CEEG 110/138kV oil-immersed transformers, also called liquid filled transformers, utilize a hybrid insulation structure, with DuPont Nomex insulation material (Class C heat resistance) used in the hot spot areas of the transformer. They use high-quality mineral oil or natural ester fluids. All indicators strictly comply with IEC standards, providing high overload capacity, safety, and reliability throughout their entire service life.
Operate continuously at 100% load at an ambient temperature of 40℃
Thermostability
Long-term operation at 220℃, short-term operation at 350℃.
No leakage promise
All sealing components made from acrylic in one-piece molding without joints
Design Life
＞ 30 years (seals have the same lifespan as transformer)
Attractive appearance
Same paint finish as household appliances and will not fade
Application Scenarios
Grid Expansion: Ideal for urban substations requiring low noise and high safety margins.
Heavy Industry: Perfect for mining, steel, and petrochemical sectors requiring an industrial transformer capable of withstanding harsh environments and variable loads.
Retrofit Projects: The high thermal density allows for capacity increases within existing substation footprints.
Core Technology
High-Temperature Resistant Hybrid Insulation System
Temperature field analysis software is used to determine the temperature distribution of the coil hotspots, allowing for the rational selection of insulation materials with different temperature resistance levels, ensuring that all components of the transformer's overall insulation system have the same lifespan.
7-Level Temperature Control Technology
We employ a "seven-level temperature control technology" for the temperature design of the entire transformer, including:
Insulation temperature control
liquid flow circuit temperature control
Overload temperature control
Core temperature control
Sealing temperature control
Component temperature control
Short-circuit temperature control
This method involves dividing the temperature distribution into five levels, starting from the hottest point near the windings and extending gradually to the cooler outer regions, also considering short-circuit and overload conditions, thus creating seven thermal states for temperature control design.
International Compliance and Performance Standards
Global Standard Compliance: All units strictly comply with IEC 60076 standards, ensuring seamless integration into European, Asian, and South American grids.
Efficiency Mandates: We address international requirements for reduced carbon footprints by adhering to IEC 60076-20 for energy efficiency, offering low no-load and load losses that rival or exceed Tier 2 efficiency recommendations.
Grid Resilience: Designed to meet high short-circuit withstand capabilities required by modern transmission system operators (TSOs), ensuring stability even during grid faults.
Grid Sustainability: Support biodegradable synthetic or natural ester fluids. This option eliminates fire risks (high fire point) and meets strict environmental protection regulations in water-protection areas or urban zones.
