Product Description
Oil Immersed Series Transformer:
The S11-M series of fully sealed oil-immersed power transformers, meticulously crafted by Chaotai Power, stand as paragons of efficiency and eco-friendliness. These transformers boast low loss, minimal noise, and superior operational efficiency, delivering remarkable energy savings while significantly curtailing pollution. Unlike conventional oil-immersed transformers, this fully sealed design eliminates the need for an oil conservator. Ingeniously, it adjusts and compensates changes in oil volume through the elasticity of corrugated sheets in the oil tank, ensuring the unit remains isolated from air exposure. This design innovation not only slows oil and insulation degradation but also heightens operational reliability and negates the need for routine maintenance.
1. Power Capacity: A robust range of 25-2500KVA, accommodating voltages of 24KV, 30KV, 33KV, 35KV, and 36KV, with customization available per customer specifications.
4. Tapping Range: Offers precision with ±5%, ±2x2.5%, ±4x2.5% options.
5. Frequency: Adaptable for both standard frequencies of 50Hz and 60Hz.
6. Phases: Configurable for either three-phase or single-phase systems.
7. Connection Symbol: Flexibility in connection options, including Dyn11 and Yyn0, or customizable as per request.
8. Short-Circuit Impedance: Designed with standard impedance for optimal performance.
9. Altitude and Temperature: Engineered to perform optimally at altitudes up to 1000m and temperatures not exceeding 40°C. Should these conditions vary, our parameters will be adjusted to adhere to standard requirements.
In accordance with industry standards, adjustments ensure peak performance under varying conditions.
Power capacity: Ranging from a substantial 25-2500KVA.
Voltage Level Options: Catering to 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, and 22KV requirements.
Voltage Level:
Type of Voltage Regulation: Options available for off-circuit or on-load configurations.
Tapping Range: Allows for fine-tuning with ±5%, ±2x2.5%, ±4x2.5%.
Frequency: Compatible with both 50Hz and 60Hz.
Phases: Available in both three-phase and single-phase configurations.
Connection Symbol: Options include Dyn11 and Yyn0, with further customization available upon request.
Short-Circuit Impedance: Built to meet standard impedance specifications.
Altitude and Temperature: Suitable for altitudes up to 1000m and ambient temperatures below 40°C.
Should environmental conditions fall outside these parameters, we ensure compliance through parameter adjustments in line with industry standards.
Chaotai Power's fully sealed oil-immersed transformers are designed to minimize loss, reduce noise, and maximize efficiency, resulting in substantial energy savings and pollutant reduction.
This advanced design supersedes conventional models by eliminating the oil conservator and utilizing a flexible corrugated sheet to self-regulate oil volume changes. This feature isolates the transformer from air exposure, effectively slowing oil degradation and insulation aging, boosting operational reliability, and obviating the need for regular maintenance.
