Product Description
Oil Immersed Series Transformer:
The S11-M series of fully sealed oil immersed power transformers, masterfully crafted by Zhejiang Chaotai Power, are designed to deliver exceptional benefits: low loss, minimal noise, and outstanding efficiency. These transformers not only promise significant energy savings but also contribute to reducing environmental pollution. In a stride beyond traditional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The ingeniously designed corrugated oil tank automatically adjusts and compensates changes in oil volume, thanks to its elastic corrugated sheets. By being air-tight, this innovative transformer curtails oil deterioration and insulation aging, thereby boosting operational reliability and eliminating the need for maintenance under normal operating conditions.

Our fully sealed oil immersed power transformers, a hallmark of Chaotai Power's innovation, offer unrivaled low loss, low noise, and high efficiency. They stand out for their remarkable energy-saving capabilities and pollution reduction.
Setting a new benchmark against conventional oil immersed transformers, our fully sealed design eliminates the oil conservator. The elasticity of the corrugated sheets in the oil tank autonomously adjusts to oil volume changes, ensuring the transformer is shielded from air exposure. This design innovation not only prevents oil degradation and insulation aging but also enhances operational reliability, negating the need for maintenance during normal conditions.
