110 kV / 220 kV Oil-Immersed Transformer Cooling Solution
PC2800(2200)-33(3)/520 Gooseneck Panel Radiator
The PC2800(2200)-33(3)/520 gooseneck panel radiator from TengQi Technology (TQT) is designed for cooling applications in large-capacity 110 kV and 220 kV oil-immersed power transformers. It combines 2800 mm long panels and 2200 mm short panels to provide natural-cooling heat dissipation area while reserving installation space for bushings, piping and other external accessories.
This product is a heat-dissipation component within a transformer cooling system, not a standalone cooling system. Structural compatibility and cooling performance must be confirmed according to the specific transformer design and operating conditions.
Key Features
- Product Type: Gooseneck detachable panel radiator
- Compatible Equipment: 110 kV and 220 kV oil-immersed power transformers
- Panel Configuration: 2800 mm long panels / 2200 mm short panels
- Natural-Cooling Heat Dissipation Area: 51.68 m²
- Connection Type: Detachable flanged connection
Designed for Large Power Transformer Layout and Maintenance
Radiator layout for large oil-immersed transformers must meet thermal performance requirements while coordinating with bushings, oil piping, valve assemblies and peripheral accessories. With its long-and-short panel arrangement, detachable connections and outdoor protection configuration, the PC2800(2200)-33(3)/520 addresses practical requirements for space coordination and maintenance of large main power transformers.
Long-and-Short Panel Configuration
The differentiated panel arrangement helps coordinate heat-dissipation area with the positioning of external accessories, reducing structural interference in compact installations. This model provides a natural-cooling heat dissipation area of 51.68 m²; however, this figure alone cannot determine cooling capacity or temperature-rise performance.
Detachable Flanged Connection
The detachable design supports separate radiator transport, on-site installation and subsequent maintenance, facilitating lifting and service planning for large equipment. Interface, sealing and installation requirements shall be subject to project drawings and technical agreements.
Outdoor Corrosion Protection
The product features an all-welded panel assembly and a protective coating suitable for C3 corrosivity category environments. For coastal, high-salinity or other higher-corrosivity environments, the coating system must be confirmed separately.
Applications and Selection Considerations
This model can be used for large-capacity oil-immersed transformers in regional hub substations, renewable energy step-up substations, industrial captive power plants and heavy industrial or mining projects. Suitability for other specialized oil-immersed transformers requires further assessment of thermal requirements, interface conditions and installation structure.
Transformer losses, target temperature rise, oil circuit design, installation clearances and ambient temperature should all be verified during product selection. TengQi Technology can support product selection, structural coordination, manufacturing and quality verification based on project requirements. Final configuration and application scope shall be subject to the technical documents confirmed by both parties.
Regional Hub Substations
Suitable for large-capacity oil-immersed transformer projects where the space around the main transformer must coordinate the layout of bushings, oil piping and radiators.
Renewable Energy Step-Up Substations
Applicable to cooling systems for step-up transformers at renewable energy sites, subject to verification of ambient temperature, windblown sand, humidity and corrosion-protection requirements.
Industrial Captive Power Plants
Designed for transformer applications in captive power stations for large industrial and mining enterprises, balancing radiator layout, equipment maintainability and outdoor installation conditions.
Specialized Industrial Transformers
For industrial transformers such as rectifier and traction transformers, application may be evaluated after thermal performance and interface compatibility have been confirmed for the relevant voltage class and cooling requirements.
