YAWEI CASE
As one of the fastest-growing economies in Africa, Rwanda has been committed to achieving "universal electrification" and a green energy transition in recent years by actively promoting the construction of energy infrastructure. However, the country still faces challenges such as low grid coverage, insufficient power supply stability and limited integration capacity of renewable energy. Against this background, YAWEI Power Transformers, with its high cost performance, environmental adaptability and intelligent design, have become one of the key solutions for power engineering projects in Rwanda.
In response to Rwanda's complex geographical environment and energy demands, Yawei transformers have carried out targeted optimizations in design and functionality:
High altitude and rainy environment: Rwanda has an average altitude of over 1,500 meters, with concentrated precipitation during the rainy season. Yawei transformers adopt special insulating materials for high altitudes (such as C-class insulation systems) and moisture-proof sealing structures (protection grade IP55) to ensure stable operation under humid and hot conditions as well as low air pressure.
Seismic and shock-resistant design: In response to the geological activities in the Great Rift Valley region of East Africa, the box adopts reinforced steel structure and has passed the IEC 60076-11 seismic certification to reduce the risk of equipment damage caused by geological disasters.
It adopts a fully sealed oil-immersed design, eliminating the need for frequent replacement of insulating oil and reducing operation and maintenance requirements. It is suitable for the current situation of insufficient technical manpower in remote areas of Rwanda.
The use of corrosion-resistant coated steel plates and silicone rubber seals can extend the service life of the equipment (with a design life of over 25 years) and reduce the total life cycle cost.
Supports direct connection of photovoltaic/wind power on the low-voltage side, with a wide voltage regulation range of ±5%, suitable for the fluctuating power generation of small hydropower stations and off-grid solar systems in Rwanda.
Integrate intelligent grid connection interfaces that comply with the standards of the East African Community (EAC) to ensure interconnection and interoperability with the regional power grid.
Through customized technology, cost controllability and localized services, Yawei power transformers have been deeply integrated into Rwanda's energy transition process. They not only address the urgent needs of the country's power infrastructure, but also provide a model for the sustainable development of energy in Africa with their green and intelligent characteristics.
After replacing the energy-saving transformer, the factory's average monthly electricity consumption has dropped by about 15%. The no-load loss and load loss are significantly lower than the national standard. The electricity bill saved by long-term use is close to the equipment purchase cost, and the cost-effectiveness is outstanding.
