Tanaka Electric
Engineered for immediate integration into municipal grids and local heavy industry in Banfora.
Banfora, located strategically within the Cascades Region, serves as a vital economic engine for Burkina Faso. Known for its vast agricultural reserves, it houses crucial industrial facilities such as the SN SOSUCO sugar refinery, massive cotton-ginning plants, and flour mills. These agro-industries rely heavily on stable electrical infrastructure to power high-torque machinery, heavy compressors, and automated refining plants.
However, the local electrical distribution system faces distinct environmental and grid challenges. Operating under the SONABEL network and local regional grids, electrical infrastructure must withstand ambient temperatures often peaking above 40°C during the dry season, heavy seasonal rainfall, and high atmospheric dust (harmattan winds). Standard transformers fail prematurely under these harsh operating parameters due to thermal breakdown and dust accumulation in the cooling ducts.
To support this regional development, Tanaka Electric provides specially built step-down distribution transformers designed to step down high line voltage (typically 33kV, 15kV, or 11kV) down to the standard industrial operating voltage of 400V/230V, securing continuous runtime for local mills, refineries, and expanding municipal grids.
Standard design rating up to 45°C ambient temperature with optimal ONAN/ONAF cooling configurations to prevent thermal derating.
Completely sealed oil-immersed configurations (hermetically sealed) prevent dust particles and humidity from contaminating the insulating oil.
Designed to absorb and cushion voltage fluctuations common in the West African Power Pool (WAPP) transit networks.
How our advanced factory capabilities in China deliver superior electrical efficiency, thermal resilience, and custom build properties directly to West Africa.
We utilize premium Cold Rolled Grain Oriented (CRGO) silicon steel and Amorphous Alloy cores. This dramatically reduces no-load losses, ensuring that rural grids in Banfora do not waste precious generation capacity when operating under minimal load conditions.
Our factory operates state-of-the-art CNC automatic winding machines and automatic foil winding systems. This guarantees maximum physical symmetry and density in the coils, enhancing short-circuit withstand capabilities during rapid grid faults.
For dry-type transformers, we use CNC static vacuum casting to eliminate internal micro-voids in the epoxy resin. This prevents partial discharges (PD) under high voltage stress, radically extending the life cycle of the transformer.
Tanaka Electric designs and manufactures transformers adhering strictly to international standards compatible with CE, IEC, CCC, ISO9001, and UL guidelines.

Every industrial node has its own unique electrical blueprint. Our engineers specialize in mapping out solutions that sit at the intersection of local grid variables and device loads:
Sugarcane crushing, milling, and distillation require massive electric motors. Standard starters create voltage drops. Our step-down solutions feature high temporary overcurrent capabilities (overload tolerance) to manage the massive start-up torque requirements of sugar factories.
Burkina Faso is aggressively expanding its utility-scale solar installations. Our step-down and step-up dual-purpose pad-mounted transformers operate perfectly with grid inverter networks, managing bidirectional power flows and high-frequency harmonics seamlessly.
Zhejiang Tanaka Electric has established a robust maritime and overland supply route serving West Africa. For projects in Banfora, we manage complete export compliance from Shanghai or Ningbo ports to the primary destination ports of Abidjan (Côte d'Ivoire) or Tema (Ghana).
From the ocean terminals, transformers are safely transported overland via secure transit corridors directly to your project site in the Cascades region. We provide specialized impact recorders on our larger units (like the 1250kVA-10MVA classes) to ensure that the core structures remain mechanically intact and unshifted throughout the entire voyage.

Answers to crucial engineering and logistical questions regarding transformer imports and installations in Burkina Faso.
For outdoor industrial or utility installations in Banfora, we recommend oil-immersed transformers. The hermetically sealed oil design offers exceptional self-cooling (ONAN) and protects internal windings from sand dust (harmattan), high humidity during the rainy season, and ambient temperature spikes. For indoor industrial substations, high-rise buildings, or sugar factory control rooms where fire hazard mitigation is critical, we recommend our epoxy-cast dry-type transformers (Class H insulation).
Our transformers are engineered with a high Basic Impulse Level (BIL) of up to 170kV (depending on voltage ratings). We reinforce the insulation systems of the first few turns of the primary windings, which receive the brunt of high-frequency atmospheric surges. Additionally, we integrate high-durability zinc-oxide lightning arresters to clamp voltage surges safely to the ground before they penetrate the winding coils.
We provide full customization of primary and secondary ratings. Whether you are interfacing with a 33kV high-voltage trunk, a regional 15kV/11kV network, or need specialized local outputs like 400V, 230V, or isolated 110V/12V for PLC control circuits, our engineering team will design a winding layout matching your specific single-phase or three-phase configurations.
Every unit leaving the Tanaka Electric facility undergoes rigorous testing, including ratio tests, polarity tests, winding resistance measurements, insulation resistance testing (megger test), no-load loss and load loss measurements, and high-pot (dielectric) tests. Customers may request third-party inspections (such as SGS or Bureau Veritas) before loading, which we welcome and coordinate.
Heavy electrical equipment is vulnerable to micro-movements during long-distance transit. We secure the internal cores of our transformers with reinforced tension rods and heavy steel structures. Oil-immersed units are shipped with special anti-slosh baffles in the conservator tanks and securely braced inside custom timber and steel shipping frameworks. For sensitive utility orders, we embed G-force data loggers on the chassis to monitor transport conditions from China to the final substation pad in Banfora.
