Product Description
Three Phase Power Transformer Overview
Our 35kV oil-immersed power transformers (1000kVA / 1600kVA) are specially designed and validated for tropical and high-temperature regions, making them ideal for Africa and Latin America, where ambient temperatures, humidity, dust, and grid instability present significant operational challenges.
High Ambient Temperature Performance
- Designed for ambient temperatures up to 45°C (optional design up to 50°C)
- Enhanced thermal margin ensures stable operation under continuous heavy load conditions
- Optimized oil circulation and radiator design improve heat dissipation in hot climates
Tropicalized Insulation System
- High-quality mineral insulating oil with excellent oxidation resistance
- Upgraded insulation materials with Class A / thermal-optimized design
- Increased creepage distance to prevent insulation aging in hot and humid environments
High Humidity & Dust Protection
- Suitable for high humidity (>95%) and dusty environments common in mining and rural grid areas
- Sealed or conservator-type oil tank options reduce moisture ingress
- Breather equipped with silica gel dehydrator for effective moisture control
Grid Instability & Voltage Fluctuation Adaptation
- Strong tolerance to frequent voltage fluctuations and unstable grid conditions
- Optional On-Load Tap Changer (OLTC) allows real-time voltage regulation without shutdown
- Reinforced winding structure improves short-circuit withstand capability in weak grids
Anti-Corrosion & Outdoor Durability
- Multi-layer anti-corrosion coating suitable for coastal, tropical, and industrial pollution areas
- Optional C4 / C5 anti-corrosion protection for high-salinity or coastal regions
- Designed for long-term outdoor installation with minimal maintenance
