Product Description
Oil Immersed Series Transformer:
The S11-M series by Chaotai Power, a fully sealed oil-immersed power transformer, sets new standards in energy efficiency and eco-conscious design. Offering notable features such as low loss, minimized noise, and high operational efficiency, this transformer excels in delivering substantial energy savings while also lessening environmental impact. Its innovative design eliminates the conventional oil conservator, allowing the oil volume adjustments to be seamlessly managed by the corrugated sheet's flexibility in the oil tank. By being impeccably isolated from air, it effectively prolongs the life of the oil and insulation, boosting reliability and eliminating the need for maintenance during regular operation.

The fully sealed oil-immersed power transformers by Chaotai Power are lauded for their superior low-loss and noise-reduction capabilities paired with exceptional operational efficiency. These transformers not only promise significant energy conservation but also strive to minimise environmental pollution.
Standing out among oil-immersed transformers, the fully sealed variant eliminates the need for an oil conservator. It intelligently regulates oil volume adjustments using the elasticity of its corrugated oil tank sheets. This design ensures the transformer is isolated from the air, effectively curbing oil deterioration and insulation aging, thereby enhancing operational reliability and negating the need for maintenance during standard operations.
