Project Background​Ethiopia, located in the East African plateau, has an average altitude exceeding 3,000 meters. In some areas, winter temperatures can drop to -30°C, accompanied by significant diurnal temperature variations (up to 25°C daily) and intense ultraviolet radiation. The local power system faces the following challenges:​SF6 Gas Liquefaction Risk: Traditional Dead Tank SF6 Circuit Breakers are prone to SF6 gas liquefaction at low temperatures (critical liquefaction temperatur

1.Challenges Faced by Wind Farms1.1​ Extreme Environmental Conditions​Wind farms are often located in coastal, high-altitude, or desert areas with harsh conditions such as high salt spray, UV radiation, and temperature fluctuations (-40°C to +60°C). Traditional circuit breakers are prone to corrosion and insulation degradation, leading to reduced lifespan and increased failure rates.1.2 Current Fluctuations and Grid Stability Issues​The intermittent nature of wind power causes frequent s

1.Core Challenges in Africa's Solar Power Development​1.​1 Weak Grid Infrastructure​Low grid coverage in remote areas, aging transmission/distribution systems, and limited capacity for large-scale solar integration.1.2 ​Environmental Adaptability Issues​Extreme conditions (e.g., high temperatures, sandstorms, humidity in Kenya’s Garissa region) accelerate equipment corrosion and insulation degradation.​1.3 Insufficient Maintenance Capabilities​Lack of skilled technicians and stable mainten

1.Project Background and Demand Analysis​​1.1 Saudi Distribution Network Upgrade Requirements​Saudi Arabia is advancing its "Vision 2030" energy transition plan, aiming to achieve ​40% distribution network automation by 2025​. Key initiatives include deploying ​33,000 intelligent ring main units (RMUs) and reclosers​ in 11 cities like Riyadh and Dammam to enhance grid reliability and renewable energy integration.
