Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil immersed power transformer, innovatively developed and produced by Zhejiang Chaotai Complete Equipment Co., Ltd., stands out with its exceptional attributes of low loss, reduced noise, and unparalleled efficiency. These traits collectively deliver an impressive energy-saving performance while significantly curbing environmental pollution. In contrast to conventional oil immersed transformers, this state-of-the-art model eliminates the oil conservator. Instead, it cleverly utilizes the elasticity of the corrugated sheet in the corrugated oil tank to automatically adjust and compensate for oil volume changes. This sophisticated design isolates the transformer from air exposure, thereby slowing the degradation of oil and insulation aging, bolstering operational reliability, and minimizing the need for maintenance during regular operation.

Voltage Level: Offered in 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV based on requirements. 3. Type of Voltage Regulation: Options include both Off-circuit and On-load regulation.
4. Tapping Range: Configurations available at ±5%, ±2x2.5%, and ±4x2.5%.
5. Frequency: Compatible with both 50Hz and 60Hz frequencies.
6. Phases: Available in either Three-phase or single-phase configurations.
7. Connection Symbol: Configurable as Dyn11, Yyn0, or tailored as per request.
8. Short-circuit Impedance: Adheres to Standard Impedance norms.
The transformer is designed for optimal performance in ambient temperatures not exceeding 40°C. If these conditions are not met, we will adjust parameters accordingly.
Modifications will be aligned with standard protocols to ensure reliability.
Power Capacity: Range of 25-2500KVA available.
Voltage Levels include customizable configurations of 10KV, 22KV, 30KV, 33KV, 35KV, 36KV.
Voltage Level:
Voltage Regulation Type: Choice between Off-circuit and On-load regulation.
Tapping Range: Options of ±5%, ±2x2.5%, and ±4x2.5%.
Frequency Compatibility: 50Hz or 60Hz, tailored to customer needs.
Phase Options: Three-phase or single-phase configurations available.
Connection Symbols: Dyn11, Yyn0, or as specified by the customer.
Short-circuit Impedance: Conforms to Standard Impedance guidelines.
Operating conditions include an altitude not exceeding 1000m and ambient temperature below 40°C.
If such conditions are unmet, we will adjust parameters to align with established standards.
The fully sealed oil immersed power transformer from Zhejiang Chaotai Complete Equipment Co., Ltd. surpasses others with its low loss, reduced noise, and high efficiency, delivering remarkable energy-saving benefits and minimizing pollution.
By eliminating the oil conservator, the fully sealed transformer automatically adjusts oil volume changes via the corrugated oil tank's elasticity, preventing air exposure, reducing oil degradation and insulation aging, enhancing reliability, and avoiding maintenance during normal operation.
