Product Overview of 110kV (66kV) Oil Immersed Power Transformer
Our 110kVoil filled transformers are high-voltage three-phase oil-immersed power transformers designed for power distribution networks. Available in 110kV and 66kV configurations, they support 50/60Hz grids and are ideal for industrial substations, infrastructure projects, and regional power networks. Key benefits include:
Energy Efficiency: Reduces operational energy consumption through advanced core materials;
Quiet Operation: Optimized cooling and structure ensures noise levels ≤55dB (1m distance), suitable for urban installations;
Environmental Adaptability: Operates reliably between -30℃ to +50℃ and high humidity environments.
This three phase oil immersed transformer delivers a cost-effective and stable power conversion solution for new and upgraded grid systems.
Low Losses:
Advanced silicon steel cores and optimized winding design reduce no-load losses to 65% of national standards for 110kV Oil Immersed Power Transformer, lowering long-term operational costs.
Low Noise:
3D acoustic damping and structural innovations keep noise ≤55dB (1m), meeting urban environmental regulations.
110kVoil filled transformers are designed for the following environments:
Temperature: -30℃~+50℃, daily temperature fluctuation ≤25℃;
Altitude: ≤1000m (special high-altitude models up to 4000m);
Humidity: Relative humidity ≤95% (no condensation);
Installation: Requires level foundations and ventilated spaces, away from fire sources and corrosive gases;
Grid Compatibility: Supports 110kV/66kV high-voltage input and 10kV low-voltage output, optimized for balanced three-phase loads.
Proven in extreme conditions, this transformer ensures uninterrupted performance across harsh climates and complex grids.
