Project Overview
In Arianou, Côte d’Ivoire, a new mining operation required a scalable and resilient power distribution system to support processing equipment, lighting, and control systems across its remote site. With limited space for electrical infrastructure and exposure to dust, humidity, and voltage fluctuations, the client prioritized compact, durable transformers that could deliver consistent performance with minimal maintenance.
Key project requirements included:
Small physical footprint to fit within constrained mine-site substations
High reliability under continuous operation in a harsh tropical environment
Simplified maintenance design due to limited on-site technical staff
Compatibility with existing 11 kV medium-voltage network and 0.4 kV low-voltage loads
TSTY Electric’s Customized Solution
TSTY supplied 80 units of purpose-built, oil-immersed distribution transformers engineered specifically for mining applications. Each unit featured full copper windings, enhanced sealing against dust and moisture, and a compact tank design—ensuring long-term reliability while meeting the spatial constraints of the mine’s electrical layout.
Core Technical Adaptations
Full copper windings for low losses, high efficiency, and thermal resilience under variable loading
Compact tank geometry optimized for transport and installation in tight mine-side enclosures
IP54-rated bushing enclosures and breather systems to resist dust ingress and humidity
Standardized mounting dimensions compatible with common mining switchgear and protection relays

Engineered for Africa, Validated Globally
In remote mining operations, every component must earn its place—through durability, simplicity, and unwavering performance. This deployment succeeded by aligning engineering precision with real-world operational demands.
Designed for Space-Constrained Sites
The compact transformer design allowed efficient use of limited substation space, enabling faster civil works and easier integration into modular mine power systems.
Built to Withstand Harsh Conditions
Enhanced sealing and corrosion-resistant finishes ensured reliable operation despite constant exposure to airborne dust, high humidity, and temperature swings typical of West African mining zones.
Low Maintenance, High Uptime
With simplified oil inspection ports and robust internal construction, the units require minimal servicing—critical for sites with limited electrical personnel.
A Trusted Solution for Resource Projects
By delivering 80 fully compliant, field-ready units on schedule, TSTY supported uninterrupted commissioning of the mine’s power backbone—demonstrating how tailored design can drive operational continuity in demanding industrial environments.
