Product Description
Oil Immersed Series Transformer:
The S11-M series, crafted with precision by Chaotai Power, presents a fully sealed oil-immersed transformer designed to excel. Boasting significant advantages like low loss, minimal noise, and heightened efficiency, it delivers exceptional energy-saving capabilities while minimizing environmental impact. Unlike ordinary transformers, this advanced model eliminates the need for an oil conservator. The oil volume is ingeniously stabilized through the flexible corrugated sheets of the oil tank, providing automatic adjustment and compensation. By being isolated from external air, the transformer ensures prolonged oil purity and insulation integrity, enhancing operational reliability and minimizing maintenance needs under standard conditions.
1. Power Capacity: From 25 to 2500 KVA, adaptable with 24KV, 30KV, 33KV, 35KV, 36KV, and customizable as per customer requirements. 2. Voltage Level: Available in 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV variations. 3. Type of Voltage Regulation: Options for Off-circuit or On-load regulation.
4. Tapping Range: Options include ±5%, ±2x2.5%, or ±4x2.5%.
5. Frequency: Designed to operate seamlessly at 50Hz or 60Hz.
6. Phases: Available in both Three-phase or Single-phase configurations.
7. Connection Symbol: Flexible configurations with Dyn11, Yyn0, or customized options as requested.
8. Short-circuit Impedance: Adheres to standard impedance parameters.
The transformer is engineered for altitudes not exceeding 1000m and ambient temperatures not surpassing 40°C. lf these conditions cannot be met, we will adjust parameters to adhere to the standard.
Modifications in accordance with the prevailing standard will ensure optimal performance.
Power Capacity: Ranging impressively from 25 to 2500KVA.
Voltage Options: IOkV, 11kV, 13.8kV, 15kV, 17.5kV, 20kV, 22kV, 30kV, 33kV, 35kV, 36kV.
Voltage Level: Tailored to meet specific application needs.
Type of Voltage Regulation: Choose between Off-circuit or On-load adjustments.
Tapping Range: Customize with ±5%, ±2x2.5%, or ±4x2.5% settings.
Frequency: Compatible with both 50Hz and 60Hz power frameworks.
Phases: Options for Three-phase or Single-phase systems.
Connection Symbol: Configurable as Dyn11, Yyn0, or as specified by the user.
Short-circuit Impedance: Maintains standard impedance for optimal function.
Designed for altitudes below 1000m and ambient temperatures under 40°C.
Should conditions exceed these parameters, customized modulation will align with standards.
Crafted with precision, the fully sealed oil-immersed power transformer by Chaotai Power embodies low loss, serene quietness, and supreme efficiency, promoting energy savings and reducing environmental impact.
In contrast to conventional models, our innovative fully sealed transformer removes the need for an oil conservator. The oil volume is adeptly managed by the elasticity of the corrugated oil tank sheets, ensuring automatic adjustment and compensation. This design isolates the transformer from the air, thereby preventing oil degradation and insulation aging, enhancing operational reliability, and minimizing maintenance during regular use.
