Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, innovatively developed and manufactured by Chaotai Power, boasts exceptional features such as low loss, minimal noise, and outstanding efficiency. This leads to remarkable energy savings and reduced pollution. Unlike conventional oil immersed transformers, our fully sealed design eliminates the need for an oil conservator. The oil volume changes are smoothly managed and adjusted by the corrugated sheet's elasticity within the corrugated oil tank, which is ingeniously isolated from the air. This unique feature prevents and slows down oil deterioration and insulation aging, significantly enhancing operational reliability and eliminating the need for maintenance during normal operation.
1. Power Capacity: Ranges from 25 to 2500 KVA, available in 24KV, 30KV, 33KV, 35KV, 36KV, and customizable options according to customer requirements. 2. Voltage Level: Available in 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV.
4. Tapping Range: Offers flexibility with ±5%, 2x2.5%, and ±4x2.5% adjustment options.
5. Frequency: Compatible with both 50Hz and 60Hz.
6. Phases: Available in either three-phase or single-phase configurations.
7. Connection Symbol: Configurations include Dyn11, Yyn0, or as per specific requests.
8. Short-Circuit Impedance: Adheres to standard impedance specifications.
Altitude should not exceed 1000 meters, with ambient temperature remaining below 40°C. If conditions differ, we adjust parameters according to industry standards.
Parameter adjustments will be made in alignment with standard specifications if such conditions are not met.

Tapping Range: Options include ±5%, ±2x2.5%, and ±4x2.5% for versatile adjustment.
Frequency: Designed to operate at either 50Hz or 60Hz.
Phases: Available in three-phase or single-phase systems.
Connection Symbol: Standard configurations are Dyn11 and Yyn0, with custom options available.
Short-Circuit Impedance: Conforms to standard impedance guidelines.
Ensure altitude does not exceed 1000m, and ambient temperature remains below 40°C.
For conditions not meeting these standards, we will adjust parameters as per industry norms.
Chaotai Power's fully sealed oil immersed power transformer stands out with its superior qualities of low loss, low noise, and high efficiency, ensuring significant energy savings and reduced environmental impact.
In comparison to traditional oil immersed transformers, our fully sealed design eliminates the oil conservator. The oil volume's natural adjustment is achieved through the corrugated oil tank's elasticity, keeping the transformer isolated from air. This unique feature prevents oil degradation and insulation aging, thereby boosting operational reliability and eliminating maintenance needs during normal operation.
