Product Description
Oil Immersed Series Transformer:
The S11-M series fully sealed oil-immersed power transformer, innovatively developed and manufactured by Chaotai Power, stands out with its exceptional features of low loss, minimal noise, and superior efficiency. These characteristics collectively contribute to an outstanding energy-saving performance while also significantly reducing environmental impact. Unlike traditional oil-immersed transformers, this fully sealed design eliminates the need for an oil conservator. It employs an ingenious system where the fluctuating oil volume is seamlessly adjusted and compensated by the elasticity of the corrugated sheet within the corrugated oil tank. This design ensures the transformer remains isolated from atmospheric exposure, effectively preventing and decelerating oil deterioration and insulation aging, thereby enhancing operational reliability and eliminating the need for regular maintenance under normal operating conditions.
1. Power Capacity: Ranging from 25 to 2500 KVA, options include 24KV, 30KV, 33KV, 35KV, 36KV, and can be customized according to customer requirements.
4. Tapping Range: Adjustable at ±5 %, 2x2.5 %, and ±4x2.5 % for precise control.
5. Frequency: Available in two standard options, 50Hz or 60Hz.
6. Phases: Configurable as either three-phase or single-phase to suit various applications.
7. Connection Symbol: Options include Dyn11 and Yyn0, with the flexibility for other configurations upon request.
8. Short-Circuit Impedance: Designed to align with standard impedance requirements for reliable performance.
9. Altitude and Temperature Conditions: Suitable for altitudes not exceeding 1000m, with ambient temperatures not surpassing 40°C.
If conditions exceed these limits, parameter adjustments will be made to adhere to standard specifications.
Power Capacity: Offering a comprehensive range from 25 to 2500KVA.

Type of Voltage Regulation: Available in both Off-Circuit and On-Load options for diverse operational needs.
Tapping Range: Configurable at ±5%, with finer adjustments at ±2x2.5% and ±4x2.5%.
Frequency: Supports both 50Hz and 60Hz to align with international standards.
Phases: Options include both three-phase and single-phase setups.
Connection Symbol: Standard options are Dyn11 and Yyn0, with customized configurations available upon request.
Short-Circuit Impedance: Conforms to standard impedance benchmarks.
Altitude and Temperature: Designed for altitudes below 1000m and ambient temperatures not exceeding 40°C.
Adjustments to parameters will be executed as necessary to fulfill standard compliance if these conditions are not met.
The fully sealed oil-immersed power transformer, a product of Chaotai Power, excels with low loss, reduced noise, and enhanced efficiency, ensuring optimal energy savings and minimal pollution.
Distinct from conventional oil-immersed transformers, the fully sealed variant forgoes the oil conservator. It ingeniously manages oil volume changes via the corrugated sheet's elasticity in the oil tank, keeping the transformer air-sealed. This design effectively prevents oil degradation and insulation wear, boosts operational dependability, and eliminates the need for routine maintenance in normal conditions.
