Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, a hallmark of Chaotai Power, stands out with its exceptional low-loss and low-noise performance. This high-efficiency marvel not only elevates energy conservation but also plays a pivotal role in minimizing environmental pollution. In a significant leap from conventional oil-immersed transformers, this advanced model eliminates the oil conservator. Instead, it showcases an innovative design where oil volume is deftly adjusted and compensated through the elasticity of the corrugated sheet within the corrugated oil tank. This design ensures the transformer remains sealed from external air, effectively preventing oil deterioration and insulation degradation. The result is a transformer that promises robust operational reliability and negates the need for maintenance under normal conditions.

Connection Symbol: Customizable to Dyn11, Yyn0, or other requested configurations.
Short-Circuit Impedance: Designed to meet standard impedance requirements.
Operates efficiently at altitudes not exceeding 1000m, withstanding ambient temperatures up to 40°C.
In cases where installation conditions deviate from the norm, our transformers are adjustable to meet standard industry parameters.
The fully sealed oil-immersed power transformer from Chaotai Power is an exemplar of innovation, offering low loss, low noise, and remarkable efficiency. It significantly contributes to energy conservation while reducing pollution.
When compared to traditional oil-immersed transformers, our fully sealed design eliminates the oil conservator, with oil volume changes automatically managed by the corrugated sheet's elasticity within the oil tank. This isolation from air not only slows oil and insulation degradation but also enhances operational reliability, negating the need for routine maintenance.
