Product Description
Oil Immersed Series Transformer:
Introducing the S11-M series fully sealed oil immersed power transformer, meticulously developed and crafted by Chaotai Power. This innovative transformer is distinguished by its exceptional attributes of low loss, minimal noise, and superior efficiency. With its remarkable energy-saving capabilities, it significantly reduces pollution. Unlike conventional oil immersed transformers, this fully sealed model eliminates the need for an oil conservator. Instead, it smartly adjusts and compensates for changes in oil volume through the flexible corrugated sheet design of its corrugated oil tank. This design ensures the transformer is shielded from air exposure, thereby preventing oil deterioration and insulation aging. Its operation reliability is enhanced, and it is engineered to be maintenance-free under normal operation.
1. Power Capacity: Spanning a range of 25-2500KVA, this transformer accommodates various voltage requirements including 24KV, 30KV, 33KV, 35KV, 36KV, and customizable options according to customer specifications. 2. Voltage Level: Offers a comprehensive choice from 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, to 22KV. 3. Type of Voltage Regulation: Flexibility with Off-circuit or On-load regulation.
4. Tapping Range: Precisely adjustable with options of ±5%, ±2x2.5%, ±4x2.5% to fine-tune performance.
5. Frequency: Operates seamlessly at either 50Hz or 60Hz.
6. Phases: Available in both three-phase or single-phase configurations to suit varied needs.
7. Connection Symbol: Versatile with options such as Dyn11, Yyn0, or tailored as per request.
8. Short-circuit Impedance: Adheres to the Standard Impedance for optimal performance.
9. Altitude is designed for operation not exceeding 1000m, while ensuring ambient temperatures remain within 40°C.
If these conditions are not met, parameters will be modulated in accordance with the standard.
