Product Details
PC1900(1600)-19(4)/480 Gooseneck Detachable Panel Radiator
The PC1900(1600)-19(4)/480 is a gooseneck panel radiator for oil-immersed transformers. With a staggered combination of 1900 mm long panels and 1600 mm short panels, it creates clearance space and adopts a flange-detachable connection, providing cooling support, installation clearance, and on-site maintenance access for transformer layouts with concentrated bushings, valves, and other accessories.
TengQi Technology (TQT) provides this radiator model to transformer manufacturers, EPC contractors, and power project customers. It is suitable for project-based matching of 10kV, 35kV, and medium-small capacity 110kV oil-immersed transformers. Actual suitability must be confirmed based on thermal requirements, interface configuration, installation space, and environmental conditions.
Radiator installation and maintenance needs in accessory-dense areas
Cooling components of oil-immersed transformers must not only provide the required heat dissipation area but also coordinate with bushings, valves, oil circuits, and the external equipment layout. When accessories occupy considerable space and conventional equal-length radiators cannot be directly arranged, the radiator's structural form, connection method, and maintenance accessibility become key verification points in design and project matching.
Accessory avoidance challenges
High- and low-voltage bushings, valves, or other accessories may restrict straight-line radiator placement, requiring long-and-short panel combinations to reserve the necessary space.
Restricted on-site maintenance
Outdoor stations or compact equipment areas require consideration of both installation and maintenance operations; detachable connections facilitate removal and replacement according to project specifications.
Environmental protection requirements
High temperature, strong UV radiation, dust, high humidity, or coastal salt-mist environments impose specific requirements on radiator surface coating and project anti-corrosion measures.
Connecting clearance avoidance, cooling support, and maintenance operations through gooseneck layout
The structural design of this model centers on radiator arrangement in restricted installation spaces. The purpose of each design element is not to replace the overall thermal design of the transformer, but to provide a verifiable cooling component basis for the transformer's overall layout, oil circuit configuration, and project installation conditions.
Staggered long-and-short panel combination
The 1900 mm long panels combined with 1600 mm short panels form a gooseneck profile, creating clearance zones at accessory-dense locations so the radiator layout can coordinate with bushings, valves, and other external components.
Flange-detachable connection
The radiator connects to the transformer via flanges, accommodating on-site installation, maintenance, or component replacement. Specific flange configuration, removal procedures, and operational requirements should be confirmed according to equipment interfaces and project installation specifications.
Continuous welding and integrated structure
The integrated continuous welding design reduces sealing weak points and addresses structural stability under outdoor transport, installation, and operating conditions. Welding quality and sealing performance are subject to the agreed manufacturing and inspection procedures.
C5 anti-corrosion coating for surface protection in complex outdoor environments
The product uses RAL 7032 coating with a designed total film thickness of 200 μm, meeting the project-required C5 anti-corrosion direction. This configuration can serve as a technical communication basis for radiator surface protection in high-temperature, high-solar-radiation, dusty, coastal salt-mist, and high-humidity environments. The specific coating system, salt-spray resistance requirements, and anti-corrosion grade acceptance methods are subject to the order technical documents.
A project-type cooling component integrated into overall transformer design
This gooseneck transformer radiator can be used for urban distribution stations, industrial and mining enterprise distribution transformers and rectifier transformers, renewable energy box-type substations and step-up transformers, as well as other oil-immersed transformer projects with restricted layout requirements. Its application must be verified together with transformer heat load, oil circuit design, flange interfaces, and installation orientation.
Transformer manufacturing support
During the transformer overall layout design stage, determine the radiator's structural configuration and installation feasibility based on accessory positions, cooling requirements, and interface conditions.
EPC and power project procurement
Conduct technical confirmation regarding project environment, anti-corrosion requirements, on-site space, and delivery documentation requirements, aligning cooling components with project equipment configuration.
Maintenance and replacement planning
The flange-detachable structure provides a structural basis for equipment inspection, radiator removal, or replacement work; specific implementation should follow on-site safety regulations and equipment technical requirements.
Suitable for projects requiring balanced clearance, cooling area, and anti-corrosion requirements
The PC1900(1600)-19(4)/480 is suitable for customers that need gooseneck transformer radiators for spatial coordination and wish to use detachable panel radiators to support on-site maintenance. The 22.44 m² figure is the self-cooling area of this model and does not equate to the final cooling effect of a specific transformer under all operating conditions.
Recommended information to verify before project confirmation
- Transformer capacity, losses, heat load, and required heat dissipation;
- Overall layout drawing, radiator installation orientation, and accessory positions;
- Oil circuit design, flange interface dimensions, and connection requirements;
- Ambient temperature, salt mist or dust conditions, and anti-corrosion standards;
- Applicable project standards, inspection documents, and packaging/delivery requirements.
Providing a clear structural option for oil-immersed transformer cooling support in restricted spaces
Through its long-and-short panel gooseneck layout, flange-detachable connection, continuous welded structure, and C5 anti-corrosion direction, the PC1900(1600)-19(4)/480 provides a panel radiator configuration for oil-immersed transformer projects that can be used for technical confirmation. Leveraging its transformer cooling product R&D, intelligent manufacturing, and project collaboration capabilities, TengQi Technology supports customers in translating cooling component requirements into drawings, manufacturing, and delivery; specific product suitability and service scope are subject to project technical documents.
