Oil Immersed Series Transformer
The fully sealed oil-immersed power transformer series features low loss, low noise, and high efficiency, achieving excellent energy-saving effects and reduced pollution. Unlike standard transformers, this fully sealed design eliminates the oil conservator. Changes in oil volume are automatically adjusted and compensated for by the elasticity of the corrugated oil tank sheets. The system is isolated from the air, preventing oil deterioration and insulation aging, which enhances reliability and eliminates the need for maintenance during normal operation.
