Product Description
Introducing Our Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, a cutting-edge development by Chaotai Power, boasts exceptional low-loss performance, minimal noise, and extraordinary efficiency. This transformative device not only conserves energy but also minimizes environmental pollution. Unlike conventional oil-immersed transformers, our fully sealed model eliminates the need for an oil conservator. The volumetric changes in oil are adeptly managed through the corrugated oil tank's resilient elasticity. This innovative design ensures the transformer is shielded from air exposure, significantly reducing oil degradation and insulation wear, thus greatly enhancing operational reliability and obviating the need for routine maintenance.
1. Power Capacity: Our transformers range from 25-2500KVA, with voltage options of 24KV, 30KV, 33KV, 35KV, 36KV, and customizable specifications to meet customer needs. 2. Voltage Level: Options include 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, and 22KV. 3. Voltage Regulation: Choose between Off-circuit or On-load regulation.
4. Tapping Range: Options include ±5%, 2x2.5%, or ±4x2.5% adjustments for precise performance control.
5. Frequency: Available for either 50Hz or 60Hz operations.
6. Phases: Available in both three-phase and single-phase models.
7. Connection Symbol: Options include Dyn11 and Yyn0, with customizable configurations upon request.
8. Short-Circuit Impedance: Standard impedance ensures reliable operation.
Altitude must be at or below 1000m, and ambient temperatures should not exceed 40°C. If these conditions are not met, modifications will be made accordingly.
We will tailor parameters in line with industry standards.

Our fully sealed oil immersed power transformer, crafted by Chaotai Power, presents significant advantages including reduced loss, minimized noise, and superior efficiency, resulting in excellent energy conservation and pollution reduction.
The innovative fully sealed transformer sets itself apart from standard oil-immersed options by eliminating the oil conservator. Oil volume changes are seamlessly managed by the corrugated oil tank's elasticity, ensuring the device remains isolated from air exposure. This prevents oil degradation and insulation aging, greatly enhancing reliability and eliminating the need for standard operational maintenance.
