Product Description

Unveil the powerhouse that is the CEEG 220kV oil-immersed power transformer, a stalwart in urban power grids, power stations, and robust industrial and mining sectors. It stands out with its high overload capacity, zero partial discharge, ultra-low noise, and formidable short-circuit resilience, thus bolstering power supply system stability. With our innovative design, we have skillfully trimmed no-load loss by a remarkable 20%, load loss by an impressive 5%, and reduced noise levels by a noticeable 3-5 dB below national benchmarks.Available models span S11, S18, S20, SS20, SSZ20, SSZ22, OSSZ20, and more, catering to diverse power needs.

Explore our three-phase, three-winding 180,000kVA/220kV liquid-filled transformers, crafted for an array of power stations, featuring:

 

1. No Partial Discharge: Verified partial discharge measures less than 50pC, outperforming ambient noise levels.

 

2. High Efficiency and Low Loss: Pioneering core and coil design, coupled with advanced leakage magnetic flux control, significantly curtails additional and stray losses.

 

3. Low Noise: Measured noise levels fall below 60dB, substantially exceeding national standards.

 

4. Intelligent Design: Tailor-made to meet intelligent substation operational demands.

 

5. Maintenance-Free Design: Ingenious design integrates air self-cooling, fiberglass dry-type bushings, and metal corrugated internal oil conservators, eliminating routine on-site maintenance, perfect for unattended substations.

 

6. Compact Structure Design: Embracing the cutting-edge 220kV end inlet approach, it achieves a compact structure, easing transportation and on-site installation.

 

7. Strong Short Circuit Resistance: Employing global short-circuit mechanical force verification, all assembly stages adhere strictly to design specs.

 

8. Over 40-Year Design Life: Innovative high-temp-resistant hybrid insulation, backed by temperature field simulation analysis, ensures every component matches the transformer's extensive lifespan.

 

9. Passes All Routine and Type Tests at Once: The transformer's holistic performance reaches superior domestic standards.
