We are proud to announce the successful completion and commissioning of a critical Power Distribution Box and Transformer system for the Mali Project. This milestone underscores our commitment to delivering robust and reliable electrical infrastructure for the mining industry, even in demanding environments.

The project's centerpiece is a high-capacity, 1250 kVA, 11kV/0.4kV power transformer (specification: Z11-1250/11+4x2.5%/0.4, Dyn11 vector group) with an impedance of UK=8.75%. This specialized transformer is engineered for exceptional performance and efficiency, ensuring a stable and high-quality power supply essential for the mine's heavy-duty operations.

Housed within a custom-built Power Distribution Box, this system forms the heart of the site's electrical network. It is designed to step down high-voltage incoming power to usable levels for various mining equipment, processing machinery, and site facilities, guaranteeing operational continuity and safety.

Key Project Highlights:

• Robust Transformer: The 1250 kVA unit features multiple tap changers (4x2.5%) for voltage regulation, ensuring consistent performance despite fluctuations in the incoming grid supply.

• Custom Enclosure: The distribution box provides a secure and protected environment for the critical electrical components.

• Proven Reliability: This system is built to the highest standards, designed to withstand the challenging conditions of a mining operation.

Engineering a Resilient Power Backbone

At the core of this achievement is the delivery and installation of a fully integrated power distribution solution. The system is built around a high-performance 1250 kVA, 11kV/0.4kV distribution transformer, custom-engineered to meet the rigorous demands of the mining sector.

Key technical specifications and project scope included:

• High-Capacity Transformer: A Z11-1250/11 transformer with a Dyn11 vector group, ensuring stable voltage conversion from the 11kV grid to the 400V used by site machinery.

• Precision Voltage Regulation: Equipped with 4x2.5% tap changers, the system intelligently maintains optimal voltage levels, protecting sensitive equipment from damaging fluctuations common in remote grid connections.

• Robust Protection: With an impedance of UK=8.75%, the transformer is optimally designed to handle fault currents, safeguarding the entire electrical network.

• Integrated Power Distribution Box (PDB): The transformer is housed within a custom-designed, secure PDB. This enclosure serves as the central nervous system for the site's power, distributing electricity efficiently to crushers, conveyors, processing plants, and other critical loads.

Overcoming Challenges to Ensure Operational Excellence

Executing a project of this scale in a remote mining location required meticulous planning and expert logistics. Our team managed the entire process, from the careful international shipment of the major components to the precise on-site installation and commissioning, all while adhering to the highest international safety standards.

"This project was about more than just delivering hardware; it was about delivering certainty. "We understood that any delay in the power system would mean a delay in our client's production. Our team's expertise ensured a seamless, on-schedule deployment, providing the mine with a power foundation they can depend on for years to come."

The successful energization of this system marks a significant step forward for our client's Mali Mine Project, providing the dependable power foundation required for their production goals. Our team's expertise in engineering, procurement, and construction ensured a seamless project execution from concept to completion.

We congratulate our dedicated project team and thank the client for their trust and collaboration.
