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
Key Features
  • Three-phase power distribution system compatibility
  • 35KV voltage rating for high-voltage applications
  • Oil-immersed cooling system for optimal thermal management
  • Variable voltage output capabilities
  • Available in 1000KVA and 1600KVA capacity options
  • Robust construction for industrial environments
  • Efficient power transformation with minimal losses
