1. Core Challenges in African Manufacturing Plants​1 ​Unstable Power Supply​Aging grids and insufficient generation capacity plague African nations. For instance, South Africa's 2023 power deficit caused 5%-10% GDP loss, while 97% of Nigerian factories rely on expensive diesel generators (annual fuel costs: $14 billion). Frequent outages disrupt production continuity and damage equipment.1.2​Weak Infrastructure​Remote areas lack transmission networks, and traditional substations require 3–

1.Project Background and Market Opportunities​​1.1 Surge in Russia’s Power Demand​Russia’s urbanization and new residential/industrial zones demand stable power supply. Prefabricated substations, with their modularity and rapid deployment, are critical. By 2025, Russia’s power infrastructure investment is projected to exceed RUB 200 billion, with prefabricated substations accounting for over 40%.​Renewable Energy Drivers: Rising grid integration needs for wind/solar energy requ

1. Challenges1.1 Insufficient Adaptability to Bidirectional Power FlowVoltage Fluctuation & Overload RisksBidirectional power flow exacerbates voltage instability and equipment overload, endangering transformers and grid integrity. Enhanced adaptive design is imperative.Unidirectional Design LimitationsConventional 10 kV distribution transformers, designed for unidirectional power flow, struggle to accommodate distributed generation integration in microgrids.Power Quality & Equipment Lon

1. The Challenges Faced1.1 Complex Electromagnetic Interference SourcesDiverse Types of Electromagnetic InterferenceIn 10kV distribution systems, power electronic equipment, switching operations, lightning strikes, and other factors generate high-frequency and pulsed electromagnetic interference. These interference signals act on distribution transformers through conduction or radiation, compromising their normal operation.Risk of Transformer DamageExcessive electromagnetic interference may lead

1.Introduction1.1 Urgent Need for Upgrading Distribution TransformersRising Load DensityDuring peak hours, transformers often operate overloaded, raising temperatures (by 15–25°C in extreme cases). Prolonged heat speeds up insulation degradation (like in paper-oil systems), boosting failure risks—overloaded units have up to 40% higher failure rates.Power Quality DisturbancesVoltage fluctuations > ±10% of nominal values disrupt sensitive gear (medical devices, data cente
