The CEEG 220kV oil-filled power transformer stands as a pillar in urban power grids, power stations, and large industrial and mining enterprises. Revered for its high overload capacity, zero partial discharge, low noise, and robust short circuit resistance, it significantly boosts the stability of power supply systems. Our specialized design achieves remarkable reductions in losses and noise: 20% less no-load loss, 5% less load loss, and 3-5 dB lower noise levels compared to national standards. Available models include S11, S18, S20, SS20, SSZ20, SSZ22, OSSZ20, and others.
Our three-phase, three-winding 180,000kVA/220kV liquid-filled transformers are engineered for optimal performance across various power stations, featuring a suite of advanced attributes:
1. No Partial Discharge : The actual measured partial discharge is less than 50pC, significantly below the background noise level.
2. High Efficiency and Low Loss : Through innovative core and coil designs combined with advanced leakage magnetic flux control technology, we effectively minimize additional and stray losses.
3. Low Noise : The measured noise level is below 60dB, notably exceeding national standard requirements.
4. Intelligent Design : Specifically designed to meet the operational demands of modern intelligent substations.
5. Maintenance-Free Design : Our comprehensive design, featuring air self-cooling methods, fiberglass dry-type bushings, and metal corrugated internal oil-type conservators, eliminates the need for routine on-site maintenance, perfect for unattended substations.
6. Compact Structure Design : Utilizing cutting-edge 220kV end inlet method, the overall structure is compact, simplifying transportation and on-site installation.
7. Strong Short Circuit Resistance : Applying international standards for short-circuit mechanical force verification, we ensure every assembly stage meets stringent design requirements.
8. Over 40-Year Design Life : Our unique high-temperature-resistant hybrid insulation system, based on meticulous temperature field simulation analysis, guarantees all components share the same extended design life as the transformer itself.
9. Passes All Routine and Type Tests at Once : The transformer's comprehensive performance meets and surpasses advanced domestic standards.
