Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, a groundbreaking innovation by Zhejiang Chaotai Power, is engineered for outstanding performance. Designed with the advantages of low loss, low noise, and high efficiency, it delivers remarkable energy-saving benefits while significantly minimizing environmental impact. Unlike conventional oil-immersed transformers, this state-of-the-art model eliminates the need for an oil conservator by utilizing a flexible corrugated oil tank. This ingenious feature allows for automatic volume adjustments and compensations, ensuring the transformer remains isolated from air exposure. By preventing oil deterioration and slowing insulation aging, operational reliability is enhanced, reducing the need for maintenance during regular operations.

Operational Parameters: Designed for altitudes up to 1000m and ambient temperatures up to 40°C. Custom adjustments available for non-standard conditions.
If operational conditions exceed standard limitations, parameter modulation will be executed for maintained compliance.
Chaotai Power's fully sealed oil-immersed power transformer is crafted with superior attributes such as low loss, minimal noise, and high efficiency. It provides an excellent energy-saving solution while reducing environmental impact.
In comparison to standard oil-immersed transformers, this advanced fully sealed model negates the oil conservator and utilizes a corrugated oil tank for autonomous volume adjustment through its elasticity. This design isolates the transformer from air exposure, preventing oil degradation and slowing insulation aging. It boosts operational reliability and minimizes maintenance requirements under regular conditions.
