Large livestock farms in Africa require a stable and reliable power supply for poultry houses, dairy facilities, feed mills, water pumping systems, ventilation, lighting, refrigeration and automated feeding equipment. A properly sized oil-immersed distribution transformer provides efficient medium-voltage power distribution for continuous farm operations.
1. Typical Farm Power System
A typical large livestock farm can use:
MV Grid 11kV/22kV/33kV → Distribution Transformer → LV Switchgear → Farm Distribution Network
The transformer steps down medium voltage to commonly used low-voltage systems such as 400V/230V, supplying different production and auxiliary areas.
2. Main Applications
- Poultry Houses – ventilation fans, lighting, automatic feeding and temperature-control systems
- Dairy Farms – milking machines, cooling tanks, ventilation and water pumps
- Feed Mills – crushers, mixers, conveyors and grain processing equipment
- Water Supply Systems – borehole pumps, irrigation and water treatment
- Cold Storage – refrigeration and agricultural product preservation
- Farm Buildings – offices, worker accommodation, warehouses and workshops
3. Recommended Transformer Configuration
For large commercial farms, three-phase oil-immersed distribution transformers are commonly suitable because of their reliable operation, strong overload capability and outdoor installation flexibility.
Typical configuration:
Capacity: 100kVA–2500kVA
Primary Voltage: 11kV / 22kV / 33kV
Secondary Voltage: 400V / 415V
Frequency: 50Hz
Cooling: ONAN
Installation: Outdoor / Pole-Mounted / Ground-Mounted
Standard: IEC 60076
The final transformer capacity should be determined according to the farm's total connected load, motor starting current, future expansion and required load factor.
4. Why Choose New Electric Power?
For African livestock projects, New Electric Power can customize transformer capacity, voltage ratio, impedance, enclosure, protection configuration and installation method according to local grid conditions and farm requirements.
