Product Description
Oil Immersed Series Transformer:
Introducing Zhejiang Chaotai's S11-M series, a state-of-the-art fully sealed oil immersed power transformer. Our product boasts remarkable features such as minimized loss, reduced noise levels, and unparalleled efficiency, delivering significant energy savings and cutting down environmental pollution. Unlike ordinary transformers, our design eliminates the need for an oil conservator. Instead, the innovative elasticity of the corrugated oil tank compensates for oil volume fluctuations. This ensures isolation from air, which in turn prevents oil degradation and insulation aging, leading to enhanced reliability and maintenance-free operation.

Voltage Level:
Type of Voltage Regulation: Choose between Off-circuit and On-load options.
Tapping Range: Adjustable to ±5%, 2x2.5%, and ±4x2.5% for precision.
Frequency: Supports both 50Hz and 60Hz operation.
Phases: Available in adaptable three-phase or single-phase options.
Connection Symbol: Options include Dyn11, Yyn0, or tailored configurations as requested.
Short-circuit Impedance: Conforms to standard impedance norms.
Altitude and Temperature: Designed to perform optimally at altitudes below 1000m and temperatures not exceeding 40°C.
For environments that deviate from these conditions, parameters can be tailored to align with industry standards.
The fully sealed oil immersed power transformer by Chaotai Power delivers minimal loss, low noise, and superior efficiency, ensuring energy savings and reduced pollution.
Our fully sealed transformer, a leap beyond ordinary designs, eliminates the oil conservator. Oil volume variation is managed automatically by the corrugated tank's elasticity, isolating the transformer from air to prevent oil degradation and insulation aging. This results in enhanced operational reliability and maintenance-free performance.
