Product Highlights & Applications of Oil-Immersion Distribution Transformer
High-Voltage System Adaptability:
Built for 33kV systems, the distribution transformer's reinforced winding and insulation ensure stable power delivery in heavy-load scenarios, such as industrial parks or substations. It is also ideal for rural electrification and urban grid expansion.
Energy Efficiency & Savings:
Equipped with energy-saving silicon steel cores and optimized oil-cooling systems in oil immersed distribution transformers, it reduces no-load losses by 20% and achieves 98.5% full-load efficiency. Ideal for data centers, factories, and 24/7 operations, it lowers long-term operational costs.
Harsh-Environment Resilience:
The corrosion-resistant casing and temperature-tolerant insulation oil in oil filled distribution transformers ensure stable operation between -30°C to 50°C. Perfect for coastal regions, mining sites, or industrial zones with corrosive or extreme temperatures.
Low Noise & Space-Friendly:
With noise levels under 50dB and a compact profile, this transformer suits noise-sensitive areas like commercial complexes, hospitals, or spaces with tight installation constraints.
