The CEEG 220kV oil-filled power transformer is an indispensable asset for urban power grids, power stations, and large industrial and mining enterprises. This state-of-the-art transformer excels with a suite of remarkable attributes: high overload capacity, zero partial discharge, minimal noise, and robust short circuit resistance-all contributing to unparalleled stability in power supply systems. Through meticulous design, we've achieved a 20% reduction in no-load loss, a 5% decrease in load loss, and a 3-5 dB noise reduction compared to national standards. Available models include S11, S18, S20, SS20, SSZ20, SSZ22, OSSZ20, among others.
Our three-phase, three-winding 180,000kVA/220kV liquid-filled transformers are tailored for a variety of power station applications. Key features include:
1. No Partial Discharge : With an actual measured partial discharge of less than 50pC, our transformers outperform the industry standard, ensuring quieter and more reliable operation.
2. High Efficiency and Low Loss : Our innovative core and coil design, alongside advanced leakage magnetic flux control technology, significantly reduces both additional and stray losses.
3. Low Noise : With noise levels measured below 60dB, our transformers are quieter than national standards, ideal for noise-sensitive environments.
4. Intelligent Design : Fully compliant with the operational demands of modern intelligent substations, offering seamless integration and top performance.
5. Maintenance-Free Design : Featuring advanced air self-cooling systems, fiberglass dry-type bushings, and metal corrugated internal oil-type conservators, our transformers are designed for zero routine on-site maintenance, perfect for unattended substations.
6. Compact Structure Design : By employing the advanced 220kV end inlet method, we've achieved a highly compact structure that facilitates easier transportation and on-site installation.
7. Strong Short Circuit Resistance : We adhere to rigorous foreign short-circuit mechanical force verification procedures, ensuring that every assembly stage meets stringent design requirements for exceptional durability.
8. Over 40-Year Design Life : Utilizing a unique high-temperature-resistant hybrid insulation system based on temperature field simulation analysis, our transformers are built to have all components share the same extended design life.
9. Passes All Routine and Type Tests at Once : Achieving advanced domestic performance levels, our transformers pass all routine and type tests on the first attempt, guaranteeing reliability and efficiency.
