according to SANS 780 Edition 5.1 standards to achieve the lowest possible losses. Additionally, due to the site’s known voltage supply instability, the transformers were designed to withstand fluctuations while maintaining consistent and reliable power.

Aside from the technical specifications, the project also posed significant logistical challenges. The remote location of the mine required careful planning to ensure the seamless transportation and installation of the transformers. “Logistics is always a key factor when supplying equipment to mining operations in remote areas. We worked closely with our partners to ensure a smooth delivery process despite the challenges,” says Claassen.

Further reinforcing its relationship with the electrical contractor and the mine , Trafo Power Solutions has secured an additional order for 18 transformers, which are scheduled for delivery by the third quarter this year. This ongoing partnership underscores the company’s reputation as a trusted supplier of high quality, purpose-built transformers tailored for mining applications in Africa.

As Trafo Power Solutions continues to expand its footprint across the continent, its commitment to delivering reliable, durable and efficient electrical power solutions remains at the forefront of its strategy. With a strong focus on engineering excellence and a deep understanding of mining conditions, the company is well-positioned to support the sector’s evolving power infrastructure needs.
