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 remarkable attributes of low loss, minimal noise, and exceptional efficiency. These traits collectively contribute to substantial energy savings and environmental protection. Unlike conventional oil immersed transformers, this advanced model eliminates the need for an oil conservator. Instead, it utilizes the elasticity of the corrugated sheet in the oil tank to automatically adjust and compensate for oil volume changes. By being isolated from the air, it significantly delays oil deterioration and insulation aging, thereby boosting operational reliability and negating the necessity for regular maintenance during standard operations.
1. Power Capacity: This transformer offers a versatile power capacity ranging from 25 to 2500KVA, catering to diverse requirements including 24KV, 30KV, 33KV, 35KV, 36KV, and customized specifications as per customer demands. 2. Voltage Level: Available in a spectrum of voltage levels such as 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, and 22KV. 3. Type of Voltage Regulation: Choose between Off-circuit or On-load voltage regulation to suit your application's needs.
4. Tapping Range: Offers flexibility with a tapping range of ±5%, 2 increments of ±2.5%, and 4 increments of ±2.5% to fine-tune voltage adjustments.
5. Frequency: Designed to operate seamlessly at both 50Hz and 60Hz, accommodating various regional power standards.
6. Phases: Available in both three-phase and single-phase configurations to meet different operational requirements.
7. Connection Symbol: Designed with the flexibility of Dyn11, Yyn0, or customized connections as per specific requests.
8. Short-circuit Impedance: Built with standard impedance to ensure optimal performance and safety.
9. Altitude & Temperature: Suitable for altitudes not exceeding 1000m, and ambient temperatures not surpassing 40°C. If these conditions are not met, we will adjust parameters to align with industry standards.
We ensure that our transformers are adaptable to standard requirements, modulating parameters as necessary.
Power Capacity: With a range from 25 to 2500KVA, this transformer is engineered to handle a wide array of power demands.
Voltage Level: The transformer supports an extensive range of voltage options including 10KV, 11KV, 13.8KV, 15KV, 17.5KV, 20KV, 22KV, 30KV, 33KV, 35KV, and 36KV.
Voltage Level:
Type of Voltage Regulation: Opt for either Off-circuit or On-load regulation to best fit your system's specification.
Tapping Range: Offers adjustable voltage tuning with ±5%, 2 increments of ±2.5%, and 4 increments of ±2.5%.
Frequency: Compatible with both 50Hz and 60Hz frequencies, ensuring versatility across global power grids.
Phases: Engineered for flexibility with both three-phase and single-phase options.
Connection Symbol: Configurations include standard Dyn11 and Yyn0, with further customization available upon request.
Short-circuit Impedance: Ensures robust performance with standard impedance specifications.
Altitude & Temperature: Optimized for up to 1000m altitude and temperatures up to 40°C, with parameter adjustments available for other conditions.
If environmental conditions exceed standard specifications, we modulate product parameters to ensure compliance with industry norms.
The fully sealed oil immersed power transformer from Chaotai Power excels in delivering low loss, low noise, and high efficiency, culminating in superior energy savings and pollution reduction.
Distinct from typical oil immersed transformers, this cutting-edge model discards the oil conservator, adopting a design where oil volume changes are managed by the flexible corrugated tank. This air-isolated system effectively slows down oil and insulation degradation, thereby enhancing reliability and negating the need for routine maintenance during normal operations.
