Product Description
Oil Immersed Series Transformer - Engineered with cutting-edge technology, our transformer series represents a leap forward in power transformation solutions.
The S11-M series fully sealed oil immersed power transformer, crafted by Chaotai Power, offers exceptional benefits including significantly reduced loss, whisper-quiet operation, and outstanding efficiency. This state-of-the-art equipment promises not only an impressive energy-saving performance but also contributes to pollution reduction. Unlike traditional transformers, our fully sealed design eliminates the oil conservator, with oil volume changes automatically adapted through the innovative corrugated oil tank. Isolation from air ensures the longevity of the oil and insulation by hindering deterioration and aging, thus enhancing reliability and eliminating the need for maintenance during regular operation.

Short-Circuit Impedance: Built to comply with industry-standard impedance guidelines, delivering consistent performance.
Altitude and Temperature: Suitable for altitudes up to 1000m and ambient temperatures up to 40°C, with customizable solutions for unique conditions.
For situations that deviate from these criteria, we ensure parameter adjustments in accordance with international standards to maintain functionality and efficiency.
Our fully sealed oil immersed power transformer, pioneered by Chaotai Power, is distinguished by its minimal loss, low noise, and high efficiency, setting new benchmarks in energy conservation and environmental responsibility.
In contrast to conventional oil-immersed transformers, our fully sealed model eradicates the need for an oil conservator. The flexible corrugated oil tank autonomously adjusts to oil volume changes, ensuring isolation from air and significantly decelerating oil degradation and insulation aging. This design boosts operational reliability and minimizes the necessity for maintenance under standard operating conditions.
