Product Description

The CEEG 220kV Oil-Filled Power Transformer is an exceptional choice for urban power grids, power stations, and large industrial and mining enterprises. It offers unparalleled advantages, including high overload capacity, zero partial discharge, low noise, and robust short circuit resistance. These features significantly enhance the stability of power supply systems. With a specialized design, we have achieved a 20% reduction in no-load loss, a 5% reduction in load loss, and a 3-5 dB decrease in noise levels compared to national standards. Available models include S11, S18, S20, SS20, SSZ20, SSZ22, OSSZ20, and more.

We offer three-phase, three-winding 180,000kVA/220kV liquid-filled transformers tailored for various power stations, boasting the following outstanding features:

1. No Partial Discharge : The actual measured partial discharge is impressively less than 50pC, even lower than the background noise.

2. High Efficiency and Low Loss : Featuring an innovative core and coil design combined with leakage magnetic flux control technology, this transformer effectively minimizes additional and stray losses.

3. Low Noise : The actual measured noise level is remarkably below 60dB, far surpassing national standard noise levels.

4. Intelligent Design : Engineered to meet the stringent operational requirements of intelligent substations.

5. Maintenance-Free Design : Incorporating air self-cooling methods, fiberglass dry-type bushings, and metal corrugated internal oil-type conservators, this transformer is maintenance-free, ideal for unattended substations.

6. Compact Structure Design : Utilizing the advanced 220kV end inlet method, this transformer boasts a compact overall structure, simplifying transportation and on-site installation.

7. Strong Short Circuit Resistance : Employs international short-circuit mechanical force verification methods, ensuring all assembly stages comply with design requirements.

8. Over 40-Year Design Life : Thanks to a unique high-temperature-resistant hybrid insulation system based on temperature field simulation analysis, every component of the transformer shares the same long-lasting design life.

9. Passes All Routine and Type Tests at Once : Demonstrating overall performance that reaches advanced domestic levels, this transformer excels in routine and type tests.

DuPont Nomex--World-Recognized High-Quality Electrical Insulating Materials
220kv Oil-Immersed Transformer with 31500-420000kVA Capacity and Multiple Secondary Voltages
Chemical Stability: Featuring excellent chemical stability due to the absence of weak C-H bonds.

Heat Resistance: Capable of stable operation at 220
ºC for extended periods and can endure short-term operation at 350
ºC. At 250
ºC, they do not melt, flow, or support combustion. Even at 750
ºC, no toxic or corrosive gases are emitted.

Safety and Environmental Protection: These materials are safe for humans and animals, producing low smoke and no harmful gases when burned.
